SOLUTION

Explanation:

Some important points about Isometric Drawing:

  • It is a type of pictorial projection in which all three dimensions of an object are shown in one view and if required, the actual sizes can be measured directly from it
  • The perpendicular edges of an object are drawn on 3 axes at 120° to each other.
  • All lines parallel to the isometric axes in an isometric drawing are called isometric lines
  • Non-isometric lines are not parallel to any of the isometric axes
  • Measurement can be made only on the isometric lines and axes

There are three types of axonometric projections:

Trimetric projection: All three axes of space appear unequally foreshortened. None of the angles is equal.

Dimetric projection: Two of the three axes of space appear equally shortened. Two angles are equal.

Isometric projection: All three axes of space appear equally foreshortened. All three angles are equal.
