@ boekenwuurm: Hrm, if ya'll are talking about accurate simulations of material stresses and behavior, the more accurate the simulation the longer it'll take. Solidworks uses COSMOS to generate FEA (finite element analysis) to show the effects of stress on a structure. Some variables are like.. the thickness of the materials, the type of materials, where the focus of the force being placed on the structure is located, etc. Of course Solidworks also takes into consideration the welding too. There's a lot that goes in to make something accurate.

To render one FEA, the thing takes hours. The more complex the structure the more hours, even days.

Of course we're all used to waiting for hours with Bryce.....    :-)
