I have the following problem: I've made an angled wall end tool (generic model family with a void sweep) with an angle parameter. When I place it at the end of a curved wall, and set an angle more than 70 (for example 75 degrees), I get the error message "Can't cut instance out of Wall". With angles 70 or less, or when the component is not at the end of the wall (or is actually even closer to the wall end), the void is cut just fine. A screen shot and the family file are attached...
