Profile - ANSWER-a completed sketch that is used to create a solid Tangent - ANSWER-Touching but not intersecting Constraints - ANSWER-the geometric relationships, dimensions, or equations, that control the size, shape, and orientation and include assumptions that the CAD sketcher makes Implicitly defined - ANSWER-hidden from the sketcher Coincident - ANSWER-forces two points to coincide Concentric - ANSWER-makes the centers of arcs or circles coincide Collinear - ANSWER-forces a line to be collinear to another line Linear constraints - ANSWER-define the distance between two points or lines Radial constraints - ANSWER-specify the radius or diameter of an arc or circle Angular constraints - ANSWER-measure the angle between two lines Associative constraints - ANSWER-also called algebraic constraints, is used to relate one constraint to another via an equational in variables Variational Technique - ANSWER-solves the algebraic constraint variable all at once, once there are enough equations Parametric Technique - ANSWER-solves the algebraic constraints in sequential order Driving dimension - ANSWER-changing the dimensions changes the model Driven dimension - ANSWER-changing the model changes the dimensions Ground constraint - ANSWER-the first constraint applied, they serve as anchors to fix geometry in place, and are usually a line or point having been made coincident with the origin or plane Regeneration - ANSWER-Updating the profile to show its new shape after constraints are changed or added Protrusion - ANSWER-when material is added Cut
