This is the part which I wish to make in Solidworks (as a single part, may contain multi-bodies), but I'm not really sure how to do it. From the picture attached, I can roughly break the steps down into 3 parts, namely:

1) First, to make the paraboloid, I can do this easily by drawing a y=x2 curve and doing a 360o revolve boss. No problems with that.

2) Next, to make the hexagonal surfaces which bulge out of the surface, I have some trouble over here. How do you do this? How do you stick the paraboloid to the centre of each hexagonal surface?

3) Lastly, how do you make patterns (replications) of each paraboloid on a hexagonal surface? Doesn't look like a linear pattern to me...[updated] tried all the patterns and fill pattern is the closest.

Hope someone may share some advice for me.

Thank you
