Body from Deformed Shape
You can save the true deformed shape of a part or assembly resulting from running a static or nonlinear study. You can save the deformed geometry as a new configuration or a new document. Use the generated geometry for simulation or manufacturing purposes. This functionality works for solid, shell, and mixed meshes with solids and shells, and is available in SolidWorks Simulation Professional and above
