In SW assembly, I use often the "Path mate" (Mate -> Advanced Mate) in order to constraint a part along one path. I never had a problem to do so in 2D and in 3D by using a 3D sketch.
Recently, I wanted to constraint a bead along a wire (see pictures below). The wire has been obtained with the function "sweep" using a project curve as a path.
In the assembly it seems impossible to use the project curve as a path for a "path mate":
Does someone has an idea why it doesnt work? Is it possible to realise this constraint with others mate conditions?
