Constructing a 3D irregular solid

Hi all,

Im new to solidworks and i have some questions for you guys. Im trying to make a 3D irregular solid as the same type as the one in the picture bellow. I want to be able to create an original solid with faces as i see fit. I want to kown what's the best way to make this type of solid considering  that i will experiment on the patterns. After finishing, is it possible to dismount all the pieces from the solid to set measures and see all the angles between faces, and if so, how can i see that. At last can u guys tell me how can i create thickness in the solid.
