An annotated sketch is a drawing that displays a fairly good idea of the object being drawn and includes which of the following:
b. all the answers are correct
Orthographic and Isometric Drawings CANNOT be done freehanded, while an Annotated Sketch can be neatly freehanded
True
If an isometric drawing is included as part of an Orthographic drawing, then dimensions and dimensioning of the isometric do not need to be included
True
The light lines that are used to help draw an isometric object or orthographic projection, but are not the actual lines of the object are called
c. construction lines
Select all that apply. The difference between an oblique technical drawing and an isometric technical drawing are
a. an oblique’s horizontal lines can be drawn at 30, 45, or 60 degrees
c. when looking at an oblique drawing you would see one of the sides directly facing you - that side is not distorted in the drawing
d. isometric drawings horizontal lines can only be at 30 degrees
The distance between views in an orthographic drawing should be
d. equidistant - the same distance apart
Which of the following do not need to follow standard guidelines and rules for how to draw it, or put dimensioning rules on it
b. Annotated Sketch

d. dashed lines
For an orthographic drawing, a minimum of 3 views should be included: The sides that should be included in the 3 views are:
d. Top, Side, Front
An orthographic projection is a type of Engineering drawing that
