Hello there. I was searching how to unfold sheet metal parts similar way. The problem I found that if you unfold along outer circumference means you are adding the thickness to the dimensions of the component end there will be an length/width will be long by thickness of material. Shouldn’t it be folded along the inner circumference. Have you found a solution to get the accuracy right, like in Solidworks? Did you come across any other extension which gives more accuracy?
