IFC import => how to translate Revit Stories for ArchiCAD

Paul King — Tue, 27 Sep 2016 07:59:42 GMT

HI, I have an IFC file produced in Revit Structure that I need to import without the process also generating a lot of unwanted extra stories in ArchiCAD that are only useful in Revit.

How can I merge through the Revit geometry and layers, but have the geometry map to the closest ArchiCAD story? Or even all just to one story at a pinch?

This process is likely to be repeated a few times wit successive iterations of the structural model, so the translation from one story structure to the other needs to be simple and quick.

No prospect of getting the engineers to restructure their model to suit us - no budget available for them to do so. Ditto for us unfortunately.

There is one thing you may ask those Revit guys to try.
In Revit Stories are defined by Level objects. These Level objects are placed in Sections or Elevations and they can be set to define a Building Story.
Select a Level object in Revit and check its "Building Story" property. If it is checked, the Level defines a Building Story.
Maybe they should check whether this property is set correctly for all their Levels defined in the Revit file so it is checked only for those Levels that are actual Stories of the Building.
Also, I think they should check if all their objects are constrained to these Building Story Levels, an not to any other auxiliary Levels they might have defined in their file.
This may clean up thing a bit.

Thanks Laszlo - I will see if I can convince them to try!
