Answer:
C. Primary auxiliary view
Explanation:
A secondary auxiliary view is obtained by projecting the primary auxiliary view to the plane which lies perpendicular to the true (complete) edge length of the primary auxiliary view. In the secondary auxiliary view, the sides that come after the closer edges of the primary auxiliary view becomes visible making it appear that the side after the closer edge is the visible top of the view
Therefore, the drawing necessary for him to create the secondary auxiliary view is the primary auxiliary view.

Just so y'all know! make them brainliest!!
Joseph is an engineer at a construction firm. He has been given the task of developing engineering drawings for a few metal pieces used by the firm. These metal pieces have a slanted surface area. Joseph has developed orthographic projections. What should the lines he used to create the auxiliary view appear as in the finished view?
A.
object lines
B.
construction lines
C.
reference lines
D.
projection lines
Answer:
D.
Explanation:
Projection lines are those extended lines used to project the surface of 2D object.
In orthographic projections, it is difficult to draw slanted or inclined surface without getting distorted. So, engineers use auxiliary view to show the exact portrayal of the slanted surface.
The lines drawn to point the projection in auxiliary view is called the projection lines.
Therefore, option D is correct.
