Improve revit import

[samPT7WG]

Specifically the issue where a revit model from an older version needs to be "upgraded" before importing - this adds a significant amount of time onto the import process, especially if the architects don't give any indication as to which 3D view should be used.

It would also be fantastic if there was a "whole model" option instead of picking a specific 3D view that may or may not include important elements.

there should also be options to import differently by revit category, I dont know how other people like their revit files imported, but for my personal preference, I import the model 2-3 times, isolating different categories to import them in different ways depending on the model.

eg if we could set up a single import profile that automatically  imported Walls as a single mesh, railings split by type, doors and windows as individual objects (which would be nice if they could import as instances, instead of unique meshes). As well as the option to not import certain categories in max, rather than having to go into revit set up a view, and import. 

It would also be nice if we could get the splines/paths for any railings as the ones in revit are pretty bad and we often replace them with a higher quality mesh or the architect has just used the "default" style and doesnt actually want that, its a pain to have to redraw all of the paths!

In addition it would be nice if curved geometry importing could be improved, it always generates something thats better off being remodelled, unless you want a 1gb max file!.
