Simulate and analyze design concepts.
Use ForceEffect to create Free Body diagrams to simulate design options during the concept phase of a design. ForceEffect simulations create the engineering calculations for you to determine the viability of each design concept. When you are finished, you can save the vector geometry and then open it as either a part or assembly skeleton sketch.
The Help panel in ForceEffect contains links to the help files, sample files, and Getting Started guide.
Another great resource is the free ForceEffect iBook available here.
