Hatching Geometry of large group

[memo_b (Mehmet)]

Hello all,

I can’t for the life of me figure out how to hatch this.

Original geometry is a circle, transformed a number of times, grouped, then transformed again.

I think I can hatch the original circle, then run all the transforms, but I’d like to learn how to hatch this output as well.

Any ideas?

explode the hatch pattern, they will become curves, but I guess it’s going to be SLOW

(in order to explode the first hatch, there’s a dedicated “explode” component in the new Rhino8 Grasshopper components)

Thanks inno. Yes, it gets super slow when you do it that way…

I decided to rebuild with hatch first, then other commands… that sped it up a bit.

Here is how such a thing is done with the tools available in the Rhino 9 WIP:

Sadly, hatches are limited to lines, no curves, so the pattern is an approximation of the circular form.

Of course you could attempt the same thing with real geometry in R8:

Some changes:

You’d have to make alterations so that the script works on a data set of closed curves, and can respond to rotation and offset wishes.
