IFC to Rhino - Extract Geometric Representation for Volume Calculation

Hey @m-clare!

Thanks for bringing this up! I guess this is due some documentation or blog post to clarify a bit how our IFC import works, and what assumptions do we make.

When importing an IFC file, we try to keep the data structures as close to the original as possible, but there is one big difference in Speckle that I think is what’s causing you confusion:

For every item that has some geometric information, a mesh representation of that element will be attached to the displayValue property. This is the same behaviour that the Brep class, and all of the BIMand Structural elements work.

So basically, I think you’re looking for this :point_down:

Let me know if this is not exactly what you were looking for, we’d be happy to poke around at your use-case :slight_smile:

On a side note, the IFC import service still has quite some room for improvement, so we’d love to hear your thoughts on what works, what doesn’t and what you’d wish to see in it in the future!
