There is a importer IFC2SKP

they were working on an exporter at one time... it never was released as far as I can tell.

I've tried the IFC2SKP importer some time ago. Works pretty well!
At work we are getting more and more IFC files, especially models of steel structures made in in Revit.

An exporter won't be as simple as an importer I guess. Somehow you need to add "building properties" to the "empty" SketchUp geometry.

That's exactly what I want to do, not try to re-build revit/archicad in sketchup, but create simple building elements that can be translated/labeled to meaningful objects, which could be re-used(via IFC) in CAD systems.

• faces can be given thickness and labeled "wall", "floor" or "roof"
• edges can be used as paths for profiles(like my current plugin) and labeled "wall", "floor" or "beam"
  I don't think there's much difference between a wall and a floor, so it could suffice to label these kinds of objects for conversion to IFC.

A tricky part is relations between objects. I think this can be done partly by keeping the base geometry as handlers. If a bounding edge of a floor plane is the same edge as the wall profile, then this edge's position/length can be the relation between floor(room/space) and wall.

Version 0.13.4:
It's now running on Mac (menu layout needs some more work).
Fix for SU8.
Partial fix for SU7: Auto-updating of modified objects does not work on SU7 because the "EntitiesObserver.onElementModified" method was added in SU8.

Version 0.13.2:
Improved monitoring of objects, feels much more solid!
Improved switching models without re-starting SketchUp
Improved undo
Fixed "reversed"-corners in flipped faces

Version 0.13.1:
Fixed switching between models without restarting SketchUp
bim-tools-0.13.1.rbz

Version 0.13.0:
Support for imperial units!
Thanks to the re-built menu (based on SKUI) it's finally possible to work in inches.
I removed the built-in IFC exporter for now and added some classifications for working with the official SU PRO IFC exporter.
I made some rather big changes under the hood, so if you encounter any problems, please let me know!

Version 0.12.4:
BIM-Tools working on SketchUp 2015!
Sorry for the absence, I'm up and running again
Next in line "imperial units"

bim-tools-0.12.4.zip

The goal of this project is to create a building modeller plugin for SketchUp with a real sketchup-like workflow(not a revit clone) that can interact with all kinds of other BIM tools through the IFC file format(I hope to re-enable this soon!).

I feel the best way to stay in the sketchup-workflow is to just use sketchup-faces for defining as many building parts as possible. Most building parts like walls and floors can be perfectly represented by a face with thickness!

That’s just what we will do:
Draw a basic building design like you normally would using the normal sketchup tools.

Select it’s faces and convert them to walls and floors with thickness(and meaning!) Using the shown "create"-button in the toolbar.

Change thickness and other properties using the dialog. Open dialog with "window"-button.

Use the "toggle"-button to switch back to the original faces.
Modify them if you like by moving/stretching, you will see the building parts move along!

Create windows by cutting holes in the faces.
Or place self-cutting components! http://support.google.com/sketchup/bin/answer.py?hl=en%26amp;answer=114533

Press the "toggle"-button again to see the the openings.

Add some section lines to better see the results!

Have fun!

Old versions:
Version 0.12.2:
Added a button to switch between manual and automatic mode.
When on manual mode all observers are disabled, this is faster when you are not editing BIM-Tools elements and should make sure that the plugin can never interfere with other active plugins.
bim-tools-0.12.2.zip

Version 0.12.0:

• The plugin is stable!

• Improved IFC export(Walls/floor-slabs/roof-slabs, still needs work)
  bim-tools-0.12.0.zip
  Version 0.11.0:

• Re-implemented basic IFC export(IfcPlate elements only)
  bim-tools-0.11.0.zip
  Check out the screenshots of some weird shape I exported to IFC.
  The IFC file needs a lot more "input"(building data) to be really useful(and proper connections between elements), but the basic exporter is working again!
  Version 0.10.6:

• added option to change wall length and height

• Fixed bug in "remove BIM properties tool"
  bim-tools-0.10.6.zip
  Version 0.10.5:

• Re-implemented "original" walls-from-edges tool

Version 0.10.4:

• Added button for removing BIM properties from source-faces
• Faces on the connection between elements are placed on a separate layer to improve sections

Version 0.10.3:

• Re-implemented self-cutting components!
