Acme thread - ANS... -used for rapid and jerky movement
Buttress thread - ANS... -used for rapid omnidirectional movement
Rolled thread - ANS... -also called knuckle thread, rolled from sheet metals
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
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
Features - ANS... -protrusions and cuts on the main body of the model
Base feature - ANS... -the starting overall shape of a model, greatest function for
features
Form feature - ANS... -a recognizable area of part that has a specific function or
method of manufacture
