Setting model units #472

Open GVladislavG opened 5 months ago

GVladislavG commented 5 months ago

Hello, XBim team!

How can I set model units? It's millimeters by default. How to set meters for example?

Thanks!

Assuming you mean the Project units? Have you seen how it's implemented here?:

If you want Meters rather than Millimeters, you presumably just want to remove the IfcSIPrefix.MILLI prefix during project setup.

Thanks! I set meters as units for Project. But now there is problem with showing model in viewers. I scaled all coordinates to meters while creating IFC-file. Test.zip

You will need to be much more specific about the issues. In general, these would be data related issues, not Toolkit or IFC issues.
