An oil refinery relies on which type of drafter to maintain and update the technical piping drawings used for the construction and maintenance of the facility.

The degree of precision of a given sketch depends on its use.

A sphere has a double-curved exterior that can be formed by revolving a circle around one of its diameters.

An angle is formed by two intersecting lines.

In cavalier oblique projection, the depth is represented at half scale.

It is much easier for a drafter to use a CAD system rather than traditional board drawing because corrections are much easier to make.

An architect does not need to know how many people are going to live in a house before he begins his design.

Frequently a single view supplemented by notes and dimensions can describe a simple object.

All professional engineers are good CAD drafters.

An architect often relies on a ________ to complete the set of technical drawings used in the design of an office building.

This is used in drawings to represent the edge of a solid object:

When designing a home for a client, one of the most important pre-design considerations that an architect needs to address is ________.

A set of written specifications is often included in a set of technical drawings.

A freehand sketch should show attention to proportion, clarity, and correct line widths.

If the faces of a solid are equal regular polygons, it is a regular polyhedron.

Solids are bounded by the surfaces that contain them.

In cabinet oblique projection, receding lines are drawn at full scale.

An electronics drafter is typically involved in the development of wiring schematics for large commercial buildings.

In oblique sketches, the most commonly used angles for receding lines are:

Drafters usually work alone in their cubical without any interaction with other drafters, designers, architects, or engineers.
