MAE 1351 Exam 1 Questions With
Complete Answers
Profile - Correct Answer a completed sketch that is used to create a solid
Tangent - Correct Answer Touching but not intersecting
Constraints - Correct Answer the geometric relationships, dimensions, or equations,
that control the size, shape, and orientation and include assumptions that the CAD
sketcher makes
Implicitly defined - Correct Answer hidden from the sketcher
Coincident - Correct Answer forces two points to coincide
Concentric - Correct Answer makes the centers of arcs or circles coincide
Collinear - Correct Answer forces a line to be collinear to another line
Linear constraints - Correct Answer define the distance between two points or lines
Radial constraints - Correct Answer specify the radius or diameter of an arc or circle
Angular constraints - Correct Answer measure the angle between two lines
Associative constraints - Correct Answer also called algebraic constraints, is used to
relate one constraint to another via an equational in variables
Variational Technique - Correct Answer solves the algebraic constraint variable all at
once, once there are enough equations
Parametric Technique - Correct Answer solves the algebraic constraints in sequential
order
Driving dimension - Correct Answer changing the dimensions changes the model
Driven dimension - Correct Answer changing the model changes the dimensions
Ground constraint - Correct 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 - Correct Answer Updating the profile to show its new shape after
constraints are changed or added
, Protrusion - Correct Answer when material is added
Cut - Correct Answer when material is removed
Revolved feature - Correct Answer both the profile and axis of revolution must be
coplanar to both lie on sketch plane
Features - Correct Answer protrusions and cuts on the main body of the model
Base feature - Correct Answer the starting overall shape of a model, greatest function
for features
Form feature - Correct Answer a recognizable area of part that has a specific function
or method of manufacture
Fillet - Correct Answer smooth internal edge, reduces stress at a corner and makes
fabrication easier
Chamfer - Correct Answer angled cut rather than smooth transition/radius on
round/fillet
Shelling - Correct Answer removes most of the interior volume of a solid model,
leaving thin wall of material, considered an operation rather than a feature
Ribs - Correct Answer small thin protrusions to support or stiffen a part
Webs - Correct Answer areas of thin material connecting heavier areas of a part
Boss - Correct Answer a slightly raised circular area
Draft - Correct Answer a slight angle to get an object removed from a mold
Groove - Correct Answer a long shallow cut
Island - Correct Answer raised shape
Keyway - Correct Answer a slot extending the length of a hole
Keyseat - Correct Answer a slot on the outside of a shaft
Spot face - Correct Answer a smooth circular inwards cut
Taper - Correct Answer slight angle to help insertion and removal
