I noticed something peculiar about importing CAD drawings.  It doesn't appear that you can select what CAD paper space view or model space view to import from, so I thought it would default to model space every time I bring it into Revit.  However, depending on the desired Revit plan view, the imported CAD file's default view will be different.  Some Revit views only import paper space, while other views only import paper space.  What controls this or is it completely random?  Is it based off of associated levels, view ranges, crop boundaries, or something?

Never just import a CAD drawing!  You should always clean them up first  (especially if exploded which has more issuses) and only include what you need and set your origin somewhere near your objects.  If you don't follow this advice there will be some real consequences down the road for you.

So if you do the above, you should only have one model space view.

Linked CAD is different and you do not have to clean it up.

I had tried cleaning it up as much as possible before importing it, but was only able to delete all but 1 model space view and 1 paper space view.  This may be due to using Microstation to edit the CAD file instead of AutoCAD (I come from an odd Microstation background).  I'll try stumbling through Autocad to remove the undesired paper space view if possible.

Unfortunately, this still does not solve the problem with linked files since there is no way to control which of the views will come into the Revit model.  I still get model view or paper space view as a hit-or-miss depending on the destination Revit view.  If I delete the paper space views from the linked model, then I would have to re-do it every time the consultant provides updated backgrounds.

Revit is a 3D program and basically it imports the model view always no matter what is in paper space.

Hi, I have encountered a weird problem were when importing a CAD file the only think that comes in is a title block from one of my layouts.  I thought revit always imported from model space. I am stumped as to how to fix this any help is appreciated. Thanks
