Key Terms
Te r m Definition
2D constraint Defines how a sketch can change shape or size. Geometric constraints control the
shape and relationships among sketch lines and arcs. Dimensional constraints
control the size of sketch geometry.
degree of freedom In part modeling, determines how a geometric object such as a line, arc, or circle
can change shape or size. For example, a circle has two degrees of freedom,
center and radius. When these values are known, degrees of freedom are said to
be eliminated.
dimensional constraint Parametric dimension that controls the size of a sketch. When changed, the
sketch resizes. May be expressed as a constant value, a variable in an equation, a
variable in a table, or in global parameter files.
geometric constraint Controls the shape and relationships among geometric elements in a sketch.
parametrics A solution method that uses the values of part parameters to determine the
geometric configuration of the part.
