The engineering design process follows the same steps as the scientific discovery process, or scientific method? True? (Ans- No, there are major differences Descriptive geometry is described in the book and video lecture in relation to: (Ans- Geometry as a means of computation and analysis An engineering drawing can be considered a legally binding document. True? (Ans- YES The term IPS in SolidWorks refers to (Ans- measurement units To create an extrusion i must first draw a sketch on a surface. True? (Ans- Yes but the surface must be flat To create a revolved feature, the profile and the axis of revolution must be coplanar. True? (Ans- Yes To create a solid revolution i must (Ans- Select a plain line from the sketch to use as an axis Make an axis in the sketch using a construction line Use reference geometry to make an axis How do you define datum axes (Ans- -between two points or vertices -along a linear edge -at the intersection of two planar surfaces -at the intersection of a cylinder and a plane through its axis -along the centerline of a cylinder or cylindrical surface defining datum points (Ans- -at a vertex -on a planar surface at specified perpendicular distances from two edges -at the intersection of a line or an axis and a surface that does not contain the line defining datum planes (Ans- -through three noncolinear points -through two intersecting lines -through a line and a noncolinear point -offset from an existing flat surface at a specified distance -through an edge or axis pm flat surface at an angle from that surface -tangent to a surface at a point on that surface -perpendicular to a flat surface and through a line
