    @Max, will the mass fix be installed with the v22 update if I allow Alibre Design to update when I start up? (I've been having it "remind me tomorrow" until the mass fix was made). Thanks!

    +1. I personally prefer scientific notation, but I can see why it might be counterintuitive as well.

    Please Max, can you post a copy of that assembly? :p:D

    The mass fix is in build 22053, which is available now if you just let it update at start up.

    I'm not Max but here is one of mine. The part is completely centered on the origin - but look at the results.

    Code:
    Design summary
     Parts : 1
     Faces : 6
     Edges : 12
     Vertices : 8
     Unique parts : 1
    ===========================
    Volume = 9E1 in³
    Mass = 2.546852942E1 lbm
    
    Center of Mass = [ -9.955841225E-16 in, 2.427855290E-16 in, 0 in ]
    
    Surface Area = 1.260000000E2 in²
    
    Mass moments of inertia =
    xx:7.216083337E1 in²·lbm yy:9.550698534E1 in²·lbm zz:1.294650246E2 in²·lbm
    yz:2.434405665E-15 in²·lbm zx: 0 xy:4.868811331E-15 in²·lbm
    
    Principal Axes and Moments of inertia =
          7.216083337E1 in²·lbm  {1,  0,  0}
          9.550698534E1 in²·lbm  { 0, 1,  0}
          1.294650246E2 in²·lbm  { 0,  0, 1}
    
    
    Accuracy:High
