Sometimes I find the boolean subtract operation just doesn't do its job.

 

Today I had this semicircle that I wanted to cut off at 225 degrees and at every curve I make to subtract at this angle this happens:

When I change the angle somewhat it works like it should.

Perhaps I'm missing something here, but I think it's easier to use the Pie Tool to create the exact angles you want, and then convert to curves and delete the radii.

Hi tcarisland

I've just tried this myself and it appears to work as I would expect. Any chance you could attach the file from your first screenshot please?

Thanks for the file. I've reproduced the issue, it looks to be caused by the edges sharing the exact same space. If I drag the triangle out a little bit (to the right and down) then it will work as expected. I'll pass it on to development.
