true

there are six preset isometric viewpoints

true

there are four preset orthographic viewpoints

true

there are eight solid primitives in cad

true

the view cube can be used to change the display between a perspective and parallel projection

true

the PLAN command can be used to restore a view parallel to any saved UCS

true

model space viewports must be rectangular but can overlap

true

the VPORTS command opens the viewports dialog box in which the current viewport configuration can be saved (named)

true

a solid extrusion has mass properties buct a surface estrusion does not

true

an extrusion, either surface or solid, can be constructed below or above the current XY plane

True

false

the fundamental difference between a sweep and a loft is the use of guide curves in a sweep

false

a helix cannot be used as a shape for a sweep, but can be used as a path for a sweep

true

after the SLICE command is used, the history of the solid must be reset in order to retain it

false

true

a countersink is similar to a counter bore with straight edges

false

a boss is raised above the surface of an object and can serve as a seating surface for a fastener

true

architectural modeling can be created by first drawing the profile of the modeling as a closed 2D shape, then extruding the profile

true

the jitter and line extensions of properties of a visual style can be used to create a hand-sketched display of the objects in the scene

true

custom materials are only available in the drawing in which they were created, unless saved to a library

true

a background in a scene can be a solid color, gradient of colors, bitmap file, the sun and sky, or the current drawing background color
