Using Surface Faces for Edge Detection

When working with composite structures such as plane with holes in it or a partial sphere or cylindrical cutout filtering to the nominal feature doesn’t provide enough information to accurately detect the correct points. In these cases the CAD Faces can be save with the nominal feature to more precisely restrict the filter.

As an example consider a rounded corner on a CAD part. If you build the nominal cylinder from this face the filter process will include all the points within a proximity to that cylinder. The problem with this is that the CAD is only a partial cylinder and this will throw off the resulting fit as shown here in.

To properly filter to this face we have added the ability to record the faces used to build the geometry with the nominal cylinder selection. This can either be done through a right-click option added to the toolkit or directly through the relationship properties.

When a face is saved with the nominal geometry you will see it high- light with the geometry when it is highlighted as shown here in.

Using the CAD faces with the proximity filter allows you to ignore dat a beyond their extents an better isolate the data as shown here in.
