Description

The Sketcher Offset tool creates equidistant edges around selected edges.

Equidistant edges around a closed (O) and an open (U) construction polyline

Usage

See also: Drawing aids.

Dim-OVP = Dimensional On-View-Parameters.

1. Select one or more lines, circles and/or circular arcs.
2. There are several ways to invoke the tool:
   • Press the Offset geometry button.
   • Select the Sketcher → Sketcher tools → Offset geometry option from the menu.
   • Right-click in the 3D view and select the Offset geometry option from the context menu.
   • Use the keyboard shortcut: Z then T.
3. The cursor changes to a cross with the tool icon.
4. The Offset parameters section is added at the top of the Sketcher Dialog.
5. Optionally press the U key or check the Delete original geometries checkbox to only keep the new outline.
6. Optionally press the J key or check the Add offset constraint checkbox to add a dimensional constraint between the offset outline and the original geometry.
7. Optionally press the M key or select from the dropdown list in the parameters section to change the tool mode:
   • Arc
   • Intersection
8. Pick a point to define the offset distance. Or with Dim-OVP: enter this distance.
9. The geometry is created and if Add offset constraint has been selected a dimensional constraint is added.

Limitations

This tool has certain limitations, mainly due to OCC issues:

• The following types of geometry are currently unsupported: ellipses, B-splines, hyperbolas and parabolas.
• Offsetting a single line can yield unexpected results.
• Open profiles are offset on both sides, creating a closed contour.
• External geometry can't be offset directly.
