To Mirror a Geometry
1. Perform one of the following actions depending on the mode:
In part mode, select one or more surfaces of a part geometry.
Hold down the CTRL key to select multiple surfaces of a geometry.
2. Click Home > Mirror. A Live Toolbar appears. Click to see the Floating Dashboard.
3. Select a mirroring plane.
4. To mirror curves or datums:
a. Click the Curves and datums collector in the Floating Dashboard. If Floating Dashboard is collapsed, click .
b. Select one or more curves from the Graphics Window.
c. Click the arrow below the Curves and datums area, to see References.
5. To reattach modified geometry to the same solid or quilt where it was originally attached, select the Attach geometry check box (selected by default). If Floating Dashboard is collapsed, click to attach geometry.
6. To store attachment properties:
a. Clear the Attach geometry check box.
b. Select Store attachment properties check box (selected by default).
7. To recreate round or chamfer geometry that connects the selected geometry to the rest of the model, after attaching the modified geometry, select the Recreate rounds and chamfers check box (hidden below Attach geometry check box). Available when Attach geometry check box is selected.
8. To select bounding edge references:
a. Select the Attach geometry check box.
b. Click the Bounding edges collector.
c. Select one or more edges from the Graphics Window.
9. To preview a geometric solution, click or one or more times. Or select from the adjacent list.
10. Select Maintain rounds and chamfers check box to keep round and chamfer attributes (radius and type) connecting the selected geometry to the rest of the model.
If Maintain rounds and chamfers check box is not selected, then round or chamfer is treated as a part of the selected geometry.
11. Middle-click to complete.
