Measuring units Karamba to IFC

Hi,

I have a question about Karamba. I want to use Karamba and make IFC files from it after the structure is done, but i know Karamba measures in meters while a program like Tekla measures in millimetres. Does this goes well with the IFC files or can i just make the structure in GH with sliders and use milimetres?

EDIT: Since i changed it to "meters", so the integers are only ranged from 0 to 10 most of the time, the model works faster and its compatible with karamba. I just need to know if it also works to make an IFC since IFC files have mm as the standard.
