Good morning, I tried and wanted, but I couldn't find a solution to this problem.
can be combined with the angle cut two different profiles like those in the photo?
Why is there so difficult to attach the model?
What you see in the hole is not already a shortening?
what result do you want to get (imaginena please)?
depends on how the model is made.
banally do one or two sketches and cut the superfluous
if the two bodies overlap you can do a single sketch representing the tilted line and then with greed you eliminate what you do not need
