Extension Lines

Consists of controls that are used to affect the placement and appearance of extension lines (also called witness lines or projection lines).

Extension Lines category controls

Extension Lines

If on, extension lines are placed. If off, extension lines are not placed.

Key-in: DIMENSION EXTENSION [ON | OFF | TOGGLE]

When you place interior dimensions, it is often useful to suppress extension line placement to avoid an intersecting extension line.

Join When Text Outside

If on, a connecting line between extension lines and text placed outside extension lines is placed.

If off, no connecting line is placed.

Placement of extension lines for the Center Mark mode of the Dimension Radial is controlled in the Tool Settings category.

Offset

The distance, in text height units, between the start of the extension line and the identified element.

A negative value forces the length of the extension line from the dimension line to the end of the extension line. This is relative to the text height. For example, if the text height is 0:6, an offset value of -5 will produce extension lines with a length of 2'-6".

Extension

The distance, in text height units, that the extension line extends beyond the dimension line.

Attributes

Contains controls that can be used to override the Dimension Lines attribute settings and the active settings for color, line style, and line weight for extension lines. For example, this lets you use an extension line as a center line. The controls are analogous to those in the Dimension Lines category.
