The file I’m using for an example is larger than the 4M limit here, here is the link to Terrain2STL.
I’m looking for an easy way to get a 2D slice out of the 3D STL. There are so many STLs around for 3D printing, and my current project is a lake outline from an STL created with Terrain2STL. Ideally, I could specify which slice, so I can adjust the edge profile without a ton of vector editing.
I found Slic3r. That will export a DXF (or maybe an SVG ) from an STL since it uses that system to do 3D printing. However, I found that the slices are stored sequentially in the resulting file with no obvious way to choose one.
Then Will suggested OpenSCAD would squeeze out a 2D slice, but I’m a bit rusty with that.
