Rhino 7 or newer.
Keep your design documentation current by using text fields. Rhino 7 features six improved text fields and introduces 11 new text fields. Annotated blocks offer great flexibility and user text can now be stored on layouts. Save time documenting your design by using formulas in the text on your drawings.
Text fields automatically update, ensuring that design changes are always accurately captured. In Rhino 7, annotated blocks allow you to reuse your content on different layouts and across all your projects. Several text fields have been enhanced and several new ones are introduced.
