Hi,
I`d like to draw a geodesic dome according to Paul Robinsons tutorials he made for sketchup I would like to use Paul method to construct an Icosahedron as base and then develop v1, v2, v3 and so on geodesic dome. The link to Pauls YouTube channel is the following:
I appreciate your help in advance.
Thank you.
Stefan

I would start with creating an icosahedron (using the "polyhedron" tool: https://cad.onshape.com/documents/2c40f522f1b5a02f6ce9ce01/v/585e4b002529cb792b0466cf/e/ff4f6157c94f693e713e91d3)
then create the faces for one "section" and "transform pattern them using the faces of the isocahedron...

Here's a simple example:
The transform pattern was a bit tedious to setup... I'm sure there's a simpler way to do it...

Much easier using circular patterns:

Ok I'm a bit slow... A combination of transform pattern and circular pattern makes it pretty simple:

I also created a v2 version using a slightly different technique later:
