....I found a tut that said all you have to do is use the move tool on the midpoint of an arc and you can change the bulge. all my arcs are still intact but they are full of endpoints and not main mid point. any attempt to use the move tool moves the entire arc. any one know what's going on?
If your arc has an even number of segments, then, as Dave suggested, use the 'Move' tool (nothing selected previously though) to move that endpoint in the middle of the arc.
If your arc has an odd number of segments, than you should look for the midpoint right in the middle of the arc, to perform the 'Move' operation to change the bulge.
If your arc is grouped, then enter its editing context (double click on it) to be able to change the bulge.
