IFC and SEO

Anonymous — Tue, 02 Mar 2010 18:01:20 GMT

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.

It looks like the solid elements you are using to cut the openings are being exported. Try exporting visible layers only. You could also hide (or even delete) them in Revit.

Tried that already, no luck. Can't delete it, it doesnt appear to even create the cut out.

Why not just use doors instead of SEOs then?

Because it's an extruded slab, to create the wall panels. I can model it differently if needed. But do SEO's work at all when exporting as IFC? After a basic slab test I believe not unless I am missing a setting.

I've had no significant problems with SEOs and IFC.

In AC11 I had some elements appearing in Revit which represented some roof cuts using SEOs. They appeared as yellow wireframes and were easily deleted with no ill effects.

Perhaps if you set the SEO layer to wireframe.

If your SEO layer is set to wire frame try changing it to solid and then save out for IFC.

Please add your AC version and platform to your profile.
Which AC are you using?

Has SEO and IFC worked for you?

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.
