|Volume discrepancy question [message #55366] Mon, 15 October 2012 03:54 UTC
I modeled a multi-part model in Unigraphics, which can calculate the volume of your model. When I compare my calculated volume to the volume shown on Shapeways when I upload it, they're not the same. What am I missing? The volume shown on the site is like 18cc MORE than my calculated number.|
Here's the model: http://www.shapeways.com/model/737734/b0f0c61eb2857af67ad19c e4fafaa7e8
My calculated volume is: 198 cc
Shapeways volume shown online is: 216 cc
Why does it show more? I've got a lot of hollow volumes in it, but they've all got drain/access holes, so there's no captive holes. Any ideas?
Normally I wouldn't care too much about the volume, but this is a pretty big model and I was being very judicious with volume to keep cost down, but now it doesn't match my predictions, and it costs more than I expected.
