Hi All,

The jpg is a test sample I drew up in Fusion 360, with the idea of creating a non slip surface for a step made of Al.

The problem is the only method I could think of to do this was creating a triangular extrude cut on two different faces of the block, and pattern that. But it was quite tedious to do, especially the second face having to select all the small triangular faces left by the first extrude. This block is only a couple of inches and had 40 + faces to select, my final design would be a 20" X 4" ellipse, so a heck of a lot of faces! And I am not even certain I could use this method with an ellipse.

I just think there has to be a better way to approach this, so if anyone has any suggestions, I would love to hear them.

This is the link f3d file.
