Has anyone fully modelled a 35-to-100 story curtainwall building using Revit?

If so, please respond.

If not, do you believe it can be done?

Over.

I hear that freedom tower is pretty tall.

Yes!

Over. kshhhhhht.

Ok,

Based on some other user's comments, it sounds like workgroups may be the key to modelling extremely tall buildings in Revit.

Also, our product distributors mentioned that SOM has divided the "Freedom Tower" into multiple models. Supposedly these get connected up in a master file.

I tried to model a 35-story curtain wall using copied groups. The skin was grouped either by floors, or by halves.

In each case, I crashed the computer.

[Scott D Davis]

did you create a support request to find out why the program crashed?

Was the curtain wall of the freedom tower made with the curtain wall tool, a complete custom made curtain wall family or a generic family embedded in a curtain wall panel?

Also, do you have any reference of the main building when you work separately on a curtain wall in a separate file?

Yes, you can link the struct system and the core files into the curtain wall model. There curtain wall was actually made of a generic model family with parameters to control and study the shape.

I think families will be better for taller towers, the curtain wall tool is great but can get sluggish. For anything that repeats multiple times families seem easier to work with and assemble.

The Freedom Tower curtain wall was (I believe) a series of custom-made generic model families...

I worked on the basements (all 64 acres of them). If you've seen ground zero, you know what I am talking about. That whole hole has to be filled. Never got my head above ground, so I can't tell you about the exterior wall. James V. or Phil R. know more about that. There were lots of modelling innovations.

We started out with the entire building in one model, but we had so many on the team that STC became an issue. We finally did split it up for that reason. Remember, we started on 6.0

We are starting another massive tower in Korea, so I would say that our senior management are impressed enough with the Freedom tower experience that they are willing to commit to another
major project with Revit .

By the way, we have some smaller projects in Revit too.

I will add that the "massive tower in Korea" Mike refers to is slated to be the second tallest in the world, and it's geometry is at least as complicated as the original freedom tower design. It's currently using several instances of a complex family driven by even more complex formulas, to create it's "curtain wall"
