explain a solid 3d

[antoniot_3_]

Good morning.

How can I explain in the floor a usual 3d with a certain curvature? I explain: I have a solid 3d ascribable to a sheet with a certain curvature. How can I make it flat without changing its size?

Hello antoniot_3_,
in catpart there is no concept of "development in plan", which I know.
In order to do what you ask, I recommend you to use a package "sheetmetal design", where there are special commands to develop sheet metal components in the plane taking into account the deformations.
Alternatively, if you don't have a "lamiera" package, but you have a "generative shape design" package (advanced surfaces) you can extrapolate a surface of your component (external or internal skin) and develop it on a floor with the appropriate "sleeping development" command of the "shape developed" toolbar. In this case you lose compensation for deformations.
