Linear Dimension (LDIM) elements (refer to Linear Dimensions for further information) exist for each linear dimension that appears on a drawing. LDIM elements own Dimension Point elements, which specify the points between which dimensions are drawn. Two other types of linear dimension are:

Radial Dimension (RDIM) elements (refer to Radial Dimensions for further information) exist for each radial dimension that appears on a drawing, being defined by a database element and an attribute (e.g. DIAM of a CYLI).

Pitch Circle Dimension (PDIM) elements (refer to Pitch Circle Dimensions for further information) exist for each pitch circle dimension that appears on a drawing. PDIM elements own Dimension Point elements, which specify the points between which dimensions are drawn. The graphics for a PDIM are similar to those for an RDIM.

Angular Dimension (ADIM) elements (refer to Angular Dimensions for further information) exist for each angular dimension that appears on a drawing. ADIM elements own Dimension Direction elements, which specify the end points of the dimension arc and its origin.
