Originally created in Rhino6, I need to create with Grasshopper, however I’m not sure if any aspect of it can be done.
I have up to step four but i cannot find a way to rotate without overlapping the pattern?
Yes, there is a way. But you’re not giving any information on what exactly needs to be done using grasshopper and which parameters you want to control. Have you tried anything yourself? Just start by trying to create your triangle and work your way through automating the different steps described in your image. It’s usually easier to get help here if you ask about a specific problem you’re stuck with.
