PROJECT EXERCISE P11B

This project exercise provides point-by-point instructions for creating one dynamic blockto represent several symbols for flanges with differing dimensions, as shown in thesingle-line depiction on the right of Figure P11B–1. In this exercise, you will apply the skillslearned regarding creating dynamic blocks, acquired in Chapter 11.

Figure P11B–2 shows the differing dimensions of raised-face weld-neck flanges intwo flange ratings (150 and 300 ) for two different pipe sizes (3 00 and 4 00). The fourblock references can be obtained from a single dynamic block that has been created withvarying dimensional parameters driven by a Lookup Table with the different pipe-size/flange-rating combinations.

In this project, you will learn to do the following:

• Start the Block Editor and draw the objects for making a dynamic block.

• Add parameter sets to the dynamic block.

• Add a Lookup Table for controlling the dimensions of the block referenceafter it is inserted.

Step 7: Invoke the RECTANGLE command from the Draw panel to draw the Flange(without the weld-neck hub), as shown in Figure P11B–5. AutoCAD prompts:

Specify the first corner point or 0,–3.75

Specify the other corner point or @. 9375,7.50

Step 8: Invoke the PLINE command from the Draw panel to draw the hub (the weld-neck), as shown in Figure P11B–5. AutoCAD prompts:

Specify the starting point: .9375,–2.125

Specify the next point or[Arc/Halfwidth/Length/Undo/Width]: @1.8125,2.125

Specify the next point or[Arc/Close/Halfwidth/Length/Undo/Width]:@–1.8125,–2.125

Specify the next point or[Arc/Close/Halfwidth/Length/Undo/Width]: (ENTER)

FIGURE P11B–4 Block Editor



NOTE The dimensions of the geometry are arbitrarily drawn to comply with those of the 3 00-150flange; flange O.D. ¼ 7.5 00, length ¼ 2.75 00, and thickness ¼ 0.9375 00. They could just as wellbe drawn to comply with the dimensions of one of the other three pipe-size/flange-ratingcombinations, or even rounded off to dimensions that aren’t on any of them. Once the ac-tion/parameters have been created and the block has been inserted, these action/para-meters can be used to change the values to comply with the proper dimensions. Also, forthis exercise, the thickness will be ignored (it is for appearances only and does not affectthe overall piping makeup dimensions) as will the dimension for the base of the hub whereit attaches to the flange.

Step 9: From the Parameter Sets tab of the Block Authoring Palettes window, invokethe LINEAR STRETCH parameter set. AutoCAD prompts:

Specify the starting point or (select Label from theshortcut menu)

Enter distance property label <Distance>: LENGTH(ENTER)

Specify the starting point or (select midpoint of theface of the flange, as shown in Figure P11B–6)

Specify the endpoint: (select the endpoint of theweld-neck)

Specify the label location: (specify the labellocation, as shown in Figure P11B–7)

Select the objects: (press (ENTER) to complete theselection)

FIGURE P11B–6 Selecting the points for Linear Stretch parameter set

FIGURE P11B–7 Placement of the label for the linear stretch



This completes the assigning of the stretch action.

Step 11: Similarly assign two additional Linear Stretch parameter/actions from themidpoint of the flange face of the flange to the upper and lower corners ofthe face (see Figure P11B–8). Name the Linear Stretch parameter set for thetop one as Half Flg Dia 1 and bottom one as Half Flg Dia 2. On each end, usethe crossing selection to select the rectangle representing the flange and thepolyline representing the weld-neck to be the geometry associated with theactions. Be sure to select only the appropriate end and not the whole rectan-gle representing the flange.

Step 12: Select Lookup Parameter from the Parameters tab. AutoCAD prompts:

Specify the parameter location or (choose a pointnear the geometry to place the lookup parameter)

Double-click the exclamation mark of the Lookup parameter. AutoCADinvokes the Lookup Action and prompts:

Specify the action location: (choose a point to placethe lookup action)

AutoCAD displays the Property Lookup Table (see Figure P11B–10).

Step 13: Choose Add Properties and AutoCAD displays the Add Parameter Propertiesdialog box. Select Linear in the Parameter Name listing as Add inputproperties type (see Figure P11B–11) and choose OK. AutoCAD returns youto the Property Lookup Table dialog box where you can enter the values forthe properties under the LENGTH column.

FIGURE P11B–10 Property Lookup Table

FIGURE P11B–11 Add Parameter Properties dialog box



Step 14: Under the LENGTH column, specify the values for the flange lengths for eachpipe-size/flange-rating combination. Under the Lookup column in theLookup Properties section, enter each pipe-size/flange-rating (see FigureP11B–12). Below the Lookup column, change the “read-only” selection to“Allow reverse lookup.” Choose Audit, and if there are no duplications orerrors, AutoCAD will display the “No errors found” alert. Choose OK toreturn to the Property Lookup Table dialog box.

Step 15: Repeat steps 13 and 14 for the Half Flg Dia 1 and Half Flg Dia 2 parameters,adding the values for the half diameters of the flanges (see Figure P11B–13).After adding all the values, choose OK to close the Property Lookup Table di-alog box.

NOTE Whenever you make additions to the data, the text box under Custom changes back to“read only.” So be sure to repeat the following part of step 14: ‘Below the Lookup column,change the “read-only” selection to “Allow reverse lookup.”’

Step 16: Close the Block Editor. AutoCAD displays an alert stating “Changes to para-meters may update existing block references in ways that are not always ob-vious. N block reference(s) exist(s) in the drawing. Save block definition andupdate block references?” Choose Yes to finally exit the Block Editor and re-turn to the drawing screen.

Step 17: Insert the newly created dynamic block and then select the lookup grip.AutoCAD displays the Lookup Table shortcut menu (see Figure P11B–14)from which you can choose the pipe-size/flange-rating combination. Thedimensions will automatically change to comply with the selection.

Step 18: Using the newly created dynamic block, create the Single-line drawing ofthe Piping Arrangement, as shown in Figure P11B–1. Save the drawing withthe name RFWN-FLG.
