I have a 3d Sketch controlling a frame generator assembly. I needed to change a 2D sketch that was controlling the 3d sketch via "Include geometry"
However, When I changed the 2D sketch the entire 3D sketch turned pink and the sketch said there were errors in the constraints. Problem is I cannot find where the problem is...
I have narrowed it down to the lines circled in the screenshot (because when I delete them the problem goes away). But I have a lot depending on the frame members designated by those lines - So I dont want to delete them. I think the problem is in the reference at the point where the lines meet - but when I try to delete that reference it throws an error.
Any suggestions? Screenshot and .ipt are attached.
