(Rookie) Pls HELP! are we using Rhino correctly for what we are trying to achieve

Hi Kylie,
These are all very valid questions!

@CraftCoverings

now we use smash

I think for that, this is a good read:

Differnce between unrollsrf command and smash command

UnrollSrf is for surfaces curved in one direction, i.e. developable. Smash will flatten a surface that has curvature in two directions but this implies some expansion or contraction in areas so it’s not as exact. Here’s some further info on the help pages for these commands. http://docs.mcneel.com/rhino/5/help/en-us/commands/unrollsrf.htm http://docs.mcneel.com/rhino/5/help/en-us/commands/smash.htm

Note that smash is not all that reliable for flattening surfaces.

In any case, double curves surfaces will not be possible to convert in accurate 2D patterns without deviations.

Can you share ( a model or picture of) the type of surfaces you are trying to flatten?
