if you want to slice your stl and use openscad to export them to a dxf format
then try this workflow
- in Autodesk Meshmixer, go to Edit-> Align and select Type:AAbox
- in Meshmixer go to Edit-> Make slices and select Method:Stacked 3D
- in Meshmixer, select each slice and click Edit-> Make solid
- Export each slice that has been converted to a solid as an stl file
(layer1_solid.stl, layer2_solid.stl, etc.)
- In openscad, import your stl
- use the following code
projection(cut=true)
translate([0,0,-z)
import("yourstl.stl");
Your z will be dependent on your stl file. To the best of my knowledge,
there is no module that will give you the origin of the stl file or place it
at the origin. I just experimented with different values. I believe aligning
the stl in Meshmixer will place the bottom of your stl at [0,0,0]
- export to DXF!
The tricky part is that you can't iterate the process with a for loop.
Others have suggested running shell commands but my stl was small enough
where I could just do it manually.
There might be a better way to do this but this worked for me. Cheers
