Fusion 360 DXF Export
When designing laser cut projects in Autodesk Fusion360 the easiest file format to export is dxf. But to do this for laser we will need to make a special sketch and export that.
Finish your part and save your file.
New Sketch for export
Start new sketch
and select the top surface of the part
When we select the top surface of the part you'll notice that all the connected features highlight. These are automatically projected and their outlines will automatically get added to the sketch.
We will need to add the eye of the dragon and the inner features of the "g" and "B" from the part. To do this start the Project tool from the Create menu.
Select the islands in the part and hit ok on the project menu and Finish Sketch.
Check the sketch
Once you finish the sketch it will be active so you can see the contents. I like to turn off the bodies I drew it on so I can see that all the geometry is there.
Save as DXF
To export the the sketch, Right Click on the sketch you created in the model tree and click "Save as DXF"
Check Drawing in LightBurn
Open up LightBurn with a new file and Click Import
This will bring the .DXF file into LightBurn and the contents will be fully selected automatically.
Checking for Errors or Duplicates
Occasionally you can create duplicate lines using the project tool in Fusion360. To check for this, while the entire drawing is selected, Ungroup the drawing and use the "Delete Duplicates" tool in the Edit Menu
Your drawing is ready to use
