When detailing a part, you have to select a corner to set you zero when using ordinate dimensions. Sometimes new detailers mix up the zeros when projecting them to views and have floating o-lines on the drawing. It would be nice if there was an option to auto assign the o-line origin to a part to reduce errors.
