I have struggled with this for many hours trying to follow tutorials and I'm not getting anywhere. As you can see from the photo, I simply wish to modify this drawing by changing the curved strap to a rectangular one. When I rotate the object the lines will not rotate with it. When I zoom in to see if the lines have snapped to the corners, they are always a distance apart.
Please tell me how to do this (the controls), so the lines snap together and I can blend it to the original.
