I came back to my computer like 2 hours later and the STL loaded things were there.. 


this was not my experience the first time it loaded it worked just as expected.


if I try to open another file it seems to just hang up and sit there as well..

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
