Convert to parts error: Can't make parts out of these Elements

[semi]

Hi everyone,

I have a major problem with my revit model and I hope someone can help me out.

When I schedule system families to Excel for a cost calculation, I always turn them into parts so I can make a material take-off from those parts. The reason for this: it's more accurate and I can combine floor parts with wall parts together for some schedules (for instance elevator walls and floors go into one schedule in our country calculations).

Second and more important reason for this is to filter all my walls by base constraints, so the contractor can find our on what level my walls are located and where to look.

Lastly I can show the thickness, height and correct length of these wall parts into this same schedule.

Example

Parts schedules of elevator walls (foundations) and its floor slab:

Result in Excel:

Now this entire workflow doesn't work when Parts can't be created.

This happened when I got this error: Can't make parts out of these Elements.

Solution from Autodesk: remake the walls...

I can't do this for 1000 walls in a project. 

Any solution for this?

Let's take a look at the RVT.  Post it here.  You might want to Group only the pertinent elements together and Save that Group to RVT - then post that RVT here instead of the whole shebang.

Do you have any complex or curved voids cutting the walls?

The model itself wasnt build by me, so I have no correct way of knowing why or how, but a wall that causes this error mostly consists of openings made by a window family in addition with a curtain wall and it's attached to a complex roof.

But still this shouldn't be an issue to create parts imo. 

Selecting all the walls in this model and creating parts of it does not even give the error in Revit. It just makes parts from the walls that do get to be parts, but the walls who are to complex to make parts of just ignore the command and stays "partless" without any error.

This compounding complexity is exactly why Revit cannot create parts from such walls.  Can you select one of the walls in 3D, isolate it and share a screen shot?

Revit does normally give a warning when it cannot create parts, but the warning may not be too obvious on the screen, especially if you use more than one monitors.
