Hi, ive been recently working with grasshopper and one of the steps of the algorithm i was making, was to project some curves over a surface but i hardly make it work wright, it took me a lot of work to barely make it work well. Then i got an idea what if i make that step in MoI and i did it and it worked very very well from the first time. My doubt is, why that happened? is MoI using a different library than rhino?

Hi Ed, yeah MoI does use a completely different geometry library than Rhino. Even though MoI uses the same 3DM file format, that's just for storing the model on disk, not for calculations that happen at model time.

So the only part that is the same between MoI and Rhino is the 3DM file reading/writing library (which is called OpenNURBS), the actual modeling kernels are different.

Usually though I would not think that projection would be a problem in Rhino. It may be something that they can fix up if you can send them an example that does not work.

But anyway, I'm glad that MoI was able to help you complete your task!

Thanks for the explanation and Yeah! MoI rocks!
