[EnergyPlus_Support] Re: IFC>IDF problems

Thanks, Rob.
I figured out that my problem was I didn't create the "space" in 
ADT3.3. I put in six surfaces(1roof/1slab/4walls) only and think that 
ADT3.3 will know the volume enclosed by six surfaces is a space.
Now I created the space in ADT.
When I run IFCtoIDF with the IFC(2x) exported by GtsIfc2xUtility in 
ADT3.3, the error message is:
The instruction at "0x10003658" referenced memory at "0x00000004".
The memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program
the debuging window shows:
Unhandled exception in IFCtoIDF.exe(EPLUSBSCLIENT.DLL): 0xC000005: 
Access Violation
When I export the IFC(1.5) by the ADT3.3 and run IFCtoIDF,
it was successful, 1 zone and 4 exterior surfaces/walls showes up.
The problem "no space instances" is solved.
But there are still no roof and no floor in the IDF.
