Summary 0003299: Sketcher should check redundant coincidences used with tangent constraints
Revision 2018-01-03 20:34 by Kunda1
Description There is a corresponding issue for the ValidateSketch tool: 0003298.

The tangent constraint is often used together with a coincidence constraint instead of applying it to the endpoints instead.
This often leads to problems in subsequent steps.

So maybe something could be done about that in the Sketcher, but I don't know what, and how complicated it would be.

    Make the solver detect these conflicts and warn the user about it?
    Make the solver detect these conflicts and transparently replace the dual constraint with the proper point-on-point tangent constraint?

NormandC
I would prefer the first solution, doing something automatic might prohibit the possibility to have the erroneous situation as an intermediate step.
