To Offset Geometry
1. Select the geometry to offset and click Flexible Modeling > Offset. The Offset Geometry tab opens.
2. Drag the handle to set the offset dimension, or double-click the dimension, type a new number, and press ENTER.
3. To offset the selected rounds and chamfers that attach the offset 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.
4. To set additional attachment and propagation options, right-click and use the shortcut menu or use the Attachment and Options tabs.
 
* When the Attach offset 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.
5. To maintain tangency between the offset 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.
6. Click or middle-click to accept the feature.
