Ceiling profiles?

[m.knutsson]

Hi,
When I export my ceiling 600x600 grid (starting with default arch template) I get no profiles in my exported IFC (Coordination view 2.0). How can I get them to show? Maybe my question is how to get them visible in my model as profiles (just rectangular ones)!?

Regards,
Mat

The grid of an ACT ceiling in Revit is just a pattern on the surface of the ceiling, it is not dividing the geometry of the ceiling into a grid. No my knowledge, there is not a way to use the Revit ceiling tool to give you a panelized ceiling. If you are willing to consider a workaround, I'm sure one could find something to make it work. To what other software are you exporting the model that you want to see the grid? How do you want to use the model in another software?

It's a BIM-thing an not software related. The BIM-coordinator (can be on whatever IFC-based soft) wants the profiles to check clashes with the MEP-models and also visually see the profiles. The quantity person and production people (also on any IFC-based soft) wants gross and net area (IFC Base Quantities for Ceiling). Pretty basic stuff. I'm testing Revit and ArchiCAD for the same reasons...that is how they deal with the basic IFC quantites. Both ArchiCAD and Revit can export their "own" psets and properties but a Ceiling has quantities defined through the IFC 2x3 schema as base quantities and it's those I'm after.

If you really want modeled ceiling tiles and track, make a mass the size and shape of your ceiling, and place a curtain system. Curtain panel is the Tile, mullions are the track, perimeter mullions are the perimeter supports.
Done.
I only suggest this to our interior group when they really want to get a good rendered look for Wood Slat Ceiling. Otherwise, I say use the pattern. But I'm more on the production side of things not the qty take off side of things.
Also that level of development is way beyond anything I would ever need to show.
