Name	Settings Variable	Description
Arrow 1	DIMBLK1	Defines the arrow type for the arrow of the first dimension line (Dim line 1)

Dim baseline spacing	DIMDLI	Sets the spacing of the dimension line for stacked baseline dimensions.
Dim line 1	DIMSD1	Controls the display of the first half of the dimension line, from the first extension line to the origin point of the dimension text.
Dim line 2	DIMSD2	Controls the display of the second half of the dimension line, from the origin of the dimension text to the second extension line.

Ext line fixed	DIMLFXLON	Determines whether fixed length extension lines are used.
Ext line fixed length	DIMFXL	Specifies the length of the extension lines, measured from the dimension line (= DIMEXE excl.), if DIMFXLON is on.
Center mark	DIMCEN	Defines the type of entity that will be created by the Dimcenter tool. The options are: Mark, Line, None
Center mark size	DIMCEN	DIMCEN=0: no center mark, nor center lines are drawn DIMCEN>0: a center mark is drawn, the value of DIMCEN defines the length of the center mark lines. DIMCEN<0: a center mark and center lines are drawn; the abosolute value of DIMCEN defines the extension of the center lines outside the arc or circle and the gap between the center mark and the center lines.
Arc length symbol	DIMARCSYM	Controls how the arc symbol displays in an arc length dimension
Jog angle	DIMJOGANG	Specifies the angle of the oblique dimension line segment in jogged radius dimensions

NOTE	Dimension lines and extension lines are created in the current line type.

Text

Name	Settings Variable	Description
Text style	DIMTXSTY	Defines the text style of the dimension text.
Text color	DIMCLRT	Defines the color of the dimension text.
Text fill	DIMTFILL	Sets the dimension text background. Left: Background = drawing window background color (BKGCOLOR). Right: Color = color defined by DIMTFILLCLR.
Text fill color	DIMTFILLCLR	Defines the text background color
Text height	DIMTXT	Sets the height of the dimension text in drawing units.
Draw frame around text	DIMGAP	Toggles the text frame on/off. A frame is drawn if DIMGAP is negative. In the Drawing Explorer > Dimensions settings dialog, the 'draw frame around text' option is enabled automatically when the value in the Text offset field changes from zero to a non-zero value.
Text offset	DIMGAP	Sets the offset distance around the dimension text and the distance between annotation and hook line created using the Leader command. A negative value for DIMGAP draws a box around the dimension or annotation text. If DIMTVP > 0, only negative values for DIMGAP (= draw text frame) make sense.
Text pos vert	DIMTAD	Defines the vertical text position with respect to the dimension line.
Text pos hort	DIMJUST	Defines the horizontal position of the text with respect to the extension lines.
Text offset vertical	DIMTVP	Sets the vertical position of dimension text above or below the dimension line when DIMTAD=0. The offset equals the product of DIMTVP and the height of the dimension text (DIMTXT).
Text inside align	DIMTIH	Defines whether text that is placed inside the extension lines is aligned with the dimension line or placed horizontally.
Text outside align	DIMTOH	Defines whether text that is placed outside the extension lines is aligned with the dimension line or placed horizontally.

The vertical position of the dimension text is controlled through three settings variables: DIMGAP, DIMTAD and DIMTVP.

The scheme below illustrates the compound effect of these three settings variables:

Settings	Result
DIMGAP=0 DIMTAD=0 DIMTVP=0
DIMGAP=0.2 DIMTAD=0 DIMTVP=0
DIMGAP=-0.1 DIMTAD=0 DIMTVP=0
DIMGAP=0 DIMTAD=1 DIMTVP=0
DIMGAP=0.2 DIMTAD=1 DIMTVP=0
DIMGAP=-0.1 DIMTAD=1 DIMTVP=0
DIMGAP=0 DIMTAD=0 DIMTVP=1
DIMGAP=-0.1 DIMTAD=0 DIMTVP=1

Dimline inside	DIMSOXD	Suppresses the dimension lines to be drawn outside the extension lines.
Text movement	DIMTMOVE	Specifies whether the dimension line moves with the text or that text can be moved independently. This setting also specifies if a leader needs to be drawn if the text is moved away from the dimension line.
Dim scale overall	DIMSCALE	Defines a scale factor for all entities in the dimension block.
