HI TIG,
Thanks for your answer! usually i also work in the way that you explain, but in this specific case i need to try to make a structure like the one i attach on the post.
Anyway if there was a possibility to choose how the 2 facade can connect it will be very interesting....
Also I discover a plugin for help with the curtain wall http://pingpinkstudio.weebly.com but they not sell and also is impossible to find to download some demo o freeware, it's a kind of experiment. You think is possible to improve the lattice maker with the function of choose how the facade connect?
Thanks a lot for your help.
