What size do you want your finished model? What material do you want to print it in?

Basically, Revit is giving you a bad model. I haven't worked with Revit, so I don't know if there's any way to fix these problems in the source model or not. Revit is leaving each triangular shape as an independent piece, and this is causing you trouble with interior faces that are not being removed.

1) In the .fabproject, you have two of the main body elements in this file causing every face to be duplicated. You need to remove one of them. (just use Delete in Netfabb)
2) Every triangular shape shares one or more faces with an adjacent triangle. You don't need all those inner faces.
3) At this time, the model has 1.2 million faces - which is quite close to (or over) Shapeways upper limit.
4) Your outer spine(s) have a large number of holes.
5) Your endcaps have no thickness. You need to fix those before you try uploading to Netfabb Cloud.
6) Because the ends are capped, you're going to be charged for the entire volume as "Machine Space" - which will dramatically increase the cost of this model.

I went thru these steps:
a) opened the item in Netfabb Basic
- applied the "close holes" modifier
- deleted the two end caps
- exported only one shell as a STL
b) opened the model in Meshlab and did a Quadric Edge Collapse Decimation to reduce the number of triangles
- make sure you select "preserve topology"
c) sent the file up thru Netfabb Cloud (https://netfabb.azurewebsites.net/) to reduce (some) of the co-incident faces.

Thank you for your time.

Revit uses components applied to a mass to create a curtain wall. In this case it was a twisted rectangle with a triangular pattern applied. Each triangle is a piece, so I don't think there is a way to make a clean .stl in this sense. What would you recommend for future massing?

I was looking for the end product to be 5-6 feet tall or 1" = 50'.

I am following your steps so far. I assume I will scale it in netfab?

You can use Netfabb to scale the model to the right size, but you have to worry about wall thickness.

3200' at 1"=50' (1:600) scale is going to be 1625mm tall. (64 inches) None of the Shapeways printers can print anything that long. Your closest choice is WSF which has a maximum of 600mm, meaning that you'd have to break your tower into three sections.

Even then, it's going to cost over $450.00 to print. Is that within your budget?

How can I break it into sections? Revit does not have a function to divide curtain walls or masses.

This is part of my masters thesis so while $450 is a lot of money printing will save me a great deal of time.
