Many have thought that history based constrained modeling was What’s called a “dumb geometry,” which is just the geometry withoutĪctually, dumb geometry is not geometry without design intent it Just want to start from scratch with an export and import.” (ExportingĪnd importing the model removes its feature history and turns it into There and chops and changes and has stuff copied in the wrong places,Īnd there’s not a logical system to it. “But you can have somebody that just gets in Structures their project in a good, thought-out, rigorous way, it’sįantastic,” Schwarz said. “If you work with somebody that's really good at parametrics and Is a quote from the referenced article above. So it was basically relegated to smallerĪssemblies or a family of parts where scaling was important. It was a bit convoluted and unless tightly controlled, could causeĬhaos in a large assembly. Sadly, this cool function took more maintenance than it was System and they called this functionality "Parametric Design".Ĭould program features that would relate to other features.Įxample: You have a control cable running down the keel of an aircraftĪnd it goes through a clearance hole. We found out that Pro/e was basically a programmable graphics design So what made Pro/e truly unique? It was created by If they would have developed CADKEY as their CAD solution.ĬADKEY or Catia? Boeing’s Billion-Dollar 3D CAD Mistake! I can tell you that Boeing would have been miles ahead I am sure it was this Pro/e envy that drove Boeing and Dassault toĬreate Catia 5. It wasįunny because this was years before Dassault released its Pro/e clone: Catia 5. That?" He said "We have to have history". The fellow asked "Is it history based?" CADKEY hadīoolean solids by that time and I asked "Why in the world would you want I remember trying to sell some more CADKEY It made "history based modeling" theīuzz word of the 1990's. To support the mainframe networked Catia 2 and 3 at the time. I was selling CADKEY to Boeing and all of their suppliers
Parametric 3d modeling definition Pc#
I was selling PC based 3D CADKEY at the time.
I have found many of theĬADDS 4 houses move instantly to Pro/e. But you could buy a single seat this offered incredibleįlexibility compare to the hugely expensive mainframe networked CADDS 4 and Catia. But it was not readilyĪvailable to most of the industry due to it being workstation based and Introduction of what was fondly called Pro/e. Both of these system were networked on mainframe Neither delivered a viable solution.ĬADDS 4 disappeared and Catia 4 moved to Boolean solids, the precursor At that time Computervision CADDS 4 and Dassault wereĭabbling in solid modeling. It was the first solid modeling system designedįrom the ground up. Groan about its complexity and limitations it was an incredible Pro/engineer was released in 1988 and as much as Shows there is a confusion with the term parametric design.
