Quiz Questions

01. Working drawings are a set of assembly and detail drawings.

02. Parallel partial ellipses equally spaced at the symbolic thread pitch can be used to represent screw threads.

03. Using CAD, you are typically able to select viewing distance, focal point, z-axis convergence, and arc resolution scale for perspective representations.

04. A double-curved surface is generated by a curved line and has straight-line elements.

05. A normal surface is perpendicular to a plane of projection.

06. An extension line is a thin, dark, solid line that extends from a point on the drawing to which a dimension refers.

07. In assembly sections, bolts, nuts, and keys are typically left un-sectioned.

08. Non-isometric lines are equally foreshortened.

09. The horizon in the perspective view should be drawn at the same level above the ground line as the height of the station point.

10. A ruled surface is one that may be generated by sweeping a generatrix along a path.

11. A total of three principal views are arranged in a standard way.

12. A metric dimension that is a whole number does not show a decimal point or a zero.

13. Hidden lines are usually included on assembly drawings.

14. Isometric drawings, unlike isometric projections, are drawn using the full length measurements of the actual drawing and lack foreshortening.

15. The picture plane should never be placed behind the station point.

16. An auxiliary view is an orthographic view that is not a standard projection.

17. Before other communication methods developed, people informed themselves through visual means, including pictures.

18. It is permissible to letter a dimension value over any line on the drawing.

19. In 3D assemblies, the last part added to the assembly becomes the parent part.

20. In isometric drawings, hidden lines are typically omitted.
