Annotation tools let you easily insert multiline text annotations with or without leaders, keynotes that scale and layer key automatically, and cut lines with single or double breaks that can mask or trim underlying objects. You can edit multiline attributes used in multi-view blocks. You can create and manipulate many kinds of multiline leaders. Annotation scaling allows you to plot annotation at the same height or size at different specified annotation scales. You can link display configurations to specific annotation scales as well, and carry participating annotation scales from one AEC object to another. The keynote tools support both reference keynoting and sheet keynoting. You can manually select keynotes to insert, or you can apply pre-specified keynotes at various levels: object, object component, two-dimensional (2D) section/elevation linework, or detail component.
