Which type of drawing shows the inside construction of a wall or building as if it had been sliced through and the cut face exposed?
A. Section view
A section is drawn as though a cut were made through the object so the hidden construction, such as studs, insulation and footings, can be seen. An elevation shows only the outside surface.
Reference: Construction drawings: section views
A small area of a wall section, such as the connection at the top of a foundation wall, is redrawn at a larger scale to show exactly how it is built. What is this larger drawing called?
B. A detail
A detail enlarges a small part of the work so the pieces and their dimensions can be shown clearly. A schedule is a table (for doors, windows or finishes), and a legend explains the symbols used.
Reference: Construction drawings: detail drawings
A thin line made of alternating long and short dashes runs through the middle of a column and a circular opening on a drawing. What does it mark?
D. The centre line
A centre line is a thin line of alternating long and short dashes that marks the centre of an object such as a column, pipe or round opening. Hidden edges use short dashes of equal length.
Reference: Alphabet of lines: centre line
