Hi all: I am new to 3D Design/Printing and have been kicking around the Shapeways site. The information is very interesting and I found my way to the tutorials section, but there does not seem to be any kind of a starter guide. I am a software developer by trade, and have always learned new topics with "Hello World" type tutorials, which take folks through a simple project from start to finish. Does anyone know if there is a step-by-step "Hello World" for 3D printing that starts with what 3D design software to use, designing a simple object, and then actually getting that object printed? Thanks in advance for any and all help. John.
