Hi, I tried some boolean commands(difference, intersect, or trim) through grasshopper and rhino(V5) and found that in some cases the results are different. Usually the results from grasshopper are…Continue

Hey Sangsu,  It's me again....I was wondering if you can help me with some advice regarding the export of towers from GH to SAP2000? Maybe if you'll have a little example to see how did you managed to do the tower from the posted…

Hard one....   Well it would be nice if you could use the components that already exist...Here a sample for the coupling prozess that I would imagin for the longest path def I wrote.   Please not in order to use the definition there have…

Would it be possible to set up a series of goals to be handled by Galapagos, in a succession?   First solve this (reach at least this fittnes value). ...then solve this (and lock the values from the first step) and so on This would…

Hi Richard,   I am planning to add a special Galapagos number generator to replace a large (or even variable) amount of sliders.   I'm not quite sure what you're asking for with your second request. What do you imagine the…

To Sencu Razvan, Maybe you can save Rhino model as Igs(Lusas type), and import igs file to sap2k, try it!

Are you creating voronoi in 2d then box morphing it to the surface?

Thanks for the quick reply, I guess I'm still trying to figure out how to convert the mesh into area objects. When you have it as a mesh in rhino, do you save it as a dxf and them import it into SAP? Is there a special setting for the mesh to be recognized, I import the layer as a shell element? Basically each time I try, I get a blank screen, nothing manages to import.

Hi sangsu, i saw your posts and I'm very impressed. I wanted to ask you how you could transfer rhino surfaces to SAP2000? I am trying a similar process but cannot seem to get it.

Thanks
