How to model semi-spherical shapes in Revit 2023 Analytical?

[allan9pires]

Hello, everyone! 

I'm trying to analyse a structure that has two semi-spherical shapes in it (pictures below), and i'm having trouble modeling the analytical part of said shapes. The Analytical Automation command does not work at all with these shapes (and has not been working consistently with this structure).

Shape 1 - isolated view

Shape 2 - isolated view

I can't seem to be able to pick the concave "workplane" (it's not a plane, so i guess that's why) of those shapes, so i cant make a panel out of it. Also, whenever i try to use analytical arc bars, they turn to straight bars when i integrate with Robot Structural Analysis.

Also, these shapes were modeled with the help of masses.

What is the best way to analyse this with Revit and Robot?

Any help would be really appreciatted. 

Thanks in advance!!

Hi @allan9pires ,

Revit analytical panel don't support (at least not yet) 3D panels. Only curved/cylindrical surface.

So, from my point of view, there are two options:

- either in Revit you create a mesh of (planar) panels to describe that 3D curved area

- either you model it directly in the structural analysis solution (I don't know if Robot handles those surfaces)

Thank you so much for the response! 

Could you please recommend the best or quickest way to create that mesh on revit?

I would say some automation tool, maybe Dynamo based. 

The current analytical panel use reference planes as support. To create such a surface manually, you will need to create several well determined reference planes, which is not an easy task at all.

i see! i'll look into it then!
thank you so much for taking the time to answer me!
have a nice one!
