Constraints solver accuracuy

[dnicolodi]

I am using cadquery to model a geometry that contains components that are separated by fairly small angles (of the order of on degree) but have large aspect ration (of order of a hundred) such that even minute misalignment results in non negligible errors in the positions of some vertexes. I observe the position of some vertexes to be computed inaccurately by the constraints solver. Indeed, increasing the verbosity of the solver, I see that the solver ends with EXIT: Solved To Acceptable Level. while it usually ends with EXIT: Optimal Solution Found.

Is there a way to improve the accuracy of the solver?

To begin with, you could try to adjust those options:

cadquery/cadquery/occ_impl/solver.py

Line 704 in fe53ca0

opti.solver(

It would be interesting to have a MRE

Thanks for your reply. It turns out that the issue was caused by a wrong constraint I was imposing. I didn't include a MRE because I was not able to reproduce the issue in a simple case. Trying to simplify my model while still exhibiting the issue I found the impossible constraint.
