I've created my studio project using a blended sweep, so I have an irregular shaped building envelope. I would like to support that envelope with a truss system a-la free university of berlin (the picture of this is below). The trusses would wrap around this almost spherical building (but an irregular shape). Do you have any suggestions on how I could make those? Perhaps wrap a railing?

I have the same problem here. What is the solution to this? How can I make the truss having the same shape as the dome? I have attached a picture showing what I wanna do with the truss. Can anyone help me =) Thanks. I tried using the in-place model for the truss which extends down to the floor to support the dome. I have no luck getting it done...

You would have to build a truss family to that shape. For something as special as this, you can't expect to do it with "stock" items. Build 1/2 truss in a family with extruded or swepth forms. I would not try to make it parametric.

If the shape of the roof is more of an elipse instead of dome (maybe like a shape of a boat), then each truss surrounding its perimeters would have different shape of truss right? How do I determine the shape of it? Do I create a specific paramenters or do I have to create the different shapes of truss to fit the boat shape? Thanks =)

If each truss is unique, I would build them all in place. Set a ref-plane (work plane) and cut a section at each location. Then build your truss from the geometry that shows.

I've got an even more complex truss issue - I'm trying to create a triangular cross section space-frame/truss that curves in 2 directions... similar to the beams seen in the Dos Hermanas Velodrome roof. [ http://en.structurae.de/structures/data/index.cfm?id=s0010217 ] Is there an easy way to do this? I don't have time to create a unique family for each truss. I with there was a way to create a space frame from just a swept mass. thoughts?

do you ever use the conceptual massing tools? they would work great for this

Thanks. Yeah, I found a video tutorial on how to use reference points in the conceptual mass to create my truss elements as a series of sweeps along a zigzag.
