Hello,
I would like to learn abot parametres to IFC “instructions” within IFC file. E.g. “IFCCARTESIANPOINT” - here it’s clear that the instruction takes one point of x, y and z coordinates. But what about “IFCGEOMETRICREPRESENTATIONSUBCONTEXT”? I’d like to understand meaning of each parameter, its kind (point, array, enum, string, …), its “optionality” and so on. Where should I find some study stuff? Or is there a something like “Guide to IFC File (Format) for Beginners”?
Best regards,
Lukas
Hi,
Have a look at
For the schema, see the attributes table at e.g:
^ that is the 4.3 version of the schema.
