So a 100-unit cube in units of created in AutoCAD and loaded via DWG into Fusion 360 will be 100 mm in Fusion, a 100-unit cube in units of will be 1000 mm in Fusion. If you import a DWG file created in AutoCAD into Fusion 360, the unit settings from _UNITS or _-DWGUNITS are respected. When importing a DWG/ DXF file back into Fusion 360, the original size remains unchanged.

If you open a DWG or DXF file in another CAD application, the unit conversion may be affected by that application's unit settings. This will convert the document to centimeters, and a 1-inch edge will automatically convert to 2.54 centimeters, keeping its size unchanged. If you work in inches in Fusion 360, change the document units to centimeters before exporting. The specific physical units/size of these drawing units is only needed for dimensions and plotting ( _PLOT or layouts/paperspace). Remember that a DWG file uses dimensionless "drawing units" by default. If you are working in mm, convert the resulting AutoCAD file to mm by scaling it 10x ( _SCALE). DWG or DXF file exported to/from Fusion 360 has incorrect size (scale, 10x larger/smaller).Īutodesk Fusion 360 exports DWG and DXF files in centimeters (cm), similar to Inventor.
