CDT Drafting & Design Principles & Techniques 3

Question 1

What is the purpose of an auxiliary view in technical drawing?

Accepted Answer

To show the true shape of an inclined surface not visible in standard views

Answer

An auxiliary view is projected onto a plane parallel to the inclined surface, revealing its true size and shape.

Question 2

In multiview drawing, which view is typically positioned directly below the front view?

Accepted Answer

Bottom view

Answer

In third-angle projection (US standard), the bottom view is placed below the front view, showing what is seen looking up at the object.

Question 3

What is the function of 'crosshatching' in a section view?

Accepted Answer

To indicate the material cut by the cutting plane

Answer

Section lines (crosshatching) are drawn at 45° on cut surfaces to distinguish solid material from voids and indicate that the surface was cut.

Question 4

Which geometric relationship is true of two lines that are 'parallel' in space?

Accepted Answer

They never intersect and remain equidistant

Answer

Parallel lines maintain a constant distance from each other and never intersect, regardless of how far they are extended.

Question 5

When dimensioning a drawing, the 'unidirectional' system means:

Accepted Answer

All dimension numerals are read from the bottom of the sheet

Answer

In the unidirectional system, all dimension values are oriented to be read from the bottom of the drawing sheet, regardless of dimension line direction.
