Null Reference Exception

Hi everyone!

I get the following error when importing an IFC, but I have been using this file lately without problems. The previous IFCs that I had baked work properly. Any ideas? 

Thank you!

Hi,

Can you please share the ifc file (either post or email) and I'll take a look?

It can be that a data expiry issue can occur, and if you save the gh script, close and open (forcing a recalculation) then immediately bake, then there is no expired data and it should generate a valid file.

If it is data expiry, these can be pretty tricky to trace and detect, but if I can access the problematic ifc file it might help.

Cheers,

Jon
