I have just edited the existing plant symbols (as 2d symbol) from the library (as recommended in the training lit.) and when I import them into an existing drawing started in v12.5 (currently a 2008) they import fine and I can drop them in from the resource guide fine. But when I try and edit the generic symbol with the place plant tool, it crashes every time (12 times and counting) I have tried to edit the drawing and remove anything connected with the old plant list. I even copied and pasted the geometry into a new blank drawing, no luck. Help I don't want to have to redraw everything. I have tried editing the new symbols in blank drawings with the place plant tool and it works fine???? Any thoughts?
