how to connect or refer a sketch to the geometry of another body

[giant1114]

I can see the "shapebinder" but I assume the vertex of the line I draw should snap to the shape binder but it doesn't. If that's not how it works how do I connect?

The most frequent error with ShapeBinders is, that their source is still visible and then you cannot select them. I recommend to make everything invisible except the ShapeBinder..

I also tried this but still no luck.

A vertex doesn't snap all by its own. You have to use the shapebinder together with Sketcher External.

Ok Thanks, that helped.
