Existing Tree Export

[Laura Stone]

I have exported existing trees to IFC with no problem in the past but having issues with a particular file.

If I try to export the trees I get an empty IFC file.  

If I copy and paste the trees into a new file they export with no issues but they are all at z=0

If I paste the site model into the new file the trees do nothing when I send them to surface.

Anyone have any ideas?

 

Thanks

Update on this, double checked the trees and they are displaying z=0 in the OIP but they are actually at the correct height in VW.

Then when exported to an IFC file they all drop to zero.

And another update, if I export the site model as well the trees export at the correct height.  But I don't want to include the site model in my IFC file.

And if I export only the trees and uncheck 'export site model' they export at the correct height, but only from the new file.
