Driving Contraint Error

Technical Inventor
1

I am trying to drive a mate constraint but after driving it an error pops up. It says:

“Cannot solve at (or near) this point. Check drive parameters and adaptivity settings.”

Can anyone help me get rid of this or tell me what the problem is?

Thank you for any help

More info is really needed. Also, a picture is worth a thousand words, so that would help too. And by a picture, i mean one where we can clearly see the area where you’re tying to constrain.

The front of the circle is mated to the back of that triangle-like shape. When I try to drive the constraint i get the error.

The most likely thing that will happen is the part could:

  1. Be over constrained (two constraints for the same thing)
  2. It is causing other constraints to fail such as a pivot point wont move or a part is constrained not to slide when it should.
  3. The two arts being constrained do quite match up right and are causing an alignment problem (.00000000000…000000000000001 in cad is too much off)

I would have to look at the file and see for myself what it is. But thanks for the picture it really helped.

I’ve been working to help trevor solve that problem. The parts can slide freely if dragged with the mouse, and if you manually set an offset at 1 inch increments it works without any errors. BUT , as soon as he tries to drive the constraint it moves about 1-2 inchs, stops, and then pops up the erros that he posted above.

He’s been working on this for 2 days and we’re starting to run out of excuses as to why it won’t work.
