3ds Max to AutoCAD Conversion

I have a set of 3ds Max architectural files that must be translated into fully-functional AutoCAD drawings without a single missing line or geometry error. Every element of the original model—not just floor plans but the entire 3D architecture, including walls, roofs, openings, and custom components—needs to arrive in AutoCAD 2018-or-newer ready for immediate editing.

You will receive the native .max files along with any linked textures or external references. Your task is to:

• Open or re-link all assets in 3ds Max, resolve any missing references, and clean up the scene so nothing is lost in translation.
• Export or rebuild the full 3D architectural model in DWG/DXF, preserving layer structure, object names, and world coordinates.
• Verify that the resulting file opens in AutoCAD 2018+ with no proxy warnings, flipped normals, or corrupted solids.

I will check the deliverable by orbiting through the model, slicing random sections, and running an audit in AutoCAD. If the audit reports zero errors and all geometry is editable, the milestone is approved.

Please outline your approach (e.g., built-in exporters, DWG TrueView verification, Revit/FBX intermediates, etc.) and estimate your turnaround time for the first file so we can keep the schedule tight.
