Sorry but I couldn't get that file to open in any software. Fusion or AutoCAD. What program are you using to create this DWG?
While Inventor Fusion for Mac allows the import or open of DWG data, not all DWG data is supported. DWG can be 2d or 3d. Fusion for Mac, and all the other Fusion products such as Fusion 360 (which also runs on Mac) fully support 3d DWG data only.
What is the expectation of Inventor Fusion for Mac in your workflow?
