Import 3d path from another program

[johnaboiles]

I'm trying to import 3d contours generated from some software I'm writing and generating a 3d model from it. Is there a file format that can be used to import 3d paths?

I've tried importing an .obj file that just contains edges but nothing shows up. I suppose I could make some fake faces along the edge and just delete them, but it doesn't seem very streamlined.

If this is possible with a simple file format, I wonder if there's a way I could write a plugin to import a 3d path. Any guidance would be super helpful!

Hi,

First you should have a look at the import formats for each license type and then clarify which one is suitable.

I've looked through those, cutting out the proprietary Autodesk/Solidworks/etc ones I won't be able to add to my program I see

• DXF Files (*.dxf)
• FBX (*.fbx)
• IGES (*ige, *iges, *igs)
• NX (*prt)
• OBJ (*.obj)
• SAT/SMT Files (*.sab, *.sat, *.smb, *.smt)
• STEP Files (*.ste, *.step, *.step STL Files (*.stl)

I tried an OBJ file with a line but it wouldn't import the lines -- just the faces. I could potentially brute force and try every single one, but was hoping someone would have some experience.

Edit: I started going down the list and I think I'll be able to get DXF to work in 3d, though it's a really hard format to read. At least it's plain text though!

Dwg and DXF will import 3d curves but you will need to use the online translator not Insert DXF for DXF. If you have a commercial licence you need to use Upload in the data panel with DXF files, if you use Open the local translator is used and last time I tried 3d curves where ignored. Not sure if you can upload DXF files through the data panel with a personal license.
