Hi Hetal,

LabVIEW does offer an ActiveX interface but you will need to look into AutoCAD's interface for more information.  It may be simpler for you to use the 3D Picture.  Most CAD software allows you to save as a VRML or STL.  Please take a look at the following links:

You might be able to use .NET codes inside labview.

I installed DWGTrueView and it creates an item under the Labview Activex control Create Document.

Had to change the labview background color. Here is an image of a dwg file inside the activex control.

Hi Hetal,

You mentioned that your software does not support wrl.  What about stl and vrml? 

Please include error handling in your VI.  Are you getting any errors?

Please post your VI and dwg.
