ProDESKTOP - Modelling Building block This exercise will introduce you to the three main functions of ProDESKTOP. In the process you will create a simple building block for a child's construction kit. This will form the basis of a texture-mapped image and an orthographic engineering drawing.
• Run ProDESKTOP.
• If the Tip of the Day window appears, click on Cancel.
• Click on , start a New File.
• Maximise the design window.
The modelling window is showing a workplane with arrows at the origin (0,0).
Draw a rectangle
• Select , the Rectangle tool.
• Draw a rectangle on the workplane by clicking and dragging with the mouse.
Don't worry about the size of the rectangle for the moment.
ProDESKTOP is creating hidden constraints as you draw. The rectangle has perpendiculars in each corner and parallels on opposite sides.

You can make these visible.
• Click on , the Select Constraints tool.
The size of the rectangle doesn't matter because you will now add dimension constraints to control the length & width.
Add a constraint
• Select , the Add constraint tool.
• Click near the centre of the lower left line and drag away to position the length constraint.
Changing view.
The View pull-down menu contains a number of options.
Try some of these:
• Autoscale
• Half Scale
• Zoom in
• Manipulate.

Adding a constraint - method two
For the width constraint you will use an alternative method.
• Make sure , the Add constraint tool is still selected.
• If any of the lines in the rectangle are highlighted in red, click on a blank part of the design window to deselect them.
Hint: If you click on a blank area of the screen when nothing is selected the Add constraint tool will de-select.
• Click on the lower left-hand line. It will highlight in red.
• Click and drag from the upper right-hand line to drag a constraint.
Changing the value of a constraint.
• Click on , the Select Constraint tool
• Double click on the text of one of the constraints.
A Properties dialogue window will open.
• Alter the value of Length to 31 mm.
• Click on .

• Repeat this with the other dimension constraint.
Extrude
Now you are ready to use the Extrude feature to create a solid object.
• Click on , the Extrude tool.
The Extrude dialogue window will open.
You could type in an extrusion distance however, an alternative method is to drag the extrude 'handle' to define the extrusion distance dynamically.
• Click on the yellow extrude handle and drag upwards until the extrusion distance settles on 50 mm. You may need to pause as you drag to allow the computer to catch up. It is doing some heavy calculations!
Hint: If the dialogue window is hiding the yellow extrude handle move it by dragging the title bar.
• Release the mouse button.
• Click on .
You now have a cuboid.

Creating a new workplane and sketch In order to create a circular button on top you need to sketch a circle on the top face of the block. To do this you will create a new workplane and sketch.
Creating a new sketch and workplane.
• Click on , the Select Faces tool.
• Click just inside the top face of the block to highlight it. The surface will turn red when selected.
• Open the Workplanes pull-down menu.
• Click on New sketch.
The New Sketch dialogue window will open.
• Change the sketch name to Circular bump
• Change the Workplane name to Top of cuboid.
Hint: It is good practice to use appropriate names for workplanes, sketches and features to make subsequent editing easier.
• Click on .
A new active workplane is located on the tope face of the cuboid with the origin located centrally.

• Click , the Circle tool.
• Click and drag from the centre of the top face of the block to create a circle.
Constrain the size of the circle
• Click on , the Sketch dimension tool.
• Drag from the edge of the circle to create the constraint.
Tim Brotherhood ProDESKTOP page 10 of 27

• Click on , the Select Constraint tool.
• Double click on the diameter constraint.
• Alter the value to 24.
• Click on .
Extrude the button.
Whenever you click on the extrude button it will operate on the currently active sketch.
• Click on , the Extrude tool.
• Drag the extrude handle a distance of 4 mm.
• Click on .
Your model now looks like a building block.
Changing the viewpoint.
You have already experimented with some of the view tools.
• Use the manipulate tool (or keyboard arrow keys) to change the viewpoint to this looking underneath the block.

The model needs to be hollow to allow blocks to stack.
Hollowing the block
The tool used for this is called Shell. Before choosing the shell tool you must have a face selected.
• Click on , the Select Faces tool.
• Move the mouse just inside the bottom face of the block.
The perimeter of the base will pre-highlight in cyan.

• When the cyan outline is visible click.
The outline turns red to show it has been selected.
• Click on , the Shell tool.
• Change the offset value to 3 mm.
• Click on .
• Save your work.
Your building block is complete.
Before moving on to the next section experiment pressing the F9-F12 keys.

Now you are working in the drawing window, dimensions can be created and they can be made to conform to international standards. They will also print out.
Linear dimension
• Select , the Linear Dimension tool.
• Click one of the vertical edges of the block.
• Click and drag from the opposite parallel edge to position the dimension text.
Hint: Notice how the first line selected remains highlighted. This makes chain dimensioning much quicker.
• Create linear dimensions on other parts of the drawing.
Hint: unexpected results when creating dimensions are usually caused by a line being highlighted before you start the dimension. Click on a blank part of the screen if you need to de-select an object.
Diameter
Radius and diameter dimensions are even easier to create.
• Select , the Diametric Dimension tool
• Click and drag from the top of the circular button on the end elevation to position the diameter text.
