How to delete all dangling constraints?

james_mcpherson11762

I'm trying to build some parts libraries from other cad formats. Since Onshape can't import .dxf's I'm importing the 3D models, creating a new sketch, then using the "Use/Project" feature to project the 2D curves onto the sketch. This works (although it is tedious, 2D import into a sketch should exist), however when I then suppress the no-longer needed 3D model, each and every line has a dangling constraint referencing the original 3D model. I end up with hundreds of dangling constraints that I'm currently deleting one at a time... this hurts.

Is there a better way?

@James_McPherson11762 I have put in an improvement to project with USE with an option to not add constraints.  A constraint manager would be another option and is also in the list for improvements.

I don't know of a way to delete all dangling sketch relations inside OS.

I do mess this dialog from SW and it's capabilities:

Has this been resolved in any meaningful manner? I'm sketching 'in context' and the use constraints, which I no longer need after the sketch has been created from another sketch are everywhere. The next sketch will be based upon this new sketch, or another context, but the use constraints will be in the way for the next step. Deleting them one by one is tedious to say the least.

Would like to 'use' a previous sketch without the 'use' constraints. Any way to do so?

Me too.

Is there a "Delete all constraints from selected entities"?

Nevermind, I found a way to remove all constraints from a sketch. You just select the lines / objects you care about, do ctrl + c to copy, then right click a plane and click "paste sketch" and it will be pasted without any of the constraints.

RyanAvery  nice one. Unfortunatly you have to constrain the pasted elements again.
