1 DRAFTING and DIMENSIONING 98

2 A properly dimensioned drawing of a part is very important to the manufacturing outcome. With CATIA, it can be a very simple process. This simple Guide Block will show basic dimensioning formats. 99

3 There are a few simple ways to go from Part Design to DRAFTING. If you double click the Part Design icon (top right hand corner) you will access a navigation window as shown. From here, you can pick DRAFTING. Part Design icon Choose DRAFTING 100

4 Another way to do it is to click the START drag-down menu and choose DRAFTING. Drafting 101

5 The NEW DRAWING CREATION dialog box will appear. The first thing to do is pick your automatic layout. Next, you can choose MODIFY and change ISO and ANSI standards, number of sheets and orientation, scale and others. Orange shows it has been chosen 102

6 Quickly the drawing is generated. All of the views we asked for in proper orientation to each other. This drawing is now ready for dimensions. Since the front view is highlighted, we can start there. 103

7 Click on DIMENSIONING from the toolbar… …And then choose a curved surface to dimension. Chosen surface DIMENSIONING 104

8 If default is DIAMETER, this is what you will see. If you wish to dimension a RADIUS, highlight the line and right click on it. 105

9 When DIMENSION TYPE appears, notice that it is default to Diameter. Highlight RADIUS Center and click on it. 106

10 Your dimension is now a Radius. Lengthen and shorten the dimension line by dragging it. Click and Drag 107

11 You can add notes before and after the dimension by clicking on the red triangles Red triangles 108

12 This text box will appear. Simply click in the empty field next to “Text After” and type the note. Click on OK when you’re done and your note will appear in the drafting. Type note here 109

13 In this example, “TYP” was typed to indicate the dimension is TYPICAL for these radii. After you have clicked in the box to enter your note as seen on the previous page, press the “Space Bar” once to leave a space between the dimension and your note as seen here 1 Space 110

14 All lines can be done in the same way. Simply pick them and click on Dimension. If you are working on a large drawing, this single line picking would be rather tedious. There is another way… 111

15 Click on GENERATING DIMENSIONS Step By Step. This will allow CATIA to do the dimensioning for you one at a time, every few seconds, whatever timeout you choose. Generating Dimensions icon Click here to start the dimensioning. 112

16 Once all of the automatic dimensioning is finished, you will get an ANALYSIS of what was done. 113

17 After the Auto Dimension, you may want to go back and make changes. This is as simple as highlighting the dimension and making the appropriate change. 114
