Certain entities also double as objects used for annotation purposes, defined in paper space. The following objects have annotational support:
- Text
- MText
- Dimenions
- Leaders
- Balloons
- Tolerance
- Tables
- Blocks
- Attributes
- Hatches
These objects have the unique property of an annotation scale; custom objects may also use this value. Annotation scaling maintains visual fidelity across multiple sheets. Based on the annotation scale of a viewport, a single object might draw itself differently in various viewports. This value is used to ensure that an annotative object appears the same in mutliple viewports, despite a viewport’s own scale.
