Using the silhouette edge of a parallel blend as a sketching reference

[Guest]

Someitmes you want to use the silhouette edge of a parallel blend for a sketching reference. However, when you try to select the edge as a sketching reference, it selects the surface of the blend, not the edge.

While in sketcher, click Sketch > References > Xsec Ref Ent and pick the surface that the silhouette edge belongs to as the 'reference surface' that intersects the sketching plane. Then you can sketch an entity that snaps to this reference entity.
