The engineering design process follows the same steps as the scientific discovery process, or scientific method. True? - ANSWER-No; there are major differences The term "IPS" in SolidWorks refers to... - ANSWER-measurement units To create an extrusion, I must first draw a sketch on a surface. True? - ANSWER-Yes, but the surface must be flat What are the fundamental types of sketch constraints? - ANSWER-Geometrical and dimensional To clock a hexagonal feature so that it rests horizontally on one side, I would... - ANSWER-Apply a horizontal constraint To create a revolved feature, the profile and the axis of the revolution must be what? - ANSWER-Coplanar To create a solid of revolution, I must... A) Select a plain line from the sketch to use as an axis B) Make an axis in the sketch using a construction line C) Use reference geometry to make an axis D) Any of the above will work - ANSWER-D) Any of the above will work I have a distance in my sketch preceded by a "sigma" symbol. This means... - ANSWER-It is a dimension driven by a parametric formula Graphical User Interface (GUI) - ANSWER-The format of information on the visual display of a computer, giving its user control of the input, output, and editing of the information primary modeling planes, principal viewing planes, or datum planes - ANSWER-The planes representing the XY-, XZ-, and YZ-planes in a Cartesian coordinate system. sketches - ANSWER-Collection of 2-D entities sketching editor - ANSWER-A software tool used to create and edit sketches. Profile - ANSWER-A planar sketch that is used to create a solid Extrusion - ANSWER-A solid that is bounded by the surfaces swept out in space by a planar profile as it is pulled along a path perpendicular to the plane of the profile Revolved solid - ANSWER-a solid formed when a profile curve is rotated about an axis Constraints - ANSWER-Geometric relationships, dimensions, or equations that control the size, shape, and/or orientation of entities in a sketch or solid model Geometrical Constraints - ANSWER-Definitions used to control the shape of a profile sketch through geometric relationships Dimensional Constraints - ANSWER-Measurements used to control the size or position of entities in a sketch. Algebraic Constraints - ANSWER-Constraint that define the value of a selected variable as the result of an algebraic expression containing other variables from the solid model. Variational techniques - ANSWER-Modeling techniques in which algebraic expressions or equations that express relationships between a number of variables and constants, any one of which can be calculated when all of the others are known. Parametric techniques - ANSWER-Modeling techniques where all driven dimensions in algebraic expressions must be known for the value of the dependent variables to be calculated. Driven Dimension - ANSWER-A variable
