Yes, it does! All of Axiom's software for Autodesk base applications (for example, AutoCAD and Civil 3D) works in 32-bit and 64-bit versions of your supported Autodesk software. For each Axiom software product, there's just one file to download, no matter which version of AutoCAD (32-bit or 64-bit) you use. The Axiom setup program will install the correct version (32-bit or 64-bit) of your Axiom software automatically.
