• Orthographic, Section, Isometric, & Auxiliary

• Top, Front, Back, & Rear

What are the 3 standard Orthographic Views?

• Top, Front, & Right Side

• Top, Rear, Left Side, and Bottom

CAD is an acronym that stands for...

An Object Line on an engineering drawing represents...

• a hidden surface.

• a phantom surface.

• a visible surface.

• a deleted surface.

Why are Section Views used on engineering drawings?

• They represent an inverted view of the part.

• They are used to apply dimensions to.

• They combine 2 orthographic views in to one view.

• They explain a part in better detail that may be difficult to visualize in an orthographic view.

An engineering drawing that is created at a 2:1 scale is _______ the size it is in actuality.

• twice

• half

• triple

• a quarter

Dashed lines on an engineering drawing represent...

An engineering drawing that has been signed and approved by all authorized personnel is a legal document in a court of law?

• True

• False

• Sometimes

• It depends

Auxiliary Views are used for...

• showing multiple angled surfaces.

• showing a Top View without needing to show the Top View.

• simplifying the Section View.

• giving a more accurate view perpendicular to the surface to show detail that may be confusing on the orthographic views.

Dimensions on engineering drawings are precise measurements of what is expected on the finished product or part you are creating on CAD.

• True

• False

• Unless the person building it changes the dimension

• They are rough estimates.
