To Move Geometry Using Constraints
1. Select geometry to move.
2. Click Flexible Modeling > Move > Move using Constraints. The Move tab opens. The Automatic constraint is selected by default.
3. Select references for fixed geometry and moving geometry.
4. Use the dragger to place the geometry in the approximate position. Drag a handle to translate geometry, drag an arc to rotate geometry.
5. Type an offset value for the constraint.
6. Click to change the direction of the offset.
7. To move the selected rounds and chamfers that attach the moved geometry to the model, click the References tab and check the Transform selected attachment rounds/chamfers check box. If you do not check this check box, the selected attaching rounds and chamfers are removed and optionally recreated.
8. To set additional attachment and propagation options, right-click and use the shortcut menu or use the Attachment and Options tabs.
 
* When the Attach moved geometry check box is not selected, the resulting geometry is a quilt. The appearance of the original solid surfaces is propagated to both sides of the resulting quilt.
9. To maintain tangency between the moved geometry and neighboring geometry:
a. Click .
 
* If the flex_tan_propagation_default configuration option is set to on, tangency is automatically propagated.
b. If needed, set conditions for neighboring geometric entities using the Conditions tab, the Add condition option, or the shortcut menu.
10. To create a copy-move feature, click .
11. Click or middle-click to accept the feature.
