I got something. exporting dwg "as is for output" and then linking to 3ds max can work unless link preset is set to "color". Everything seems to work fine like 3ds export set to "material".
Link archicad model as dwg, apply materials,modifiers, then change archicad model and click reload. Link works!
I have an issue with some gdl parts like chairs.. they seem to have one color despite the different materials they made of.. i 'll keep searching..
