Triangular window challenge

by Julie

Nov 7, 2017

Hello.. I need help figuring out how to make a script for window mullions that can follow a radial attractor point so that i forms sort of concentric triangles . see attached screen shot as an example of what I am trying to achieve. I would also like to be able to specify the mullion size/ thickness (eg. 4x4)

Anyone who can give it a shot and let me know what they can suggest would be a LIFESAVER!

Thanks,

Julie

    Hello,

    what you want is not very clear. What have you now ? A mesh where each triangle will be a window ? A surface ? ...

    I have done something similar but not exactly :

      Your surfaces are portion of revolved surfaces. So search the centers, draw the surfaces and apply a triangulated pattern. 

      Here a beginning of solution,Need Lunchbox for triangles.

        I did a script to cut holes. It offset extrudes the triangles from Lunchbox and then cut the surfaces and then connect edges with loft. So at the end you will have a solid. I am sure there are many of this type of script on the forum. The only problem is for triangle glass which are often flat there will be no continuity with the shape. It is also possible to bevel the holes using 4 surfaces instead of 2 and using 2 cutting shape instead of 1. 

        You will need Clipper because Rhino offset is not good enough for the job !

        It has been done in Rhino 6 so there could be some compatibility problem. I test it now.
