Deck 11: Size and Location Dimensions

Question 1

The term ____ refers to a thin, inclined straight line terminating in an arrowhead.

A) extension
B) leader
C) feature
D) dimension

Answer 1

B

Question 2

Describe the elements and information on a drawing.

Answer 2

Drawings consist of several types of lines that are used singly or in combination with each other to describe the shape and internal construction of an object or mechanism. However, to construct or machine a part, the blueprint or drawing must include dimensions that indicate exact sizes and locations of surfaces, indentations, holes, and other details. The lines and dimensions, in turn, are supplemented by notes that give additional information. This information includes the kind of material used, the degree of machining accuracy required, details regarding the assembly of parts, and any other data that the craftsperson needs to know to make and assemble the part.

Question 3

Explain why it is important to dimension drawing completely.

Answer 3

All drawings should be dimensioned completely so that a minimum of computation is necessary and the parts can be built without scaling the drawing.

Question 4

What are location dimensions made from and why?

Question 5

List the three size dimensions that are common to every solid.
