Dimension

Dimensions are a form of drawing annotation consisting of both text and geometric elements; they can be linear, radial (two types) or angular. Linear and radial dimensions display the distances between particular points in the 3D model whilst angular dimensions display the angles between directions.

A simplified view of that part of the Database hierarchy (see Draw Database Basic Hierarchy for further information) that relates to dimensioning is:

DRAW allows dimensions to be created quickly and easily (using the cursor), with many attributes of the dimension elements being set automatically by cascading values from the owning LAYE element.
