One consern when printing 3D models is that they excide the limits of the machine. They are automaticly scaled and very offten vital parts are missing. With these tool you can check area and volume of the model in the designing enviorment in relation to the machine limitations.
The elements work with any 3D model created or imported in Rhino/Grasshoper. Only limitation is thet for the area check you have to use box like objects.
The idea is, in the future to have the option of selecting areas/volumes of the most comonly used machines.
