Is there a way to pass objects back and forth from Autocad to Daz?

I was wondering if there is a prefered format for this...

    Why not FBX?

    The FBX import function for Daz Studio is useless in my experience. Desides, you would have to rerig it to DS format if you did manage to get it imported.

    According to Autodesk, these are the formats available for export

    Format Description Related command In AutoCAD LT?
    3D DWF (*.dwf) 3D DWFx (*.dwfx) Autodesk Design Web Format 3DDWF No
    ACIS (*.sat) ACIS solid object file ACISOUT No
    Bitmap (*.bmp) Device-independent bitmap file BMPOUT Yes
    Block (*.dwg) Drawing file WBLOCK Yes
    DXX Extract (*.dxx) Attribute extract DXF™ file ATTEXT No
    Encapsulated PS (*.eps) Encapsulated PostScript file PSOUT Yes
    IGES (*.iges; *.igs) IGES files IGESEXPORT No
    Lithography (*.stl) Solid object stereolithography file STLOUT No
    Metafile (*.wmf) Microsoft Windows ® Metafile WMFOUT Yes
    V7 DGN (*.dgn) MicroStation DGN file DGNEXPORT Yes
    V8 DGN (*.dgn) MicroStation DGN file DGNEXPORT Yes

     

     

    Using Siemens NX, the only way that worked well is Lithography (STL).  DXF introduces all sorts of surface distortions.  Step 3 is necessary for some reason if you plan to assign a material where you want to see a textured surface and be able to adjust the horizontal and vertical scaling of it and the bump height as well.  

    1. Export it as an STL
    2. Import it into Blender and Convert it to an OBJ
    3. Open the OBJ with Sketchup and assign any material to it and export it again as an OBJ
    4. Import into Daz

    If you don't have an armarture, why would you prefer FBX anyway? Wavefront OBJs are simple and well supported by everry application. It won't preserve your materials beyond diffuse maps, but chances are you'll want to re-texture everything with Blender's material node system, anyway.

    On the other hand, I've have precisely ZERO luck importing all but the simplest FBXs into Daz.

    Why use SketchUp to do the materials when you can dothem rightin Blender?

    Use FBX because, and this may be a surprise to everyone, THERE'S NO OBJ FORMAT IN AUTOCAD.

    I'm serious, OBJ is NOT supported by AutoCAD, you HAVE to use FBX.

    This is a bit of a necro thread.

    I did write a routine for my modeller that read AutoCAD 2000 .dxf 3DFace objects and read them as .obj facets. The 3DFace Dxf entity always has 4 corners defined, with the corner points being the equivalent of vertices. If corners 1 & 4 are the same, then the face is triangular, otherwise it's quadrilateral. Later versions of the .dxf format have many complex surface definitions, many of which are not readily compatible with DS. STL is probably one of the better formats to use, simple & doesn't change with every version of a program (unlike .dwg, .dxf etc.). This is a very useful resource: https://paulbourke.net/dataformats/
