Constraint Creation Mode

This task shows you how to set one of the three modes available to create constraints. These modes are:

	Default mode
	Chain mode
	Stack mode

Open the Constraint_Creation.CATProduct document.

Default mode

Click the Default mode

icon if not already activated.

This mode lets you create as many constraints as you wish by explicitly selecting two geometrical elements. In our example, you can set an offset constraint between the highlighted face and the face of another geometrical element. For the purposes of this scenario, double-click the offset constraint icon to make it permanently active.

The offset constraint icon still active, you can then set another offset constraint between two other faces.

2. For the purposes of our scenario, delete these constraints.

Chain mode

Click the


      Chain

icon.

This mode lets you create as many constraints as you wish by always reusing the last face you selected.

2. The offset constraint icon still active, you can then set another offset constraint between the second face you selected and any other face.

The offset constraint

icon still active, you can then set another offset constraint between the third face you selected and any other face.

And so on...

4. For the purposes of our scenario, delete these constraints.

Stack mode

Click the


      Stack

icon.

This mode lets you create as many constraints as you wish by reusing the very first face you selected to create the first constraint.

2. The offset constraint icon still active, you can then set another offset constraint between the first face you selected and any other face.

3. The offset constraint icon still active, you can then set another offset constraint between the first face you selected and any other face.

4. And so on...
