![]() The ability to define a master sketch, and base all necessary elements with a relationship on that sketch if particularly strong. In particular, it offers a full parametric tree, part-to-assembly logic, and any 3d object can be tagged as an IFC Element. Now, after understanding part-assembly logic, it immediately made sense! Clearly it doesn't have all the bells and whistles of Catia, but I have been testing it extensively over the past few months, and I believe that Freecad can offer a lot for AEC. However, it did get me thinking about manufacturing based workflow and I decided to try a software that I have opened many times before, but had no idea what to do in it - Freecad, an open-source sketch and constraints based 3d modeling program. That's ok, not every software out there needs to be open source. Having worked on a number of typical and complex projects, the value that I see in a Catia-based workflow is immense! Gehry and his partners saw this potential early on, and as the building industry becomes ever more complex, I am certain that there will be much more use of Catia in AEC. There are many more, advantages, but as a long-time Revit user (I've been using it since 2008), these three aspects completely break my rigid Revit boxed-in world. The third big advantage is that although there are tools for placing the correct IFC tags (like walls, facades, furniture, etc), any element could be tagged as anything. Another advantage is the part-to-assmebly logic, where almost any element could become a "part" and be used in another "assembly", whether a desk, window, floor, or building. One of the value added elements that Catia offers over Revit as a full parametric tree - everything can be related and the relationships are easy to understand in a tree format. Dassault likes to say that Catia can help you design a car from conception to production, and the factory for the cars as well. ![]() It started as an aeronautics and has expanded to manufacturing, automotive, industrial and product design industries (an many others). ![]() In case you are unfamiliar, Catia is a sketch-based parametric solid modeling program, capable of producing Class A surfaces. I attended a Catia for AEC event in London, organised by the excellent local Dassault reps from DTE and folks at Dassault Systemes Architecture, I have become convinced that a Catia-like workflow is the future of architectural design.
