Hello, Dima is right, Pro/E is not backwards compatible. You cannot open native Pro/E WF 3.0 Models in WF 2.0. That being said, you can save the WF 3.0 as a nuetral file and then open it in WF 2.0. You would perform a Save A Copy and choose the type as Neutral, IGES or STEP. Give that a try. The models will not be fully featured...but it will get the data in WF 2.0. Thanks, Mark
