I'm having trouble piercing a sketch with my part. I'm able to pierce a circle prior to performing an extruded cut to the walls, however once the extruded cut is performed, I receive the error 'No intersection found for pierce point'. I'm assuming this is due to the cut breaking the circle? I've attached the drawing file. Any help is greatly appreciated!
The software won't let you establish a Pierce relation between the point and the edge you have highlighted because that edge doesn't intersect the sketch plane. You can use the shorter section of the radius instead (see below) and it will work fine. By the way, you had a sketch point coincident with the corner of the rectangle. I deleted it. The endpoint of any line works just fine for relations.
