About Projecting 3D Canonical Silhouette Edges

Keep in mind the following when using the Project 3D Canonical Silhouette Edges .

• You can re-limit the created silhouette edge using the geometry.
• The canonical silhouette command generates one or two marks (edges) if one mark is made of more that one curves. If those curves do not have the same geometrical support, the resulting canonical silhouette edges will not be associative (as for Projection/Intersection commands).
• Canonical silhouette edges are associative except in the case of a multiple distinct marks.
• A mark composed of several associated elements is managed as a single curve (you can constrain it).
• If you apply the Parents/Children...command to a sketch containing a 3D canonical silhouette, the Parents command shows the last solid feature that modified the canonical silhouette. To see an example of this, see Parents/Children section of the About Projecting 3D Elements onto the Sketch Plane topic.
