It is easiest to sketch on blue line graph paper. True
When drawing an angle line it is easier to tilt the paper. True
The easiest way to draw a straight line is to use the Dot to Dot method? True
The lead type of 7B would be used for manual drafting. False
Guide lines should be used on every sketch to align lettering and should be set to .125. True
When drawing arcs or circles you first mark tangent points at each corner of a square to find the size of a circle. True
The font typically used on a drawing is the single stroke Gothic letter. True
Spacing of lettering is not important on a drawing. False
A "B" size sheet is 22 inches by 34 inches. False
Common scales used are not 1=15.5. True
Sketching any diagram proportionally is most important. True
The best erasers used for mechanical drawings are vinyl erasers. True
When using a computer to create a drawing different font styles can be used throughout the drawing. False
It is important to understand the stroke patterns for creating letters and numbers. True
The first step in drawing an isometric circle is to draw an isometric square. True
An object placed within orthographic view typically has 6 views. True
The United States uses first angle projection for placing views on a drawing. False
Pictorial drawings (oblique and isometric) are used to help interpret and visualize an object. True
When a hole passes through an inclined surface, it appears as elipses in an adjacent view. True
The radial axis where the metal changes from compression to tension is called the "normal" axis. False
When working with an isometric view, measurements can only be made on or parallel to the isometric axis. True
A typical isometric projected line is 60 percent smaller than the true size. False (50 percent)
Fillets are external edges. False
The top view shows the length and height of the object. False
An isometric view can only show two sides of an object. False (3)
Each orthographic view shows two dimensions of an object. True
Views are called planes of projections. True
Alignment pins are used to align the cope and drag together in the casting. True
When modeling the model is first created without the fillets or rounds, then are added later. True
In a sand casting, a gate is used as a pathway for the metal to pass into the pattern void. True
The front view shows the height and width of the object. True
An inclined plane is parallel to the principle views. False
Solid lines used to represent the edges and outlines of geometric features. Visible Object Lines
Thin dashed lines used to represent the edges or outlines of objects that are behind or within an object. Hidden Lines
Thin long-dash-long lines used to locate the center of a geometric feature or to represent the central axis of symmetrical objects. Center Lines
Thick long-dash-dash-long lines used to show the alternate position of an object. Phantom
Thin angled lines used to indicate the solid material that would touch a cutting blade when cutting through an object. Section Lines
Thick hidden line or a thick phantom line terminating with large arrowheads at 90 degrees. Cutting or Viewing Plane Lines
Used to show a portion of the object has been left out. Break Lines
Thin lines terminating in arrowheads with a dimension placed between the straight lines. Dimension Lines
Pair of thin solid lines extending from the dimension lines. Extension Lines
Thin solid lines beginning with a short horizontal line then extending on an angle until it touches the object. Leaders
Secondary auxiliary view is a projection off of the... Primary Auxiliary View
In this type of auxiliary view, a break line is used to indicate the imaginary break in the views. Partial
The lines used to create the auxiliary view should appear as object lines in the finished view. True
This type of auxiliary view is projected onto a plane that is perpendicular to one of the principal planes of projection: Primary
All auxiliary views require section views. False
If the primary auxiliary view is projected from the front view the dimensions for the depth are taken from: Top or Right
In this type of view, the cutting plane line indicates both the location of the cutting plane and the direction of sight. Auxiliary Section
Circular shapes appear in this fashion when viewed at an angle other than 90 degrees. Elliptical
