Comvert Solid 3D bodies to .FBX with .NET

[eirij]

Hi,

Does any one know the way to convert Autocad Solid3D objects to .dbx format with .NET? Actually, what i am trying to do is moving solid3d objects from Civil3D drawing to Infraworks through .NET Api.

Best Regards,

If you haven't already, I'd suggest posting the AutoCAD .NET group.

As far as I know there is no exposed API function to export FBX files, but you could use the Editior.Command() method and call the  -FBXEXPORT command. Something like this:

ed.Command(".-FBXEXPORT", "s", solid.ObjectId, "", "s", "y", "n", "n", "n", "e", folderName + exportname + ".fbx");

Hasn't FBXEXPORT been removed from the product? At least in Civil 3D 2020 that appears to be the case, unless I'm missing an update.

That's true, FBX export has been removed since 2019 version. Very odd in my opinion, because FBX is a very useful format to transfer 3D models. 

The function I mentioned works fine in 2018 version.
