  1. Thanks Frank, It is still giving me wonky numbers for Mass Moments of Inertia (x,y,z) that are not even close to what it should be. Even MMoI for a sphere are incorrect. The numbers are all the same, which is right, but the the numbers are incorrect. It seems like I have tried everything! I appreciate your input.
  2. I am having a hard time trying to retrieve the 3D properties for a simple extruded rectangle. In particular, I am trying to find the MMoI (Mass Moments of Inertia) for it. I am using this simple shape as a test to determine if the VW calculations coincide with my calculations before I move on to the actual more complicated parts that we need this information for in order to run our simulation software. At this point the MMoI does not match my calculations. In design layer, I placed the origin at the CoM (Center of Mass) using "next mouse click is zero (0,0)" in the set origin command. Any tips? -please see attached
  3. Thanks Raymond! Now that I have delved into it a little more, I am having a hard time trying to retrieve the 3D properties for a simple extruded rectangle.

  4. Can anyone suggest a good stl viewer that can be downloaded from the web? Thanks,
  5. Hi, I am trying to set the origin in a 3D drawing to a midpoint on the bottom of what basically represents a steel bar which is 1/4" thick x 1.5" long x 3/8" wide. When I get the 3D properties for center of mass Cx, Cy & Cz seem to be wonky numbers. Center of Mass: cX: 3.644e-018 in cY: -0.7500 in cZ: 0.1250 in Any thoughts would be appreciated. Thanks,
  6. Can someone tell me how to calculate the weigh of a part that I have designed to be machined from 1018 carbon steel? The following is what I know: Volume = 0.662 cu.in. Density of 1018 Carbon Steel = 0.283 lb/cu.in. mass = volume/density weight = (mass) (gravity) Thank you,
  7. Does anyone know if there is a fast and easy way to view an .stp file?
  8. Hello everyone, I was wondering if anyone could tell me if this graphics card is sufficient to run VW2012?
