When I get done with the model, numbering, etc... I make a single parts drawing, all my single parts show up on the drawing, and all the single part numbers/quantities are correct, but the drawing list makes no sense. It will be missing quantities that should be there, and/or make up quantities that should not be there...Ie., I have 2 p1000's but it says I have 3 p1000's etc...I can correct this by going back to the model to make preliminary part marks, or sometimes take out preliminary part marks, but it is a trial/error process.......Also, when trying to edit an already existing drawing, say I delete a part and make a new one. It makes nice clouds and revision marks, but the part I deleted more often than not stays on the sheet and the new part I made will not show up even after running any "force updates/revision updates etc...furthermore the parts lists are never correct after making said revisions. I've even tried deleting the lists off the page, and making a new one, doesn't do anything.Thanks for any help.
