Lee, maybe I was not clear, this is a steel material form, I now need to calculate the single rules of harmony which calculated weight.
such as: -A*B(That plate) ,-(Prefix) ,A*B*7850E-6(Weight per meter) ,2*(A+B)*1e-3(Surface area per meter)
For example, the first line of animation, -50x1470x10788x7.85/1000^2=6224.4kg ,6224.4x2=12448.8kg
How can we make this calculation?
