Jochem is on a distinguished road

I have runned the tutorial with the snappyHexMesh (motorBikeTutorial ) succesfully.

I want to use this tutorial to simulate airflow past buildings. To try if this work i first simulated a simple case using a square building and put this in the "wind tunnel". I've first drawn this building in Inventor and saved as .stl. When i've simulated this case i've notticed that openFoam automatically changed the dimensions from mm to m. So the "wind tunnel" was to small for the building. To solve this i've redrawn the building in inventor and drawn every dimension as if the dimensions where in m.

Now i am using a really complicated .stl file where it is not possible to change the dimensions in inventor. I guess the problem still occures because when i use the normal dimensions i get a really weird surface, with strange interruptions and not the shape that i've drawn.
And i have first runned a checkMesh and there where no illegal triangles.

When i adjust the dimensions with convert to meters (where i use 1000 in stead of 1), and i do blockMesh and snappyHexMesh, i can not see the .stl file in ParaView. Its just like the case hasn't found the .stl file and the wind tunnel is empty.

Can anyone help me with this problem?
