Floor plans are generally the most used of the location drawings. They are sectional plans because they show the view obtained by cutting horizontally through a building at some point above the floor level. It is assumed that you move away from the top part of the building and look down at the plan of the remaining bottom part. This plan view will illustrate the arrangement of the rooms and spaces and their shapes but also show the thickness of all the external and internal walls.

For cutting plane exercises, use the garage simulator or the garage viewer.

Please see this exercise content and answer the next exercise question: which one section plane was used for the garage plan drawing?
