      I've been using intersect_with to find the intersection of a cylinder (a group) and a prism (another group), where the prism is skewed relative to the prism. In some, but not all, instances the method drops an edge. Here's a pic:

      The intersection breaks when you try it manually as well -- easy to fix, but rather undermines the idea of a plug-in! I'm attaching an abbreviated model.

      Any ideas??

        I confirm the weirdness.
        At first I thought that perhaps the dims were too small - but they are not [~43mm] !
        Or the axes were messed up - they are not!
        That one face refuses to intersect 'with the model' unless you move it [slightly]...

        It's plain weird πŸ˜•

          Weird indeed but moving the prism up 1mm solves the problem.

          Nothing is worthless, it can always be used as a bad example.
