To Create Offset Geometry
1. Select one or more surfaces and click
Home >
Offset.
A linear dragger appears on the selected surface. A Live Toolbar appears.
2. Click
to see the Floating Dashboard.
3. Pull the dragger to the required offset distance. Or, double — click the dimension value visible in the Graphical Window, type a new value and press ENTER. Alternatively, type a value in the Offset by value box and press ENTER. Or select a previously used value. Offset geometry is shown in preview in graphics window.
4. To flip the offset direction, click
.
5. Select the
Maintain tangency check box to keep existing tangency between modified and directly adjacent surfaces of the geometry. If Floating Dashboard is collapsed, click
.
|  Use default conditions check box is available if Maintain tangency check box is selected. It is used to set system defined conditions for the selected and surrounding geometry. |
6. Click the Condition collector (below Use default conditions check box) to activate it. Select one or more surfaces, edges or vertices from the graphics window. Select one of the following conditions:
◦ Fixed: Fix a surface, edge or vertex
◦ Fixed with tangency: Fix a surface while maintaining tangency to neighbouring dragged surfaces or surface regions
◦ Fixed axis: Fix an axis or a surface of revolution
◦ Fixed center: Fix the centre point of a sphere or a torus
◦ Fixed normal: Fix the normal direction of a planar surface
◦ Constant R1 : Keep the radius of revolution of a torus constant
◦ Constant R2: Keep the radius of the section of a torus constant
◦ Constant angle: Keep the cone angle constant
◦ Fixed pole: Fix the apex of a cone
◦ Propagate through: Allow changes to a round surface and the neighbouring tangent surface to keep tangency
◦ Fix underlying edge: Fix a point on the underlying edge which has been rounded or chamfered
◦ Constant R: Keep the radius of a cylinder or sphere constant
◦ Keep spherical: Prevent a sphere from becoming a torus
7. Click Add to create a condition between the selected geometries.
Click Remove to remove a selected condition from the list of conditions.
Click Remove All to remove all the conditions from the list of conditions.
8. To reattach modified geometry to the same solid or quilt where it was originally attached, select the
Attach geometry check box. If Floating Dashboard is collapsed, click
.
| When the Attach 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 store the attachment properties to use when you reattach the moved modified offset geometry to the model, select the Store attachment properties check box. Attachment properties specify how a selected modified geometry reconnects to the rest of the model. Available when Attach geometry check box is not selected.
10. To recreate round or chamfer geometry after the selected geometry is moved and attached, and to close the gaps created by the moving geometry, select the Recreate rounds and chamfers geometry check box. Available when Attach geometry check box is selected.
11. To select a bounding edge reference:
a. Select the Attach geometry check box.
b. Click the Bounding edges collector.
c. Select one or more edges from the Graphics Window.
12. To preview a solution click
or
one or more times. Or select from the adjacent list.
13. Click 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 part of the selected geometry.
14. Middle-click to complete.
