TCFP Plans Examiner Practice Test

Which of the following is not considered a sectional view of a plan?

1. Longitudinal section

2. Dimensional cross section

3. Transverse section

4. Isometric section

The correct answer is: Dimensional cross section

In the context of architectural and engineering drawings, sectional views are essential for providing a clearer understanding of the internal features of an object or structure. They depict how an object would look if it were cut through horizontally or vertically. The correct response identifies the dimensional cross section as not traditionally considered a sectional view. Sectional views typically include longitudinal, transverse, and isometric sections. Longitudinal and transverse sections involve cutting through the object along specific planes and displaying the resulting view, revealing internal features and dimensions. An isometric section provides a pictorial representation where three-dimensional structures are drawn on a two-dimensional plane to communicate a visual understanding of the layout and proportions. On the other hand, a dimensional cross section usually refers to specifying dimensions on a drawing rather than representing internal features via sectioning. This distinguishes it from the other options that are standard classifications of sectional views utilized in technical drawings to communicate structural details effectively.
