At the risk of going slightly off-topic here, I’d like to debate the applicability of MVDs. As @jwouellette states, tessellation of walls are not in scope for a DTV. However, in Blender, where BReps are the native format, tessellated walls are exactly what Blender wants to do a design transfer. In f…

Today we need to find which paradigms are the best and the majority use/implement? and nominate them. Which I think today (IFC4) IFC has had a lot of improvement in geometry/topology (LoD) What’s BIM? There’re a lot of definitions, but for me from the first day “BIM is virtual representation of rea…

@tauscher Thank you for your comments. Yes, it seems to be really difficult up to impossible to support full conservative geometry roundtrip. On the other hand, the current situation is incomprehensible: Why are there several different “best ways” to model an ordinary wall? Does this diversity …

It is a technical fact that it is not possible to convert from any geometry representation to another geometry representation without loss of data. The concept of “geometric roundtrip” refers to the ability to move between software that support exactly the same geometric representation. Even if one …

“Yes, it seems to be really difficult up to impossible to support full conservative geometry roundtrip.” This is exactly my point about the geometry dilemma. What’s information to one, is wortless for the next person. As i see it multiple shapes and appearances should be included in one model. Whic…

@Moult , I absolutely agree with the fact that different geometry representations are useful for different purposes and there is no superiority or inferiority per se. @Herb ,this is not a random choice of software developers or vendors, but driven by what that specific software is meant to do - author…
