Constraints

A constraint is a geometric or dimension relation between two elements.

A constraint is defined by:

	a type: for example, a distance constraint
	a mode: measured or constraining mode
	a configuration

A constraint applies to up to three elements. In Interactive Drafting workbench, constraints are created either through the dimension command, the constraints creation command or via SmartPick. Note that when you use SmartPick, you detect geometric constraints dynamically. But SmartPick can simply be used to automatically detect constraints without necessarily creating them.

If you want constraints to be created, before inserting constraints make sure the constraint creation option command is active in the Tools toolbar.

	Before you begin You should be familiar with important concepts.
	Create geometric constraints Set a relationship that forces a limitation between one or more geometrical elements.
	Create constraints between 2D and generated elements Create associative constraints between 2D elements and generated elements (Generative Drafting workbench).
