There is no material at all in this FBX file… Blender creates a default one, cannot do anything else.

This is not true, when I try to open it in 3DS MAX, there are materials. See attached screenshot.

How can I reopen this task? Or should I create new one?

It is probably related to this:

http://blenderartists.org/forum/showthread.php?311346-Preserving-Materials-when-going-from-Revit-to-Blender

When I convert material in 3DS MAX with script from that thread and export FBX from MAX, materials are imported fine.

That’s Revit problem, they have to export valid 'usable' FBX materials - if they stick to their utmost cryptic own cooked custom ADSKAssetReferences and other ObjectMetaData stuff, there is nothing we can do - Blender's FBX importer does not and never will aim at supporting all possible fancy non-standard stuff from FBX, supporting basic ground features is already an epic PITA…
