You can model a simple block that is mounting to the frame. If you are using shells model a cube and give the face thicknesses a general value like 1 inch. Then adjust the density of the material to make the total weight match that of the components at the cg.

Hi Boggs,

yes, I did that and found center of gravity.
But now I want to do meshing and to apply forces. Skid is made from I beams on the bottom. Since I can not mesh pumps and tanks, I want to apply forces on I beams. How to add forces to I beams and keep same center of gravity.
I am talking about two tanks inside the skid, 2 pumps on 1 tank on top, 1 mixer, few electrical cabinets and it is difficult to keep cg same as it was with simulation of pieces of equipment.
