Bothe settings is set at mm units. How to fix this?

Hi Eric,

The dwg file needs to have MEASUREMENT set to 1 in AutoCAD. If not, the file unit can be inconsistent. Open the dwg file in AutoCAD and set MEASUREMENT to 1 and save. After that, the unit will be persistent.

Many thanks!

Hi Johnsonsiue,

I found the error. It is by creating a WBLOCK that the units are set to inch by default. Have this now set to mm and then the WBLOCK will be transformed the drawing to mm and the inport in Inventor is correct in mm. Think many users overlook this setting. Thank you for your response!
