MAE 1351 Exam 1 Study Guide
Profile (Ans- a completed sketch that is used to create a solid
Tangent (Ans- Touching but not intersecting
Constraints (Ans- the geometric relationships, dimensions, or equations, that control the size, shape, and orientation and include assumptions that the CAD sketcher makes
Implicitly defined (Ans- hidden from the sketcher
Coincident (Ans- forces two points to coincide
Concentric (Ans- makes the centers of arcs or circles coincide
Collinear (Ans- forces a line to be collinear to another line
Linear constraints (Ans- define the distance between two points or lines
Radial constraints (Ans- specify the radius or diameter of an arc or circle
Angular constraints (Ans- measure the angle between two lines
- / 2
Associative constraints (Ans- also called algebraic constraints, is used to relate one constraint to another via an equational in variables
Variational Technique (Ans- solves the algebraic constraint variable all at once, once there are enough equations
Parametric Technique (Ans- solves the algebraic constraints in sequential order
Driving dimension (Ans- changing the dimensions changes the model
Driven dimension (Ans- changing the model changes the dimensions
Ground constraint (Ans- 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 (Ans- Updating the profile to show its new shape after constraints are changed or added
Protrusion (Ans- when material is added
Cut (Ans- when material is removed
Revolved feature (Ans- both the profile and axis of revolution must be coplanar to both lie on sketch plane
