Help needed with circular beams and 'free-form' shape.

[Anonymous]

Hello,

So I'm trying to create a steel structure (concept) that can be bent on plan (so it's basically stretchable)

A precedent to what I'm trying to create can be found here: Image

I've used OBJECTiVE for a less complicated form but it needs developing. I can't seem to find a way of altering the shape in plan whilst also retaining it's vertical height etc.

I've attached what I have already achieved, by using the regular profile and OBJECTiVE, but all the arcs need to be joined together (and the from needs changing) (Also, my file is extremely slow since placing these arcs, is there a way to speed it up?)

As you can see from the attachment below, in plan the existing arcs are straight lines at various angles. I want to be able to bend the profile in plan. (the height of each curve can be determined in elevation).

The beam and magic want do not work unfortunately. The profile needs to be able to "stretch"... I should also add that the total length of this singular piece of steel will be around 80 metres. (though I can cut it and join it together if there is a limit in terms of length.)

Thank You very much, Hopefully such a task can be carried out... ArchiCAD 15 looks like it can do this but my deadline is next week!

Have you tried the MEP Flexible Duct 14 ?

I've almost finished the project (2 days left so it's manic!) but I modelled it all with OBJECTiVE. I'll admit it was a long and slightly tedious task but it gave the best results...

I always forget about the MEP modeller, perhaps I could have a go after I finish uni.

Thanks anyway
