Offset feature from curved surface

Question asked by Christopher Thompson on Jan 30, 2008
Latest reply on Jan 30, 2008 by Kevin Quigley
I have curved face on a solid part which I would like to offset ~ .040 inches (w/draft) to create a pocket normal to the original surface as a cut. What is the SW equivalent feature to the Pro-E Offset Feature referenced below?

My best guess in SolidWorks is to use a split line (projection from plane) onto a curved surface, then use a thicken cut (surface). Is this the best option, or is a better option available in SolidWorks?

About the Offset Feature (Pro/Engineer)

You can use the Offset tool to create a new feature by offsetting either a surface or a curve with a constant or variable distance. You can then use offset surfaces to build up geometry or to create patterned geometry, or you can use offset curves to build up a set of curves that you can then use to build a surface. Various options are available from within the Offset tool, such as adding drafts to offset surfaces and offsetting curves within a surface.

You can create the following types of Offset features using the Offset tool:

Standard - Offsets a single quilt, surface, or solid face.

Expand - Creates a continuous volume between the selected faces of a closed quilt or solid sketch or, when using the Sketched region option, of an open quilt or solid surface.

With Draft - Offsets the region of the quilt or surface that is included inside a sketch, and drafts the side surfaces. You can also create straight or tangent side surface profiles with this option.

Replace - Replaces a solid face with a quilt or datum plane.
Curve - Offsets a curve or the one-sided edge of a surface in a specified direction.

Tip:

You can also open the Expand dashboard by selecting multiple surfaces and clicking Edit > 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 slide-up panel and use the Sketch dialog box. After defining an internal sketch, click EDIT (With Draft) to open the Sketch dialog box so you can edit the internal sketch. You can also use 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 slide-up panel and use the Surface Sets dialog box.
