Import file in 3DEC

hello everyone, after import geometry from AutoCAD there is no plot appear?

If you import a dxf, you need to plot geometry (in the list of plot items, it is under User Defined Data). 3DEC doesn’t support other formats (e.g. dwg). See here for more help with using geometries in 3DEC.

Only dxf format will be accepted, the best is to convert them in stl format.
