OpenSCAD: Sneaky handy tricks.

[Mr_Sheesh]

Offering one - Asking for 2 more LOL

Partial one as a bonus - I use function i2mm(I) = I * 25.4; in must of my scripts, handles inches to mm conversions for me.

For hexagons like a hexagonal button, use cylinder() with $fn set to 6, you could use $fn set to 8 for octagons etc., devious but works

The two I need help on, are,

a) How would I place hexagonal buttons in regular, offset rows/columns efficiently?

b) For making a floor have alternating color tiles (or the like) I know I could add x and y together, mod 2 if needed, then if even (or 0) pick one tile color, otherwise the other; is there a better way?

Thanks, all
