I have a rotation moulded kayak that I have drawn, and am in the process of drawing up the mould. I have successfully created the mould parts, however both of the mould halves are very chunky, and would be a huge waste of material. I am wanting to cut away most of the material so all I am left with is a 20mm thick mould in the profile of the core.
I have tried to shell the mould halves, but it will not let me go larger than 1mm with the thickness due to the shape of the kayak. I have also tried to create a surface, and thicken it, but get similar errors. Is there an easy way to achieve this? The kayak is very intricate, and it will take many hours to do this manually!
Any help would be very much apreciated!
