Variable: Dimensioning_Variables

Dimensioning variables are categorized under seven different tabs in the Dimension Styles Manager when creating and modifying a dimension style.

The following system variables all relate to dimensioning in CADdirect.

DIMADEC Determines the number of decimal places used for displaying angular dimension text.
DIMALT Controls the ability to use alternate unit systems in dimensions in addition to the default units.
DIMALTD Sets the number of decimal places used in alternate units.
DIMALTF Specifies the scale factor for alternate units.
DIMALTRND Determines rounding of alternate dimension units.
DIMALTTD Controls the number of decimal places for alternate unit tolerances.
DIMALTTZ Turns on and off the suppression of zeros in limits or tolerances included as part of alternate dimensions.
DIMALTU Specifies the text format for alternate units.
DIMALTZ Turns on and off the suppression of zeros for alternate unit dimensions.
DIMAPOST Specifies the prefix and/or suffix that appears in alternate unit dimension text.
DIMASO Toggles on or off the creation of associative dimensions.
DIMASZ Sets the size of the dimension arrowheads.
DIMAUNIT Controls the unit format for angular dimensions.
DIMAZIN Controls the display of leading and trailing zeros for angular dimensions in decimal format.
DIMBLK Substitutes a user-specified block instead of the arrowheads for both ends of a dimension line.
DIMBLK1 Substitutes a user-specified block instead of the arrowhead for the first end of the dimension line.
DIMBLK2 Substitutes a user-specified block instead of the arrowhead for the second end of the dimension line.
DIMCEN Controls the display of non-associative center marks and center lines for circles and arcs. A value of 0 turns off center marks and lines.
DIMCLRD Allows you to change the color of the dimension lines, leader, and arrowheads.
DIMCLRE Sets colors for dimension extension lines.
DIMCLRT Sets colors for dimension text.
DIMDEC Sets the number of decimals displayed for tolerances in dimensions.
DIMDLE Controls the distance beyond the extension line that the dimension line extends when using dimension lines with oblique strokes.
DIMDLI Controls the spacing offset of the dimension lines when drawing baseline dimensions.
DIMDSEP Determines the character that is used as a decimal separator when creating dimensions in decimal format.
DIMEXE Determines how far extension lines stretch beyond dimension lines.
DIMEXO Controls the amount of space between the entity being dimensioned and the extension line.
DIMFIT Places arrowheads and text inside or outside extension lines based on the space available between extension lines.
DIMGAP Controls the amount of space before and after the dimension text and the closest end of the dimension line.
DIMJUST Sets the horizontal position of the dimension text to one of the following options: centered (0, the default value); next to the first extension line (1); next to the second extension line (2); perpendicular to the first extension line (3); perpendicular to the second extension line (4).
DIMLFAC Specifies the scale factor for linear dimensions.
DIMLIM Generates dimensions as upper and lower tolerance limits.
DIMLUNIT Sets units for all dimension types, except Angular, to one of the following: Scientific (1), Decimal (2), Engineering (3), Architectural (4), Fractional (5), or Windows Desktop (6).
DIMLWD Sets the lineweight for dimension lines.
DIMLWE Sets the lineweight for extension lines.
DIMPOST Specifies the prefix and/or suffix that appears in dimension text.
DIMRND Allows you to round off dimension measurements to the specified value.
DIMSAH Toggles on or off the use of custom-defined blocks for dimension arrowheads.
DIMSCALE Controls the scale factor for variables affecting dimensioning size, distance, and offset.
DIMSD1 Toggles on or off the display of the first dimension line.
DIMSD2 Toggles on or off the display of the second dimension line.
DIMSE1 Toggles on or off the display of the first extension line.
DIMSE2 Toggles on or off the display of the second extension line.
DIMSHO Controls the update of dimension measurements while increasing or decreasing the size of a dimensioned entity.
DIMSOXD Toggles on or off the placement of dimension lines outside the extension lines.
DIMSTYLE Allows you to list the available dimension styles and apply a new style from those available.
DIMTAD Determines the vertical placement of dimension text in relation to the dimension line. The default value (0) centers the dimension text between the dimension lines. The other values allow you to place the dimension text above or below the dimension line.
DIMTDEC Allows you to specify the number of decimal places to display tolerance values in a dimension.
DIMTFAC Not implemented.
DIMTIH Positions dimension text inside the extension lines either horizontally (on) or aligned with the dimension line (off).
DIMTIX Positions dimension text between extension lines.
DIMTM Specifies the minimum tolerance or lower limit value for dimension text.
DIMTOFL Toggles on or off the drawing of a dimension line between the extension lines when the text is placed outside the measured points.
DIMTOH Sets the placement of dimension text outside the extension lines. The default value (1) draws text horizontally. Changing the value to off (0) aligns text with the dimension line.
DIMTOL Appends plus and minus tolerance values to dimension text.
DIMTOLJ Not implemented.
DIMTP Specifies the maximum tolerance or upper limit value for dimension text.
DIMTSZ Determines the size of the oblique strokes drawn, replacing the arrowheads in linear, radius, and diameter dimensioning.
DIMTVP Sets the vertical position of dimension text relative to the dimension line.
DIMTXSTY Specifies a new value for the dimension text style.
DIMTXT Specifies the height of dimension text. If the current text has a fixed height, DIMTXT will not override this setting.
DIMTZIN Determines the suppression of leading zeros in measurements and decimal dimensions when applying tolerance values.
DIMUNIT Allows you to set the format for dimension units to the following: Scientific (1), Decimal (2), Engineering (3), Architectural - stacked (4), Fractional -- stacked (5), Architectural (6), Fractional (7), Windows Desktop (8).
DIMUPT Allows you the option of controlling only the dimension line location, or both the dimension line location and the text position.
DIMZIN Determines the suppression of leading and trailing zeros in primary dimension text.
