False or True: Modeling and design visualization are part of the refinement process

True

True or False: The axes of a Cartesian coordinate system are always mutually perpendicular

True

True or False: According to the right-hand rule, if the X-axis is pointing directly at you, positive rotation about the X-axis would be in the clockwise direction

True

True or False: In orthographic projection, visual rays or lines of sight for a given view are perpendicular to each other

False

True or false: For orthographic projection, the engineering custom in the United States dictates the use of first-angle projection

FALSE (US uses the 3rd angle projection)

When making a pipe with a ruled surface, the directrix determines whether the pipe is straight or curved

True

True or False: An intersection Boolean operation can create a null object

True

True or false: In constructive operations, profiles can typically be swept parallel to the work plane

False

A blind sweep indicates that a finite distance is given for the sweep distance
