I need to QUICKLY create a hollow box entering w d and h in cm, then make the walls 3mm thick heading inwards from the initial box, and get volume of the walls only.
If I use the solid box tool then offset 3mm it wont let me have volume of just the walls .
what method should I use thats QUICK.
It is simply to estimate box weight for ebay, as making boxes up and weighing them for items that never sell is stupid !
I also add in the bubble wrap, so again placing a box within this and doing same to whatever thickness I require does for that !
