Applying Dimensional Constraints and Creating User Parameters

Dimensional constraints allow you to control object sizes with specific numerical values, and to set up dynamic dimensional relationships with mathematical equations and formulas. User constraints are not tied to specific geometry but hold values calculated from dimensional constraints. In the following steps, you will create dimensional and user constraints:

1. If the file is not already open from performing the previous step, go to the book's web page, browse to Chapter 12, get the file Ch12-B.dwg, and open it.
2. Select the ribbon's Home tab, open the Layer drop-down in the Layers panel, and select Layer 2 to make it the current layer.
3. Select the Parametric tab on the ribbon. Select ...
