I converted the STL file through an online converter https://www.cadforum.cz/catalog_en/stl2dwg.asp

(I work in the program autocad 2017) Now I open the resulting DXF and I don’t know how to work with it. How do I merge polygons into a whole model?

  • $\begingroup$ What are you trying to achieve? STL is a model defined by its surfaces and ca be properly converted to AutoCAD if done right. laserscanning-europe.com/en/laserscanning-forum/… Or you use the right plugin: cadforum.cz/forum_en/… $\endgroup$

  • $\begingroup$ I do not know how to convert the resulting model into the body. For this reason, I can not do anything with the model in the autocad. I usually created my own models, and it was easy, but for the first time I was faced with converting and editing STL. $\endgroup$ Jul 30, 2019 at 19:39
  • $\begingroup$ What is your end goal? To bring an existing STL into Autocad to edit it? $\endgroup$

I figured it out. Need to go: Network -> conversion to surface

Then we get a surface that is already easy to work with.

    $\begingroup$ I edit the STL and dxf with Sketchup, the STL to change any 3D surface and DXF to convert 2D to 3D printables. $\endgroup$ Jul 31, 2019 at 21:17
