IFC and SEO

[Anonymous]

Does anyone know if there are limitations with SEO created in ArchiCAD and saving as IFC? See images below.

I have tried a few different IFC options.

Walls trimmed by the roof using SEO retain their trim, but not the SEO relationship.

Walls and slabs used to cut holes in roofs and floor slabs using 'subtract' do not retain either the holes or their SEO relationships.

Why did I think SEO would survive IFC?

The only trim action with SEO that even partially worked was the walls trimmed by roofs. The same elements trimmed with non-roofs , the evidence of trimming.

This is a BIG problem! GS needs to be sure that ALL modeling tools (including Complex Profiles, SEO, etc.) translate correctly via. IFC. If we can't get clean .IFC files out of ArchiCAD, we aren't any better than Revit users (without the large user-base).

Do you have the latest beta IFC addon for 12? There was one posted at the end of October. See if it helps.

Yes Michael.
Did you get different results when you tested this?

I haven't had a chance to test it yet, but that IFC addon fixed quite a few issues we were experiencing.

I agree with David.

But overall I am (and my client) was pleased with the translation. To the average Revit user I doubt they would even know it originated in ArchiCAD. Just as many AutoCAD users dont know dwgs orginated in ArchiCAD.

As a workaround you can save your SOE as an object, then save your model. This worked for me.
