When a part or subassembly is placed with constraints using the Assemble option, it must be fully constrained to be considered a parametric model. If it is not fully constrained, it is considered a packaged component and it is nonparametric. Assembly Modeling in Wildfire

Unformatted text preview: Assembly Modeling in Wildfire Mechanism Design Traditional assembly constraints require the parts to be fully constrained, this means they are fixed and have zero degrees of freedom (DOF). To turn an assembly into a mechanism in which the parts are free to move, connections (joints) are used rather than constraints. Assembly Modeling in Wildfire Assembly Modeling in Wildfire Mechanism Connections (joints) Pin (1 rotational DOF) Cylinder (1 rotational, 1 linear DOF) Slider (1 linear DOF) Ball (3 rotational DOF) Bearing (1 linear, 3 rotational DOF) Rigid (Fixed) (0 DOF) Planar (2 linear, 1 rotational DOF) Assembly Modeling in Wildfire Assembly Modeling in Wildfire DEMO Assembly Modeling in Wildfire Assembly Modeling in Wildfire...
