You can open a 3D file in Fusion to take advantage of the Shaper Utilities SVG exporting Add-In.
This saves a lot of hand manipulation and color-coding of 2D vector files.
Save the 3D file from whatever software package you work in. STEP is a good option.
- Click "File" > "Upload" and upload the desired file into Fusion
- Go back into "File" and "Open," navigate to the file, and open it
- Click "Utilities" to select an individual surface or the whole model
