Revit Tip: Scale-Independent Annotation Families in Revit

Scalable annotation keeps drawings legible across every view scale. Here’s a reliable workflow to create robust annotation families with text that always reads correctly on sheets.

• Choose the right family category
  • Use Generic Annotation for symbols that aren’t tied to a specific model category (north arrows, keynotes, legends, diagram callouts).
  • Use Tag families (e.g., Multi-Category Tag, Door Tag) when the text should pull parameter values from model elements.
  • Avoid Model Text/Model Lines for notes—they scale with the model and won’t remain a consistent plotted size.
• Build text that always prints consistently
  • Annotation text uses paper units, so it stays the same height regardless of view scale. Define office-standard text types (e.g., 2.0 mm, 2.5 mm, 3.5 mm or 3/32”, 1/8”).
  • In Tag families, duplicate Label Types to match your text standards. Keep naming consistent with your project text types for clarity.
  • Enable Keep Readable on labels where available, so text does not flip upside down.
• Craft a dependable Generic Annotation family
  • Start from the Generic Annotation template. Establish center reference planes and lock geometry to them for reliable alignment.
  • Use subcategories to control line weights, colors, and patterns via Object Styles and View Templates.
  • Add a Masking Region behind text for clarity over hatch-heavy backgrounds. Keep the mask minimal to avoid hiding needed model edges.
  • Favor labels over static text whenever data should be driven by parameters (e.g., Mark, Type Name).
• Make model families display paper-sized text
  • To show consistent-size notes directly on doors, equipment, or fixtures, nest a Generic Annotation into the model family.
  • In the host family, enable Maintain Annotation Orientation (Family Category and Parameters) so the nested annotation stays right-reading.
  • Create Yes/No visibility parameters for Plan, RCP, and Elevation contexts to control where the annotation appears.
  • Expose label values via instance parameters to let users edit text per placed instance without duplicating types.
• Scale-aware graphics, text-stable notes
  • Keep text at fixed paper size; vary only symbol geometry across family types (Small/Medium/Large) to suit coarse vs. fine drawings.
  • Test at 1:50, 1:100, and 1:200 to confirm legibility and spacing. Adjust lineweights and masking as needed.
• Standards, QA, and performance
  • Centralize fonts and text types in your project template. Avoid exotic fonts that can shift on different machines or PDF printers.
  • Keep families lean: minimize nested symbols, avoid high-res images, and purge unused label types.
  • Document usage in your BIM manual and enforce via View Templates and Worksharing reviews.
• Pro tip
  • Unify schedules and tags by using Shared Parameters for label content. This ensures your annotation text aligns with schedules, filters, and data exports.
