Tutorial 7: Assembly

1. Introduction

In order to model a machine or mechanism in Pro/E, first the components of the machine need to be created as

individual parts using the part modeling techniques introduced in the preceding tutorials then these parts are

assembled together. Pro/E's assembly module allows parts to be grouped into assemblies or subassemblies to model

a complete machine or mechanism. In this tutorial, you will learn how to create assemblies, apply constraints

between parts, change view properties, create exploded views, and define cross-sections. These techniques will be

illustrated by assembling a slider-crank mechanism. The individual components of the mechanism are already available and thus we will immediately start creating the assembly.

2. Creating an Assembly

For this tutorial, you will need the components listed below. Make sure all files are stored in the same folder.

- Base.prt

- Bracket.prt

- Connecting_rod.prt

- Cover.prt

- Crank.prt

- Cylinder.prt

- Leg.prt

- Motor.prt

- Piston.prt

- Pin.prt

- M8_Bolt.prt

- M8_Nut.prt

- M8_washer.prt

- M8_BNW.asm

1. Start Pro/E Wildfire.

2. Choose [File] -> [Set Working Directory…], and select the folder containing the parts to be your working

directory.

Important note: It is recommended to save the assembly file in the same folder containing the parts used to

make the assembly. Also, after completing the assembly you should NOT rename or delete the part files or

move them to a different folder because they will be removed from the assembly and the assembly will fail to regenerate.

3. Select [File] -> [New].

180

4. Under the Type category in the New File pop-up window, change the type to Assembly .

5. Type the assembly name [Tutorial7] in the Text Box.

6. Since the parts are dimensioned in millimeters we will not use the default inches template, remove the

checkmark next to the option and click the [Ok] button. The New File Options pop-up

window will appear.

7. In the New File Options window scroll down in the list until you find the mmns_asm_design template and

choose it then click the [Ok] button.

Now you are looking at an empty assembly space since we did not insert any part yet. You should be able to

see the Assembly coordinate system and datum planes as seen in Figure 7.1. Now we will begin to add parts

to the assembly.

181

[Figure 7.1]

Adding the First Component

You can start the assembly by inserting any component you want, however, the assembly process will be easier if

you choose the first component wisely. It is better to choose a component that is in contact with several other

components to be the first component of the assembly. The best way to do that, imagine that you are going to

build the assembly in reality and choose a component to start with. For this reason we will choose the base to be our first component of the assembly.

1. Select the Add Component icon from the Toolbar at the right of the screen as indicated in Figure

7.1 (or choose [Insert] -> [Component] -> [Assemble…] from the Menu Bar).

2. When the Open pop-up window appears, click the [Preview] button at bottom-right of the

window such that you can look at the parts available in the folder.

3. Select the part named Base.prt, then click the [Open] button. This part will be the base on which the slider-

crank mechanism will be assembled. The Component Placement pop-up window will appear as shown in

Figure 7.2. This window will be used to select the necessary constrains in order to set the location of the

part.

182

4. Select [Coord Sys] from the drop-down menu under the Type category, as shown in Figure 7.2. Since this is the first component of the assembly we will use the coordinate system to set the location of this part.

[Figure 7.2]

Important note: The Placement Status is currently displaying No Constraints, as indicated in the figure,

because we did not set the constraints yet. When enough constraints are defined, the status message will

change to Fully Constrained. It is imperative that you see the Fully Constrained status message before you

close the Component Placement window for every component you add to the assembly.

5. To have a better view of the part, hide the datum planes and datum axis (since they are not needed at this

point) by clicking their on/off icons in the toolbar.

6. Select the part's coordinate system and then the assembly's coordinate system, as shown in Figure 7.3. This will align the part and fully constrain it. Note that the Placement Status has changed to Fully Constrained.

183

[Figure 7.3]

7. Select the [Ok] button from the Component Placement window to complete the placement and close the

window.

8. Hide the coordinate system (since we do not need it anymore) by clicking the on/off icon in the toolbar.

9. Select [File] -> [Save] from Menu Bar to save the assembly.

Adding the Cylinder-block

1. Select the Add Component icon, and select the part named Cylinder.prt, then click the [Open]

button.

2. Select [Mate] from the Type drop-down menu in the Component Placement window. 3. Select the top surface of the Base then select the bottom surface of the Cylinder, as shown in Figure 7.4.

184

[Figure 7.4]

Note that the Placement Status (in the Component Placement window) has changed to Partially Constrained

since the Mate constraint is not enough to fully fix the position of the component (the cylinder can still slide on

the surface of the base), therefore a second constraint is automatically added to the list. Additional constraints

will continue to be added until the placement status becomes Fully Constrained. If for any reason the new

constraint is not added automatically you can add it yourself by clicking the Specify a new constraint

icon. Also, if you want, you can remove an existing constraint by selecting it from the list and clicking the

icon.

4. From the Type drop-down menu, select the type of the second constraint to be [Align].

5. Show the datum planes by clicking the on/off icon in the toolbar.

6. Select the Cylinder's FRONT datum plane then select the Assembly's ASM_FRONT datum plane, as shown in

Figure 7.5.

[Figure 7.5]

185

Note that the Placement Status is still Partially Constrained and a third constraint is added to the list.

7. Hide the datum planes by clicking the on/off icon in the toolbar.

8. Set the type of the third constraint to be [Align]. 9. Select the back surfaces of the Cylinder and the Base as shown in Figure 7.6.

[Figure 7.6]

Note that the two surfaces will be aligned and the location of the part should be as shown in Figure 7.7. Also you should note that the Placement status has changed to Fully Constrained.

[Figure 7.7]

186

10. Now we will move the cylinder forward on the base by introducing an offset between the two aligned surfaces.

To do that, click on Coincident under the Offset category, then click on the arrow to open the drop-down

list and choose 0.0 from the list, as seen in Figure 7.8.

[Figure 7.8]

11. In the text box, instead of the 0.0, type -85 (minus eighty five) then hit Enter. Now the position of the

cylinder should be as shown in Figure 7.9.

12. Select the [Ok] button from the Component Placement window. 13. Select [File] -> [Save] from Menu Bar to save the assembly.

187

[Figure 7.9]

Important note: Every component that is added to the assembly will be shown in the Model Tree in the

same order it was added to the assembly. If you want to make a modification to any component in the

assembly (open, delete, edit, etc.), you can do so by selecting the component from the Model Tree, right-

clicking on it then choosing the option you want. For Instance if you want to modify the placement of the cylinder, you need to choose Edit Definition as shown in Figure 7.10.

188

[Figure 7.10]

Adding a Bracket

1. Select the Add Component icon, and select the part named Bracket.prt, then click the [Open]

button.

2. Select [Mate] from the Type drop-down menu in the Component Placement window. 3. Select the top surface of the Base then select the bottom surface of the Bracket, as shown in Figure 7.11.

189

[Figure 7.11]

4. Set the type of the second constraint to be [Align].

5. Show the datum axes by clicking the on/off icon in the toolbar.

6. Now we will select the axes of two holes on the base and bracket to align them (make the two axes collinear).

In order to minimize confusion and to make the selection easier, change the Filter type (at the Bottom-Right

of the Pro/E main window) from All to Axis.

7. Select the hole datum axis on the bracket labeled as A_4 then the hole datum axis on the base labeled as A_3 as shown in Figure 7.12.

190

[Figure 7.12]

The Placement Status will now be showing Fully Constrained but note that an assumption is

made where you have a tick mark next to Allow Assumptions, if you remove the tick mark the status will change to Partially Constrained.

8. We will add a third constraint in order to rotate the Bracket and place it in its correct position. To do so click

the Specify a new constraint icon in the Component Placement window.

9. Set the type of the third constraint to be [Align].

10. Select the hole datum axis on the base labeled as A_2 and the hole datum axis on the bracket labeled as A_5 as shown in Figure 7.13.

191

[Figure 7.13]

11. Select the [Ok] button from the Component Placement window. Now the location of the bracket should be as

seen in Figure 7.14.


[Figure 7.14]

Note: the number of constraints necessary to fully constrain a component depends on the type of constraints being used. It should be fully clear that any constraint you add can not contradict a previous constraint.

192

Adding the Crank

1. Select the Add Component icon, and select the part named Crank.prt, then click the [Open]

button.

2. Set the type of the first constraint to be [Insert]. 3. Select the surface of Crank shaft then select the surface of the hole in the Bracket, as shown in Figure 7.15.

[Figure 7.15]

Important note: The Insert constraint will not take the shaft and place it inside the hole. It will just align the

axes of the two circular surfaces similar to what will happen if you choose the Align constraint and select the

axes of the two circular surfaces. It should also be noted that the Insert constraint works only for circular surfaces.

4. Set the type of the second constraint to be [Mate].

5. Select the front surface of the Bracket then select the back surface of the Crank, as shown in Figure 7.16.

6. In the text field that appears in the Dashboard at the bottom of Pro/E main window (see Figure 7.16), type 1

then hit Enter to set the offset between the two mating surfaces to be 1 mm.

193

[Figure 7.16]

7. Though the Placement Status is now showing Fully Constrained, we will add an additional constraint in order

to rotate the Crank. To do so, click the Specify a new constraint icon in the Component Placement

window.

8. Set the type of the new constraint to be [Mate].

9. Select the top surface of the Base then select the side surface of the Crank, as shown in Figure 7.17.

10. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 60 then hit Enter to set the Angle offset between the two surfaces to be 60 degrees.

194

[Figure 7.17]

11. Select the [Ok] button from the Component Placement window. Now your assembly should look similar to

that shown Figure 7.18. 12. Select [File] -> [Save] from Menu Bar to save the assembly.

[Figure 7.18]

Adding the Connecting-rod

195

1. Select the Add Component icon, and select the part named Connecting_Rod.prt, then click the

[Open] button.

2. Select the type of the first constraint to be [Insert].

3. Select the surface of Crank pin then select the surface of the hole in the Connecting-rod, as shown in Figure 7.19.

[Figure 7.19]

4. Set the type of the second constraint to be [Mate].

5. Select the inner-front surface of the Crank then select the back surface of the Connecting-rod, as shown in

Figure 7.20.

6. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 1 then hit Enter to set the offset between the two mating surfaces to be 1 mm.

196

[Figure 7.20]

7. Now we will add an additional constraint to rotate the Connecting-rod, click the Add new constraint button

in the Component Placement window.

8. Set the type of the new constraint to be [Mate].

9. Select the lower surfaces of the Crank and the Connecting-rod, as shown in Figure 7.21.

10. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 101.63 then hit

Enter to set the angle offset. If the Connecting Rod is not oriented similar to what you see in Figure 7.22,

change the angle offset to 258.37 instead of 101.63 (which is the compliment of the angle i.e., 360 –

101.63).

Note that you have to set the angular offset to be exactly 101.63 degrees (or 258.37) and 60 degrees for the

Crank angle offset. These angles have been obtained from trigonometry based on the lengths of the Crank

and the Connecting-rod. If you do not set the angles to these exact values then you will have a problem later

on where you will not be able to fix the piston in its correct position.

197

[Figure 7.21]


that shown Figure 7.22.


[Figure 7.22]

198

Adding the Piston

1. Select the Add Component icon, and select the part named Piston.prt, then click the [Open]

button.

2. Select the type of the first constraint to be [Insert]. 3. Select the circular surfaces of the connecting-rod and the piston holes as shown in Figure 7.23.

[Figure 7.23]

4. Set the type of the second constraint to be [Insert]. 5. Select the circular surfaces of the piston and cylinder as shown in Figure 7.24.

199

[Figure 7.24]

Note: If the second constraint failed then the reason is that you did not use the correct angles for the crank and the connecting-rod.



[Figure 7.25]

200

Adding the Motor

1. Select the Add Component icon , and select the part named Motor.prt, then click the [Open]

button.

2. Set the type of the first constraint to be [Mate].

3. Select the back surface of the crank shaft and the inner surface of the motor as shown in Figure 7.26.

4. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 0 then hit Enter to make the two mating surfaces coincident.

[Figure 7.26]

5. Set the type of the second constraint to be [Insert].

6. Select the circular surface of the crank shaft and the circular surface of the motor as shown in Figure 7.27.

Note that all the circular surfaces of the motor are concentric; therefore you can select any of them for the insert constraint.

201

[Figure 7.27]




[Figure 7.28]

202

Adding the Cylinder-cover

1. Select the Add Component icon, and select the part named Cover.prt, then click the [Open]

button.

2. Set the type of the first constraint to be [Mate]. 3. Select the top surface of the base and the bottom surface of the cover as shown in Figure 7.29. 4. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 0 then hit Enter to

make the two mating surfaces coincident.

[Figure 7.29]

5. Set the type of the second constraint to be [Align]. 6. Select the side surfaces of the piston and the cover as shown in Figure 7.30.

[Figure 7.30]

203

7. Set the type of the third constraint to be [Align]. 8. Select the front surfaces of the piston and the cover as shown in Figure 7.31. 9. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 0 then hit Enter to

make the two surfaces coincident.

[Figure 7.31]




[Figure 7.32]

Adding the Piston-pin

204

Now we will add a new a pin in the joint between the piston and connecting-rod. However, the cover we just added is obstructing the view such that we can not see the joint; therefore we need to hide it.

1. Select the Cover from the Model Tree, right-click on it then choose the [Hide] option, as shown in Figure 7.33.

[Figure 7.33]

2. Since the cover has disappeared, we can add the pin now. Select the Add Component icon, and select

the part named Pin.prt, then click the [Open] button.

3. Set the type of the first constraint to be [Insert]. 4. Select the surfaces of the piston hole and the pin as shown in Figure 7.34.

205

[Figure 7.34]

5. Set the type of the second constraint to be [Align].

6. Select the flat surfaces of the pin and piston mount as shown in Figure 7.35. 7. In the text field that appears in the Dashboard at the bottom of Pro/E main window, type 1 then hit Enter.

206

[Figure 7.35]

8. Select the [Ok] button from the Component Placement window. Now your assembly should look similar to that shown Figure 7.36.

[Figure 7.36]

207

9. Since we are done with the pin now, we will unhide the cover. Select the Cover from the Model Tree, right-

click on it then choose the [Unhide] option


Adding another Bracket

Now we will add another bracket to support the other end of the crank where we will use the same Bracket again

but this time will be placed at a different location.

1. Select the Add Component icon, and select the part named Bracket.prt, then click the [Open]

button.

2. Set the type of the first constraint to be [Align] and select the side surfaces of the two brackets as shown in

Figure 7.37 and set the offset between the two aligned surfaces to be 0.

3. Set the type of the second constraint to be [Insert] and select the holes in the base and bracket as shown in

Figure 7.37.

[Figure 7.37]



208

[Figure 7.38]

Adding a Leg

1. Select the Add Component icon, and select the part named Leg.prt, then click the [Open]

button.

2. To position the leg inside the square opening on the bottom side of the base we will use the [Mate] constraint

three times as seen in Figure 7.39.

[Figure 7.39]

209



[Figure 7.40]

Adding the other Legs

Now we will add three more legs to the base, but instead of repeating the same procedure three more times we can do it faster using the Pattern tool.

1. Select the Leg you just added then select the Pattern icon from the side Toolbar. Alternatively

you can select the leg from the Model Tree, right-click on it then select [Pattern…].

2. From the Dashboard at the bottom of the Pro/E main window open the pattern type drop-list and change the

type to [Direction], as shown in Figure 7.41.

210

[Figure 7.41]

3. Select the long edge of the base, as shown in Figure 7.42, to define the first pattern direction.

4. Set the number of copies to 2 and the spacing increment to 520 mm as seen in Figure 7.42. If the pattern is

not going in the correct direction you can flip the direction using the Flip direction icon.

211

[Figure 7.42]

5. Click inside the direction 2 field (as indicated in Figure 7.42) to add a second direction for the pattern.

6. Select the short edge of the base, as shown in Figure 7.43, to define the second direction. 7. Set the number of copies to 2 and the spacing increment to 220 mm as seen in Figure 7.43.

212

[Figure 7.43]

8. Click the button in the Dashboard to complete the pattern. Now your assembly should look similar to that

shown Figure 7.44. 9. Select [File] -> [Save] from Menu Bar to save the assembly.

213

[Figure 7.44]

Adding Bolts

Now we will add the bolts used for mounting the cylinder and brackets to the base. However, instead of adding

the bolts, nuts and washers individually, the three pars have been assembled together as a single assembly. The

bolt-nut-washer assembly can be added together as a subassembly.

1. Select the Add Component icon, and select the assembly named M8_BNW.asm, then click the

[Open] button.

2. To position the bolt in the cylinder mounting hole we will use the flowing two constraints (as shown in Figure

7.45):

a. [Align] the axis of the bolt with the axis of the hole labeled as A_5.

b. [Mate] the lower surface of the bolt head with the surface of the cylinder mounting flange.

214

[Figure 7.45]

3. Select the [Ok] button from the Component Placement window. Now your assembly should look similar to that shown Figure 7.46.

[Figure 7.46]

4. Use a pattern to place bolts in the remaining three holes of the cylinder:

a. In the longitudinal direction 2 copies with 170 mm spacing.

b. In the transverse direction 2 copies with 100 mm spacing.

215

5. Select the Add Component icon, and select the assembly named M8_BNW.asm, and repeat the same

procedure described previously to place a bolt in one of the bracket holes.

6. Use a pattern to place bolts in the remaining three holes of the brackets:

a. In the longitudinal direction 2 copies with 60 mm spacing.

b. In the transverse direction 2 copies with 90 mm spacing.

7. Select [File] -> [Save] from Menu Bar to save the assembly. Your complete assembly should look similar to

that shown in Figure 7.47.

[Figure 7.47]

3. Modifying Appearances

216

In this section we will modify the appearance of the assembly by assigning different appearances to the different

parts. This is important for assemblies containing several parts where it makes it easier to distinguish the

different parts.

Assigning an appearance

1. Select [View] -> [Color and Appearance] from the Menu Bar. The Appearance Editor window will

open as seen in Figure 7.48.

217

[Figure 7.48]

The Appearance Editor window is divided into three sections (as indicated in the figure); appearance Selection, appearance Assignment, and appearance Properties modification.

218

In the Selection section, one can either choose one of the predefined appearances or define a new

appearance.

In the Assignment section, one can choose the entities (assembly, components, surfaces, etc.) to

which the selected appearance will be assigned.

In the Properties section, one can modify the properties of the selected appearance by adjusting its attributes (color, brightness, texture, reflectivity, transparency, etc.).

2. Click on the Add new appearance icon to define a new appearance.

3. Click on the Color adjustment icon to alter the color of the new appearance. The Color

Editor window will open as seen in Figure 7.49.

4. Click on the Color Wheel icon to open the color wheel.

[Figure 7.49]

5. Click inside the color wheel to select the color you want. Alternatively, you can adjust the color using

the R G B sliders.

6. Select the [Close] button to close the Color Editor window when you are satisfied with the new color.

7. To assign the appearance to selected components first click on the arrow next to Assembly

in the Assignment section to open the drop-down list and select

[Components] from the list.

219

8. With the left mouse button select the Base from the assembly, then while holding down the [Ctrl]

button on your keyboard select the four Legs.

9. Click the middle mouse button somewhere on the screen to complete the components’ selection

process.

10. Select the [Apply] button to assign the appearance to the selected components.

11. Select the [Close] button to close the Appearance Editor window. Now your assembly should look

similar to that shown in Figure 7.50.

[Figure 7.50]

Note: If the red highlight on the selected components did not disappear you can click on the Redraw icon

in the top Toolbar to remove the highlight.

Assigning another appearance

Now we will assign a different appearance to another component of the assembly. The new appearance will be

assigned to the cylinder Cover which is blocking the view of the piston; therefore this appearance will be made

transparent to make the piston visible. For each new appearance you want to assign you have to repeat the entire procedure all over again.

1. Select [View] -> [Color and Appearance] from the Menu Bar.

2. Click on the Add new appearance icon to define a new appearance.

220

3. Click on the Color adjustment icon to alter the color of the new appearance.

4. In the Color Editor window, click inside the color wheel to select the color you want.

5. Select the [Close] button to close the Color Editor window when you are satisfied with the new color.

6. To make the appearance transparent click on the [Advanced] tab under the Properties section in the

Appearance Editor window, then drag the Transparency slider towards the Clear option until you are

satisfied with the new appearance, as indicated in Figure 7.51.

221

[Figure 7.51]

7. Click on the arrow next to Assembly in the Assignment section to open the

drop-down list and select [Components] from the list.

8. Select the cylinder Cover from the assembly then click the middle mouse button somewhere on the

screen to complete the components’ selection process.

9. Select the [Apply] button to assign the appearance to the cylinder cover.

10. Select the [Close] button to close the Appearance Editor window. Now your assembly should look similar to that shown in Figure 7.52.

[Figure 7.52]

Assigning more appearances to other components

To assign different appearances to the remaining components of the assembly you have to repeat the same

process for each different appearance you want to assign. However you do not have to define a new appearance

each time where you can just choose from the predefined appearances and assign it to components. Figure 7.53 shows the assembly after assigning appearances to all components.

222

[Figure 7.53]

11. Select [File] -> [Save] from Menu Bar to save the assembly with the new appearance.

4. Exploded Views

In this section we will define an exploded view of the assembly such that each of the different parts constituting the assembly can be recognized easily.

1. Select [View] -> [View Manager] from the Menu Bar (or you can use the View Manager icon

in the top Toolbar). The View Manager window will open. 2. Select the Explode tab in the View Manager window, as seen in Figure 7.54.

223

[Figure 7.54]

As you see in the figure above a Default Explode is already defined, so we will see how it looks like before starting to define a new exploded view.

3. Right-click on the Default Explode and select [Explode] from the menu, as shown in the Figure

7.54. The default exploded view should look similar to that shown in Figure 7.55. However, this view is

not a very good exploded view where the components are positioned in somewhat arbitrary locations,

so we will define a new exploded view.

224

[Figure 7.55]

4. Before starting to define the new exploded view we need to return the assembly to its original

configuration by deactivating the default exploded view; so right-click on the Default Explode and

select [Unexplode].

5. Select the [New] button under the Explode tab, type [Explode1], and hit Enter.

6. Right-click on Explode1 (which you just created) and select [Redefine]. The Menu Manager will

appear.

7. Select [Position] from the Menu Manager. The Explode Position window will appear as seen in Figure 7.56.

225

[Figure 7.56]

8. Select [Plane Normal] from the Motion Reference drop-down list as indicated in the figure.

9. Select the upper surface of the base, as shown in Figure 7.57, such that the selected components will

be moved in a direction normal to this surface.

226

[Figure 7.57]

10. Click on any of the legs, you can now move the mouse up and down and you will see that the leg is

moving with the mouse in a direction normal to the reference surface you selected. Once you are

satisfied with the new position of the leg you just have to click once more to stop the motion of the leg.

11. Now repeat the same process by clicking on the other parts one at a time and moving them up or

down. By doing so you can move the different parts to convenient positions, maybe similar to what is shown in Figure 7.58.

227

[Figure 7.58]

12. To be able to move the parts in a different direction you just have to change the Motion Reference

surface by clicking on the arrow icon under the Motion Reference category, as indicated in Figure

7.59, and selecting a different surface to be the new motion reference, for instance you can choose the side surface of the base this time and stat selecting the parts and moving them normal to this surface.

228

[Figure 7.59]

13. Now repeat the same process several times by changing the motion reference surface and moving the

parts normal to that surface until you are satisfied with the positions of the different components in the

exploded view. 14. Select the [OK] button from the Explode Position window, and select [Done/Return] from the Menu

Manager. Figure 7.60 shows an example exploded view for our assembly.

229

[Figure 7.60]

15. To deactivate the exploded view and return the assembly to its original configuration, right-click on

Explode1 in the View Manager and select [Unexplode]. 16. Select the [Close] button to close the View Manager. 17. Select [File] -> [Save] from Menu Bar to save the new exploded view with the assembly.

5. Creating Cross-Sections

Cross-sections are commonly used in order to show the internal details of an assembly. In this section we will

define a simple "planer" cross-section for our assembly.

1. Select [View] -> [View Manager] from the Menu Bar (or you can use the View Manager icon

in the top Toolbar). The View Manager window will open.

2. Select the Xsec tab in the View Manager window.

230

3. Select the [New] button under the Xsec tab, then type [Xsection1], and hit Enter. The Menu
