IFC import geometry unwieldy

Does anyone know of a method to reduce the level of detail in the imported objects and profiles so that the intent (eg steel I beam) is maintained without the massive polygon count being generated?
Would also be useful to know of any methods for rationalising Morphs created from imported objects.

The Morph Tool has some commands for smoothing edges and faces but that may not give the result you are after. Other than that you can always select any unneeded edge and delete it (for example, if a planar surface is unnecessarily triangulated), but that may be drudgery if there are many such elements.
Please also note what I wrote in response to another IFC-related question, it may apply to your case as well:

We are already doing a version of that because of difficulty in getting the coordinate system coming out of the Revit IFCs.
Unfortunately the clean file that we are putting the Revit IFC into is barely navigable on its own and I'm too afraid to see what it does speed wise once I module it into our Teamwork project.
To give you an idea of the sizes we are talking about.
Teamwork file saved to a solo file as is = 140Mb
Solo file once all Sections, Elevations, Details and Layouts removed (ie model data only) = 5Mb
Clean ArchiCAD file with only the Revit IFC imported (no 2D data etc.) = 21Mb
If the structural model data alone is 4x the size of our architectural data we are going to have to start taking a lot of long coffee breaks while we wait for the sections to rebuild. (haven't had to do that since V11)

In discussions with our engineer we think it has something to do with the angle the end of the member is cut at.
- In ArchiCAD a beam end is always vertical (unless you start doing SOE to it)
- In Revit a beam end is always perpendicular to the beam's axis and needs to be modified to give a vertical end if that is what the design requires.
It seems too much of an imposition to ask the engineer to design the beam ends in the project just to suit the limitations of IFC.

No that's not a black material; that's the number of faces blurring to infinity. And at only half way through design development we already have over 1000 of these.

If the IFC already has a high polygon count than it has something to do with how it is exported from Revit.
If it has high polygon count only in ArchiCAD, then the ArchiCAD import of IFC is the culprit.
