About Constraints Creation in 2D Layout for 3D Design

You need to know a few background information about constraint creation in 2D Layout for 3D Design.

The following are discussed:

Before You Begin

If you want constraints to be created, make sure the Show Constraints icon , and optionally the Create Detected Constraints icon , are active in the Tools toolbar, before you start creating constraints. Refer to Using Layout Tools for more information on these options.

Maximum Number of Elements

A constraint applies to up to three elements.

Constraint Creation via Smartpick

Constraints are created either through the constraint commands or via SmartPick. When you use SmartPick, you detect geometrical constraints dynamically.

But SmartPick can simply be used to automatically detect constraints without necessarily creating them. For more information, refer to the Using SmartPick task in the Sketcher User's Guide.

Constraint Creation via Smartpick

In the 2D Layout for 3D Design workbench, dimensional constraints do not exist as such. It is by creating driving dimensions that you can drive constrained geometry.
