Extract Flat

I’ve been watching tutorials and it shows extract Flat for making patterns. I have ver 6.18 and I do not have any of those tools or options in the Rhino Options. Can you tell me how to flatten a 3-D object or direct me to a tutorial of how to o it with my version?

Hello - the tools in Rhino are
UnrollSrf for developable surfaces
Squish for surfaces with compound curvature. This is not as sophistcated as Exact Flat by any means,

-Pascal

Are here any good tutorials for it. Every time I use those tools I get some pretty bad results unlike what I saw with extract Flat?

It would maybe help if you would post the tutorials you’ve seen where they use extract flat?
