DIMASO DDIM
Type: Switch
Saved in: Drawing
Initial value: On
Controls the associativity of dimension objects.

On Creates an association between the elements of the dimension. The elements are formed into a single object. If the definition point on the object moves, the dimension value is updated.
DIMASO is not stored in a dimension style.
DIMASSOC DDIM
Type: Integer
Saved in: Drawing
Initial value: 2
Controls the associativity of dimension objects.
0 Creates exploded dimensions. There is no association between the various elements of the dimension. The lines, arcs, arrowheads, and text of a dimension are drawn as separate objects.
1 Creates non-associative dimension objects. The elements of the dimension are formed into a single object. If the definition point on the object moves, the dimension value is updated.
2 Creates associative dimension objects. The elements of the dimension are formed into a single object, and one or more definition points of the dimension are coupled with association points on geometric objects. If the association point on the geometric object moves, the dimension location, orientation, and value is updated.
DIMASSOC is not stored in a dimension style.
Drawings saved in a format previous to AutoCAD 2002 retain the setting of the DIMASSOC system variable. When the drawing is reopened in AutoCAD 2002 or later, the dimension associativity setting is restored. If a legacy drawing is opened in AutoCAD 2002, the DIMASSOC system variable takes on the value of the legacy drawing's DIMASO system variable.
DIMASZ DDIM
Type: Real
Saved in: Drawing
Initial value: 0.1800
Controls the size of dimension line and leader line arrowheads. Also controls the size of hook lines.
Multiples of the arrowhead size determine whether dimension lines and text should fit between the extension lines. DIMASZ is also used to scale arrowhead blocks if set by DIMBLK. DIMASZ has no effect when DIMTSZ is other than zero.
DIMATFIT DDIM

Initial value: 0
Assigns colors to dimension lines, arrowheads, and dimension leader lines. Also controls the color of leader lines created with the LEADER command. The color can be any valid color number. Integer equivalents for the BYBLOCK and BYLAYER properties are 0 and 256, respectively.
DIMCLRE DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Assigns colors to dimension extension lines. The color can be any valid color number. See DIMCLRD.
DIMCLRT DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Assigns colors to dimension text. The color can be any valid color number. See DIMCLRD.
DIMDEC DDIM
Type: Integer
Saved in: Drawing
Initial value: 4
Sets the number of decimal places displayed for the primary units of a dimension. The precision is based on the units or angle format you have selected.
DIMDLE DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0000
Sets the distance the dimension line extends beyond the extension line when oblique strokes are drawn instead of arrowheads.
DIMDLI DDIM
Type: Real
Saved in: Drawing
Initial value: 0.3800
Controls the spacing of the dimension lines in baseline dimensions. Each dimension line is offset from the previous one by this amount, if necessary, to avoid drawing over it. Changes made with DIMDLI are not applied to existing dimensions.
DIMDSEP DDIM
Type: Single character
Saved in: Drawing
Initial value: Decimal point (“.”)
Specifies a single-character decimal separator to use when creating dimensions whose unit format is decimal.
When prompted, enter a single character at the command line. If dimension units is set to Decimal, the DIMDSEP character is used instead of the default decimal point. If DIMDSEP is set to NULL (default value, reset by entering a period), AutoCAD uses the decimal point as the dimension separator.
DIMEXE DDIM
Type: Real
Saved in: Drawing
Initial value: 0.1800
Specifies how far to extend the extension line beyond the dimension line.
DIMEXO DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0625
Specifies how far extension lines are offset from origin points. If you point directly at the corners of an object to be dimensioned, the extension lines do not touch the object.
DIMFIT DDIM
Type: Integer
Saved in: Drawing
Initial value: 3
Obsolete. Has no effect in AutoCAD 2000 except to preserve the integrity of pre-AutoCAD 2000 scripts and AutoLISP routines. In AutoCAD 2000, DIMFIT is replaced by DIMATFIT and DIMTMOVE. Displays at the command prompt.
0 Both text and arrowheads are placed on the outside extension lines
1 Text is placed between the extension lines and arrowheads are placed on the outside
2 Arrowheads are placed between the extension lines and text is on the outside
3 Text is placed between the extension lines and places the arrowheads on the outside
4 Same as 3 except leaders also connect the text to the dimension line unlike no. 3
5 Both arrowheads and text are placed on the inside of the extension lines, unless not enough space is between the extension lines
DIMFRAC DDIM
Type: Integer
Saved in: Drawing
Initial value: 0
Sets the fraction format when DIMLUNIT is set to 4 (Architectural) or 5 (Fractional).
0 Horizontal
1 Diagonal
2 Not stacked (for example, 1/2)
DIMGAP DDIM
Type: Real
Saved in: Drawing
Initial value: 0.0900
Sets the distance around the dimension text when the dimension line breaks to accommodate dimension
