About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
I use Archicad to model then export as 3ds. into 3ds max. then select "material" from options & set drawing unit 1000mm.
In 3ds max, when i import 3ds file it become tiny object. dont know what is that.
I am just guessing but maybe you should set the drawing unit to 10000 or 100000 and try it that way. So if it becomes tiny, blow it up to the proper size.

When I export to Max via 3ds I set units to 1mm and have no problem with objects coming in at correct scale, you appear to be scaling the model down to 1/1000th of its size.
See how you go with units set to 1mm, best of luck.
