It is often described as the unambiguous communication of a design or design intent.

What is the goal of a technical drawing.

100

Arrows in a dimension point to these lines.

What are extension lines?

100

This symbol is used to indicate diameter. (You must draw the symbol on the board or paper.)

What is Ø?

100

This is the text height used in an AutoCAD decimal inch drawing.

What is 0.125"?

100

This is the command used in AutoCAD to fill in a solid portion of a sectioned object with section lines or other section patterns.

What is the HATCH command?

100

In general, section views are used to show these.

What are interior details?

200

Adds information such as size, location, and/or characteristics of features to a drawing.

What is dimensioning?

200

This is the number of whole millimeters that 1/8" typically equals.

What is 3 millimeters?

200

This is a larger circular opening added on top of a lower, smaller hole or shaft, typically indicated by this symbol:  .

What is a counterbore (or spotface).

200

This is the command that can be used to shorten a line to a boundary entity.

What is trim?

200

This AutoCAD command has many uses, one of which is to create the arrowhead at the end of a cutting-plane line to show where a section-view is located.

What is MULTILEADER.

200

A section view such as the one shown below which has a cutting-plane line that turns/bends to reveal multiple features in different planes of the object.

What is an offset section?

300

This is the distance that the first dimension is typically placed away from the object when working in inches.

What is 3/8"?

300

This is the term often used to describe the number of decimal places that are to be shown when dimensioning an object. 

What is precision?

What is gdt?

300

This command will create a specified number of duplicates of the selected geometry along either a centerpoint, in rows and columns, or along a path.

What is ARRAY.

300

These lines are NOT typically drawn when a view of an object is converted to a section view. 

What are hidden lines.

300
