About this asset

This Revit annotation symbol provides a standardised graphical marker for 2x12 floor joists at 16-inch on-centre spacing. Designed for structural documentation, this annotation symbol features a clean, professional line-based representation for floor joist layout plans. It includes two directional arrows at the terminal ends of a horizontal line, clearly indicating the span direction. Centred above the line is the text label '2x12 FLOOR JOIST' with '@ 16" O.C.' positioned directly below. The geometry is strictly 2D, ensuring that it remains readable regardless of the project scale or view orientation, maintaining consistency across all structural sheets and framing plans within the BIM environment.

The download is a 82 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Load this family into your project and utilise it within drafting views or floor plans to annotate structural framing. As a standard annotation object, it remains view-specific and scales automatically with the project view settings. Users can place the symbol along the joist path, adjusting the length to suit specific span requirements. It is best managed through standard Revit annotation categories, allowing for visibility control via visibility graphics settings to ensure clean, clutter-free construction documentation.

This symbol is essential for residential and light-commercial structural framing plans, particularly when detailing timber floor systems. It pairs effectively with structural framing families and standard floor plan views, providing clear, concise information for contractors and engineers on-site. Professionals typically search for this asset when creating construction documents, framing schedules, or structural notes for wood-frame projects. It serves as a reliable tool for communicating joist specifications and spacing requirements, ensuring accurate execution during the construction phase of a project.
