In AutoCAD Architecture 2023 toolset, you can dimension object points specified in the AEC dimension style, points on objects picked in the drawing, or user-specified points in the drawing. AEC dimensions associated with objects update when the object changes. User-specified points are not associative and have to be changed manually, if necessary. In addition to AEC dimensions, you can also use AutoCAD dimensions.
An AEC dimension can contain both associative and non-associative points. For example, you can create an AEC dimension that dimensions a wall, a multi-view block representing a floor drain, and user-specified points selected anywhere in the drawing.
