Using Assembly Constraints

This section describes the notions and operating modes you will need to set and use constraints in your assembly structure.

Constraints allow you to position mechanical components correctly in relation to the other components of the assembly. You just need to specify the type of constraints you wish to set up between two components, and the system will place the components exactly the way you want.

You can also use constraints to indicate the mechanical relationships between components. In this case, constraints are included in the specifications of your assembly.

	About Assembly Constraints
	Create a Coincidence Constraint: Click this icon, select the faces to be constrained and enter the properties of the constraint in the dialog box.
	Create a Contact Constraint: Click this icon and select the faces to be constrained.
	Create an Offset Constraint: Click this icon, select the faces to be constrained and enter the properties of the constraint in the dialog box.
	Create an Angle Constraint: Click this icon, select the faces to be constrained and enter the properties of the constraint in the dialog box.
	Fix a Component: Click this icon and select component to be fixed.
	Fix Components Together: Click this icon, select the components to be fixed and enter a name for this group in the dialog box.
	Quick Constraint: Check the list of constraint creation, click the icon and select the elements to be constrained.
	Change Constraint: Select the constraint to be changed, click this icon and select the new type of constraint in the dialog box.
	Deactivate or Activate Constraints: Select the constraint to be (de)activated and use the Deactivate or Activate contextual command.
	Select the Constraints of Given Components: Select the components, right-click and select xxx object -> Component Constraints contextual command.
	Editing Constraints: you can cut and paste , copy and paste and even delete constraints.
	Update an Assembly: constraints displayed in black indicate they need an update. Just click this icon.
	Update One Constraint Only: Right-click the constraint to be updated and select the `Update` contextual command.
	Modify the Properties of a Constraint: Double-click the constraint and enter new properties in the dialog box.
	Use a Part Design Pattern: Select the pattern, select the component to be repeated, click this icon and enter the specifications in the dialog box.
	Set a Constraint Creation Mode: Click any of these three constraint creation mode icons
