Hi All,
I hava Intellcad 4+ and I read somewhere in specs that it calculates SECOND MOMENT OF AREA.
1. Is this right?
2. If so what is the command?
Thank you in advance for any help.

ERIC,
The command "massprop" can be run on 3D Solids and will give the following information:
Mass: 125.2641
Volume: 125.2641
Bounding Box:
Lower Bound: X= 4.8769 Y= 2.5834 Z= 0.0000
Upper Bound: X= 7.3062 Y= 4.7319 Z= 24.0000
Centroid: X= 6.0916 Y= 3.6577 Z= 12.0000
Moments of inertia: X= 25774.7626 Y= 28760.4946 Z= 6433.8379
Products of inertia:
XY: 2791.0096
YZ: 5498.1218
ZX: 9156.6401
Radii of gyration: X= 14.3445 Y= 15.1525 Z= 7.1667
Principal moments and X-Y-Z directions about centroid:
I: 6060.8634 along X= 1.0000 Y= 0.0000 Z= 0.0000
J: 6074.2803 along X= 0.0000 Y= 1.0000 Z= 0.0000
K: 109.7889 along X= 0.0000 Y= 0.0000 Z= 1.0000
