software and how to design using it

[goney3]

I have used the flattening ruby script that Outersketcher posted... I designed a very nice Tommy Machine Gun using it for last years Halloween. Worked like a charm

i got a 3d model, my question is how to reduce and combine the part before i export it to pepakura or can i edit it in pepakura?

sorry for my bad english
