We are currently in the investigation stage of aquiring a CAD management program that will be utilized across international offices. PDML looks like the front runner at this time. I have been listiing to this Forumfor sometime now and would greatly appreciate your comments on PDML. What is PTC not telling? What are the right question we should be asking? If you had to go through this process again, would you still choose PDML or some other? What are the real problems associatedwith "Family Tables" and "Master Modeling Techniques".Some companies forbid the use of these techniques, WHY?
