3-D CAD: Modeling with product variation as the design intent--Equations allow simple edits to make complex changes

摘要

Figure 1a is a screen shot of a 48-in. part with 47 holes equally spaced and centered along its length. In Figure 1b, the data in the Custom Properties form has been changed to specify a 6-in. part with two holes. Both figures use the same CAD model; no edits were made to sketches. Just type, click on Apply, and then click on Rebuild to change the model.
