To Create Offset Surfaces by Expansion
Use the Expand option to create a continuous volume between the selected faces of a closed quilt or surface. You can also constrain the offset area of an open quilt or solid surface with a sketch.
1. Select a surface, and click Model > Offset. The Offset tab opens.
2. Select Expand as the type of offset.
3. Type the required offset value in the offset value box. An offset surface is created parallel to the reference surface.
4. Click the Options tab to specify the offset method:
Normal to Surface—(default) Offsets the surface normal to the original surface.
Translate—Translates the surface along the specified direction. Click the Direction reference collector and select a plane, a flat face, a linear curve or edge, an axis, or a coordinate system as the reference.
* Changing the offset type from Normal to Surface to Translate, and vice versa, causes all children of the offset feature to fail.
5. Click to finish the offset.
You can also open the Offset tab by selecting multiple surfaces and clicking Model > Offset. If you select solid surfaces and closed quilt surfaces, the default Expand area type is Whole Surface. If you select open quilt surfaces, the default Expand area type is Sketched Region.
If Sketched Region is selected, you can click Define on the Options tab and open Sketcher to define a sketch. If an internal sketch is already defined, you can click Edit to open the Sketcher so you can edit the internal sketch. You can also right-click and choose Define Internal Sketch and Edit Internal Sketch from the shortcut menu.
If you are using a surface set as a reference and you want to modify it, click Details on the References tab and use the Surface Sets dialog box.
