Model Units change question

When I open the Revit model and Rhino.Inside and after some time will change Revit unit from m to mm I got this message. This all correct.

My question is do I need to go to rhino and change Units to Meters or I must save Revit in Meters and open again project in meter so Rhino will also be in the same units. Are both option safe?


Yes is safe to keep working with the units you like.
It is just a reminder that ‘1000’ in Grasshopper means ‘1’ in Revit.
