Hi everybody !

I have used grasshopper for few years, and I don't reach to understand the basics of the geometry gym for SAP2000 components.

Does somebody have a small tuto or a video to help me to understand how I can export my rhino model to SAP2000 ?

Hi Jon,

hope you are well, I have been thinking on testing how to export parametric models into Revit and I was wondering if I need to install your other IFC plugins in addition to " + REVIT/VASARI 64 Bit Installers, contact me for 32 Bit?

ok, found the problem: the tolerances in my rhino ducument were too low....

Comment by horst Becker on March 19, 2014 at 3:39am
I run into a problem trying to import profiles with the ggCatalogueProfil Component.
I save my user profiles in the right direction. Usually it works very well, but now I have the problems that I cannot load the open surfaces as a brep...I just get the outline curves of my profiles.
any idea?
And second question: is it possible to import differnt profiles which share the same 0 Coordinate. That after loading them into my definition they share the same insert point?

Thank you Jon for your response. I did the same.

Comment by Jon Mirtschin on February 25, 2014 at 2:20pm

Hi Mona,

If you look at the dome in elevation, you can see splitting into a hemisphere won't get you integral shapes.  If you can split above or below (as indicated on attached image) shapes will be rational but some will be halved.  Not sure if this helps or not.

Hi There,

Does anybody know that how I can have geodesic dome? I used StrucDrawRhino but it always gives me the sphere and if i cut it from middle of the sphere (to get dome) all of my hexagons in the middle will split randomly and they don't have the specific size . I want to have exact geodesic DOME (not sphere) with the exact same size of hexagons. I want to 3d print it and I really do not want to have many different sizes of hexagon . I want minimize the variation by using one type of hexagon and one type of pentagon or just one hexagon or 2 different types of hexagon. I am attaching the sphere and dome image to this post. as you can see in the image in the dome one the hexagons are cut randomly. I am wondering if there is a way that the hexagon can start exactly from the bottom of the dome.

I really need it for my school project and I will appreciate  quick responses.
