Hi i am Umo by name, a Masters research student of architecture in Nigeria....I am working on a thesis dissertation: Enhancing Visitor's circulation in arts and culture museum using the theory of space syntax (i have it in mind to use your syntactic plugin for Grasshopper )....Please i will greatly appreciate if you explain to me the steps i should follow to achieve the desired result of enhancing circulation using the above named software

I would love to also believe that there are tutorial videos or reference materials that will serve as a guide to carry out the necessary analysis and computations. If there are, please i would love to have the links that i can use to download them as these will tremendously aid the success of the research exercise...........Thank you so much as i anticipate your candid response

you can reach me on my private mailbox

Once again i say thank you

as far as I know According to the functionality of this component does not seem to be able to provide the mean depth.

If possible further advice Thank you.

Hi pirouz,

I'm bahador rahmat. I have a gha. file and a rhino file from one of your projects named city maker. I think it was a project with prof  José Nuno Beirão. I can't set levels and floors at that grasshopper code, I've set the area and have this picture!

mesh quad surfaces

Here is a component I have made for obtaining a set of almost planar surfaces for approximating a NURBS surface. This components converts mesh quad surfaces into a set of individual NURBS surfaces. If you want to use this component for manufacturing a double curved surface; you need to check the maximum deviation of quads from planar status and see if you and your manufacturing technology can tolerate this much error. Enjoy.
