|Style|| Displays the active dimension style, which is set on the Dimension Styles dialog. The option menu lets you select other available dimension styles.
If you change a tool setting from the default, the setting is highlighted in blue, and an asterisk appears next to the Style name.
|Alignment||Determines the axis along which the dimension is aligned.|
|Location|| Controls the location of dimension text:
|Dim Offset||Sets a standard offset for the placement of a dimension.|
|Select Multiple Elements|
|Annotation Scale Lock icon|| Sets the Annotation Scale
Lock. When this lock is on, the annotation scale is applied to linear dimension that is placed.
By default, the annotation scale is taken from the model's Annotation Scale setting. You can change it only in the model's properties in the Properties dialog. The exception is when the model's Propagate Annotation Scale property is off. In that case, the annotation scale can be controlled independently for each element via its properties.
|Start Extension|| If on, sets the optional terminator for the beginning of dimension lines.
|End Extension|| If on, sets the optional terminator for the end of dimension lines.
|First Terminator|| If on, sets the optional terminator for the beginning of the first dimension line.
|Joint Terminator|| If on and the mode is Linear Size or Linear Single, sets the optional terminator at the intersection of the left and right terminators (at internal extension lines), or at the intersection of an extension line and a dimension line (to replace two arrows pointing toward each other).
|Text Alignment|| If the mode is Dimension Element, Dimension Linear, or Dimension Size Perpendicular to Points, sets the orientation of dimension text:
|Text Frame|| If on, controls the framing of dimension text:
|Prefix Text|| If on, sets the optional symbol for placement before dimension text.
|Suffix Text|| If on, set the optional symbol for placement after dimension text.
