I'm looking for how to constrain a stroke (or other) of a sketch that has been created on a surface in relation to an edge of the piece.
When I project the geometry (or the edge of my part) I can constrain my sketch with it but the problem is that the projected geometry is part of the sketch and when I want to make an extrusion of my sketch, the projected lines make a mess...
If you know how to use the edges of the piece to constrain a sketch without having to project them, please help me.
it is possible to convert the entities and then you have to select them and on the left check "for construction" and these edges will no longer be a problem, otherwise it is possible to place dimensions between an edge of a 3D part and a sketch.
It is also possible to constrain the entities of the sketch without projecting the curves. However, to have access to the selection of entities located outside the sketch, you must activate the appropriate setting in the selection bar ("In the workpiece only" at least, instead of "In the active sketch only").
