3DCS Mechanical Modeler for V6 is specially geared for the mechanical world. 3DCS Mechanical Modeler is an easy to use add-on that allows users to model mechanical and kinematic assemblies with full range of motion. These assemblies use new joint and constraint assembly definitions instead of the 3-2-1 move routines which allow automatic extraction of the assembly process, making the modeling process faster and easier. This, in addition to a new kinematic solver that allows tolerance analysis of over-constrained assemblies, makes 3DCS Mechanical an excellent fit for performing variation analysis on engines, switches, gears and other mechanical components.
