I have a board style fixture with many custom shaped part cavities.  Now there is another version needed. After renaming and updating the drawing views to show the slightly different fixture, I noticed all my custom centers will not come in. I replaced the model  with a model that has the very same centers and center lines but they wont come in.  I'm ok with redoing all of the dims and annotations (though I shouldn't have to) but replacing 128 center lines is a bridge too far. should I just make a new drawing??
