A) Auxiliary views are drawn to show true size and shape.
B) Never draw a break line coinciding with a visible line or a hidden line.
C) Hidden lines are seldom drawn in auxiliary views.
D) The auxiliary view projected from a secondary auxiliary view is called the "trimetric auxiliary view."
E) An auxiliary view projected from the front view shows the depth of the object.

Question 7

Auxiliary views are used for all of the following, except:

A) True size of a plane
B) Edge view of a plane
C) Point view of a line
D) True size of the dihedral line
E) True length of a line

A) Parallel to the inclined surface
B) Parallel to the primary view
C) Perpendicular to the reference plane
D) Perpendicular to the top view
E) Inclined to the finished auxiliary view

Question 9

B) Point view of line
C) Edge view of a plane
D) True size of a plane
E) All of the above

Question 10

Triangulation is a method of dividing a surface into a number of triangles and transferring them to a development.

Question 11

By using 3D CAD, the task of determining intersections and developments is greatly reduced.

Question 12

The gore method is a method of making an approximate development of the double curved surface of a sphere by dividing it into equal sections with meridian planes and substituting cylindrical surfaces for the spherical sections.

Question 13

A surface that may be unfolded or unrolled to coincide with a plane is said to be a developable surface.

Question 14

Reference lines, unlike folding lines, are always parallel to the projection lines between views.

Question 15

When a cylinder is cut by an inclined plane, the resulting shape is elliptical.

Question 16

A break line should be drawn coinciding with a hidden line but never with a visible line.

Question 17

Surfaces that may be unfolded or unrolled to lie flat are said to be a "developable surface."

Question 18

When a cylinder is cut by an inclined plane, the inclined shape is elliptical.

Question 19

When drawing auxiliary views, hidden lines should be included to clarify the data in the drawing.

Question 20

Reverse construction refers to the technique of creating the auxiliary view first and then projecting to the principal views.

Question 21

A "warped surface" defines a sweeping straight line also called a generatrix.
