About this asset

This Addendum Symbol is a Revit family annotation component designed for marking revisions on architectural construction documents. The Addendum Symbol is a clean, minimalist drafting component featuring a simple equilateral triangle geometry. It is designed to be highly legible at standard drawing scales, ensuring that revision markers remain clear when plotted on construction sets. The geometry is fixed to provide consistent graphical representation across all sheets in a project. As a native Revit annotation family, it maintains scale-independent line weights, allowing the symbol to display correctly regardless of the viewport scale applied to the sheet. This component is essential for maintaining professional standards in technical documentation.

The download is a 51 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.

To use this component, load the family into your Revit project and access it through the Annotate tab. It is typically placed directly onto sheets or within drafting views to highlight areas of change. Because it is a generic annotation family, it does not host to model elements, offering flexibility for manual placement. Users can easily duplicate the family to create custom variants if specific project standards require different line weights or additional labels for revision tracking.

This symbol is primarily utilized during the construction documentation phase of architectural, structural, and MEP projects. It is essential for clearly communicating changes, addendums, and site instructions to contractors and consultants. Professionals working on complex tender sets or large-scale building projects will find this an indispensable tool for maintaining clear revision history. It pairs seamlessly with standard title blocks and revision schedules, ensuring that every modification is properly flagged and tracked according to industry-standard BIM workflows and project management protocols.
