Hi

I will be making mainly Guitar parts, Nuts (This is what the strings lay over were the tuning pegs are), Saddles )This is what the strings lay over the opposite end of the Nut)& Bridge pins (These are what hold the strings in an acoustic guitar) also be inlaying guitar fretboards and Headstocks with Abalone and M.O.P.

I suspect these are 3d profiles.

My apologies if you know these terms.

What is 2.5d?
