Q.1

The edges of a cube in isometric projection make angles of this many degrees with each other:

  • 30
  • 60
  • 90
  • 120
Q.2

In isometric projection, all distances are approximately this percentage of their true size:

  • 120 percent
  • 80 percent
  • 50 percent
  • 20 percent
Q.3

Angles project true size only when the plane containing the angle and plane of projection are this:

  • Adjacent
  • Aligned
  • Perpendicular
  • Parallel
Q.4

In this type of projection, each of the axes has different ratios of foreshortening:

  • Isometric
  • Dimetric
  • Trimetric
  • Parallel
Q.5

Lines of an isometric drawing that are not parallel to the isometric axes are called this:

  • Trimetric lines
  • Nonisometric lines
  • Multiview lines
  • Dimetric lines
Q.6

This type of axonometric drawing has equal foreshortening along two axis directions and a different amount on the third axis:

  • Dimetric
  • Multiview
  • Isometric
  • Trimetric
Q.7

Isometric drawings have equal foreshortening along each of the three axis directions.

  • True
  • False
Q.8

Nonisometric lines are equally foreshortened.

  • True
  • False
Q.9

If a circle lies in a plane that is not parallel to the plane of projection, it still projects as a circle.

  • True
  • False
Q.10

In isometric drawings, hidden lines are typically omitted.

  • True
  • False
Q.11

Isometric sectioning is typically not used when drawing open or irregularly shaped objects.

  • True
  • False
Q.12

Dimetric drawings have different foreshortening along all three axis directions.

  • True
  • False
Q.13

In isometric drawings, an angle may project to appear larger, but never smaller than the true angle depending on its position.

  • True
  • False
Q.14

If a circle lies in a plane that is not parallel to the plane of projection, the circle projects as an ellipse.

  • True
  • False
Q.15

Isometric drawings, unlike isometric projections, are drawn using the full length measurements of the actual drawing and lack foreshortening.

  • True
  • False
Q.16

Parallel partial ellipses equally spaced at the symbolic thread pitch can be used to represent screw threads.

  • True
  • False
Q.17

An isometric drawing is about 50% smaller than the isometric projection.

  • True
  • False
