We’ve introduced an Off-Axis Mirror object in nonsequential mode. It has some advantages for users:
- The object has a coordinate system that is at the center of the off-axis part. (See sketch below.)
- This makes tolerancing and moving the part easier, because there’s no need to define motions with respect to the parent vertex.
- It also means that the edges of the part’s substrate are perpendicular to the surface slope at the vertex. This is more realistic for parts that are polished directly onto a blank (versus small parts that can be cut out of a parent part).
- It is simpler to define the off-axis apertures. The part supports native elliptical and rectangular apertures (including circular and square).
- The object simplifies the nonsequential editor, since a Boolean is not required to define the aperture.
