Cross-section plans, or sections as they are more commonly known, are orthographic projections of structures with a cut transecting them. A three-dimensional drawing is shown in a two-dimensional view in this type of projection. The cut is typically vertical and reveals details that a horizontal cut in a plan section drawing would not. A cross section's two-dimensional quality allows for more information to be included than a three-dimensional concept. In general, a cross-section plan will necessitate multiple cross-sections, which will increase depending on the project's complexity. By selecting section planes on a 3D model, you can create any cross-section with BIM.
