I just saw a very simple design explode to 27MB and would like to understand why. It's a simple injection molded plastic spacer. Flat rectangular extrusion, about 0.150in thick, 2 in x 14 in. About sixty holes. Rounded rectangles. Point driven pattern with sketch located in a different part file. Shelled to 0.050in A dozen ribs added. Drafted to 1 degree. That's it. 27MB. I used Ecosqueeze and got it down to 13MB. Still, how is this possible? -Martin
