To specify how to treat discontinuities when offsetting surfaces, select one of the following options from the Offset toolbar:
- Always create an offset surface
preserves any discontinuities in surfaces during surface offset creation:
- Split surface at discontinuities
splits the surface at discontinuities during offset creation. The offset surface will be a solid, even if you started with a surface.The edges at the discontinuities are extended until they intersect:
A solid is created from the set of offset surfaces:
A discontinuity in a surface normal is defined by the Angular tolerance value in the Surface Discontinuity Tolerance section on the Units and Tolerance page of the Options dialog.
Note: Primitive surfaces are automatically converted into power surfaces.
If a curve or composite curve is dependent on a surface, its offset will lie on the surface.
To specify how to treat discontinuities when offsetting other objects, select one of the following options from the Offset toolbar:
- Retain discontinuities
preserves any discontinuities in the objects that are offset: - Round discontinuities
rounds any discontinuities when the objects are offset:
