Imagine a football sliced in half, lets say wall thickness 5mm and a need to scale it larger, is there no command that can be applied , keeping the wall thickness same ?
Likewise a non compound curved object ?
Likewise a box shape, alter size keeping wall thickness same ?
Is grasshopper the only way for what appears a simple command ?
One day I might get time to learn grasshopper but I have a backlog of tasks and need to rescale such objects.
