On plan views, what do exterior solid and parallel dash lines indicate?

• A. Floor bearing on the wall
• B. Column positions
• C. Joist spacing
• D. Beam locations

Answer: (A)

In plan views, exterior walls are shown as solid lines. When you see a second line running parallel to that wall, drawn as a dash line, it marks where the floor loads bear on the wall. This bearing-on-wall indicator tells you where the floor frame transfers its weight into the wall, which is essential for detailing reinforcement and connection points. It’s not used to denote column positions, joist spacing, or beam locations, which use different symbols or notes.
