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.

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.

Hi1 Does anybody know how to create windows and doors simple and nice within GeomGymBIM environment?


Comment by Jon Mirtschin on October 12, 2013 at 3:58am

Hi Yuke,

If you send the email, I'll validate the license file (I work full time on the development and support of the tools, so a licensing system is in place).  

Jonathan, can you email me with a sample model so I can take a look at this?  It might be document tolerance coming into play.

Hi, Jon, I am a student learning grasshopper recently. Now I am trying to download the Geometry Gym but it asks me to email the administrator. Could you help me?

Comment by Jonathan Lynn on October 4, 2013 at 7:44am

Hey Jon

Im having a slight problem while playing with the Tesselation tool. when the size of tessellation is over about 3500 a object reference not set error occurs. The target brep is an untrimmed surface measuring 15000 by 100000 (mm) and the tessellation type is weaire phelan. Ive tried a fex different breps and all fail to create the tesselation. Any ideas on how to set up for larger tesselations.

Thank you.

Jonathan Lynn
