Annotation objects include dimensions, notes, and other types of explanatory symbols or objects commonly used to add information to your drawing.
Annotation objects provide information about a feature, such as the length of a wall, the diameter of a fastener, or a detail callout. Typically, annotation objects are scaled differently than the views of the drawing, and depend on the scale of how they should appear when plotted.
You can control the method that an annotation object is scaled by defining the object either as non-annotative or annotative.
- Non-annotative objects, require a fixed size or scale that is calculated based on the scale used to plot the drawing.
- Annotative objects automatically adjust to display uniformly at the same size or scale regardless of the scale of the view.
