In this Grasshopper tutorial for beginners, we are going to model a parametric dome from a hemisphere by defining cutting curves. Free Example File/Cluster
In this Grasshopper example file, you can project a parametric star inside a polygon onto a hemisphere and convert it into a star-pattern-based dome. More info
In this tutorial, we will examine a Grasshopper script that can help you easily manipulate a box brick around a polygon by defining the segment count and number of rows. Free example file
