Looks good @jeff ! I actually implemented this also using a point cloud approach for a grid option in a plugin I’m creating for Rhino but I was not able to set the PointStyle to anything other than square.
Every other option simply did not work. Did you do something special here to have the dots show up as circles/dots?
Here was the bug/post about it:
If point cloud style can be set to dot now and that’s fixed, that would be amazing!
