Hello,

First, sorry , I am convinced that this question has been asked . I have a lack of vocabulary to find answer to my question .

Let me explain: on Sketch-up , I've made plans for a dinghy destined to be made ​​from sheets of material ( let's take a thin plywood for example) assembled together . They have some voluntary deformations to obtain the desired final shape and curve.

So, in Sketch-up , I have my modeling made ​​of curved surfaces .
How to get the cuts needed to be made to the original material , so a flat one ?
I guess I need a specific plugin. If so, which , and how to use it ?

Thank you in advance for your answer !
