Currently there does not appear to be a tool to constrain a Line, Circle etc to a Face of a Solid.
It would be very useful to provide a tool to constrain the 2d Constraints solving plane associated with these elements to a user-selected Face.
At the moment, the Edges forming the face are recognised by some of the Constraints tool, but the inability to bind the Lines etc to the Face results in unusable results.
Use cases include defining openings and other features in Linear Solids (Walls, Beams), Solids (Slabs / Roofs), Extrusions (Columns) etc.
The tool should also extend to the new Associative Extractions.
