■ On the Place Constraint dialog box, select Pick Part First. Click the
component you want to constrain. Clear the check box to restore the
ability to select all components.
Selectable geometry is limited to features on the selected component.
■ Point the cursor to the required geometry. Right-click, and then choose
Select Other.
Click the arrows in the Select Other box to cycle through the underlying
face, curve, and point selections.
Click the green center button to accept the highlighted selection.
If you find it difficult to select faces, edges, or points, you can adjust the Locate
Tolerance option to change selection priority. Click Tools ➤ Application
Options ➤ General tab.
Workflow overview: Edit constraints
1 In the browser, right-click a constraint you previously placed.
The Edit Constraint dialog box is displayed.
2 On the Edit Constraint dialog box, specify a new constraint type (Mate,
Angle, Tangent or Insert).
3 Enter a distance to offset constrained components from one another.
If you apply an angular constraint, enter the angle between the two sets
of geometry. You can enter positive or negative values. The default value
is zero.
If Show Preview is selected in the Constraint dialog box, the position of
the components is adjusted to match the offset or angle value.
4 Apply the constraint through the Constraint dialog box or the context
menu.
The dialog box remains open, and you can apply as many assembly
constraints as required.
The following figures show before and after examples of applied assembly
constraints.
Mate Constraint
The mate constraint makes a set of geometry on one component coincident
with geometry on another component.
