factor: default is 25.4 which is correct
for SI millimeter metric units as alternate units (inches converted to millimeters) |

center mark passes through circle
diameter and projects beyond circle by the distance equal to this value |

BYBLOCK
|
DIMCLRE
|
Dimension extension line color --
default is BYBLOCK
|
DIMCLRT
|
Dimension text color -- default is
BYBLOCK
|
DIMDLE
|
Dimension line extension --
default is 0.0 which is OK for arrows, but should
be set to 0.09 if using ticks |
DIMDLI
|
Dimension line increment: this is
the distance which each dimension
line is automatically spaced from the last one when using the "continue" or "baseline" sub-commands, or when dimension text will not fit within the space between extension lines (the next dimension in a string will get offset from that one by the value of this variable) -- default is 0.38, but should be set to 0, unless you intend to use the "baseline" sub-command (which is rare in architectural drawings) |
DIMEXE
|
Dimension extension line extension
beyone the dimension line --
default is 0.18, but should be set to 0.09 |
DIMEXO
|
Dimension extension line offset:
this is the distance from the origin

DIMGAP
|
Dimension space between dimension
line and text when dimension
line is broken to accommodate the dimension text -- default is 0.09 which is OK, since this is never used in architectural drawings -- dimension lines should never be broken for dimension text in architectural drawings |
DIMLFAC
|
Dimension scale factor -- default
is 1
This would only change if you were
inserting a drawing which is
dimensioned at a different scale than 1:1 -- You would set this to the reciprocal of the scale conversion factor as described in the chapter on "Scale" in this text. For instance, say you want to insert a detail to be scaled at 1"=1'-0" into a drawing which will be plotted in model space at 1/4" = 1'-0". The detail drawing would be inserted at a conversion scale factor of 4, so that it appears 4 times the size of the main drawing to be plotted at 1/4"=1'-0". The detail would then be dimensioned, first setting DIMLFAC to 1/4 (that is the reciprocal of the conversion factor. Note that none of this complicated process is necessary if you always plot your drawings in paper space at 1=1 scale, zooming the various viewports to their respective scales. |
DIMLIM
|
Controls the way tolerances are
displayed when using tolerances for
a dimension
0=off (default) tolerances are
displayed as plus-minus number
1=on tolerances are displayed in
high value and low value one above
the other
Tolerances and therefore this
variable is rarely used for architectural
drawings |
DIMPOST
|
Dimension text prefix, suffix, or
both -- default is none
If you wanted to have the words
"Above Finished Floor" appended
to the dimension, while still allowing the dimension as measured by the program to be used and remain associative, you could set the value of this variable to
<>Above Finished Floor
The two angle brackets together
represent the placement of the
associative dimension |
DIMRND
|
Dimension rounding value --
default is 0.0, should be set to 0.625,
which is 1/16" for architectural drawings |
DIMSAH
|

blocks for each end of the dimension
line
0=off (default) -- when set to
off, you are not allowed to use two
different blocks for the dimensioning arrows
1=on -- when set to on, you may
use two different blocks for each
end of the dimension line, stored as DIMBLK1 and DIMBLK2 |
DIMSCALE
|
Dimension overall feature scale
factor -- default is 1.0 but if you
want to plot your drawing in model space, you should set this variable to the plot scale factor (e.g. 1/4"=1'-0" plot scale, the plot scale factor is 48), but if you intend to plot in paper space only, set this variable to 0. It is recommended that you always plot in paper space, and that this variable should be set to 0. |

Suppresses outside dimension lines
-- default is 0, should be set to 1
0=off -- (default) if dimension
arrows do not fit between extension lines,
the dimension line and arrows will be drawn to the outside of each extension line, -- this is not normally desirable in architectural drawings
1=on -- forces arrows to be drawn
toward the inside of extension
lines, regardless of whether they will fit, this is a better appearance for most architectural drawings |
DIMSTYLE
|
Dimension style -- default is
*UNNAMED (Read Only) -- you can
create as many styles as you want by setting variables as you wish, and using the DIM<RET> SAVE<RET>[name] command sequence, with [name] being the name you assign to the dimension style. To use a style that has already been saved, you need to restore it by using the DIM<RET>RESTORE<RET>[name] command sequence |
DIMTAD
|

line -- default is 0, should be set
to 1
0=off -- dimension text will be
places on the dimension line by
breaking the dimension line -- this format is normally used for engineering type drawings, but is not used for architectural drawings
1=on -- dimensions always placed
above the dimension line --
this is the one to use for architectural drawings |
DIMTFAC
|
Sets height of tolerance text with
relation to main dimension text
height -- default is 1.0 Recommended value is 0.75 -- no need to be concerned about this variable, since tolerances are rarely used in architectural drawings. |

inside extension lines -- default is 1,
should be 0
0=off -- dimension text always
parallel with dimension line
1=on -- dimension text always
horizontal regardless of dimension line
orientation |

|
Sets whether text is always placed
between extension lines -- default is 0,
should be 1
0=off -- text will be placed to
the right or left side of dimension if it
does not fit between extension lines
1=on -- text will always be placed
between extension lines regardless
of whether it will fit -- this is more desirable for architectural drawings. If it becomes a problem with long dimensions overlapping dimensions, they can always be moved with the DIM<RET>TEDIT<RET> command sequence |

inside of extension lines, whether or
not text is drawn outside of extension lines -- default is 0, should be set to 1

dimension line if text is outside of
extension lines
1=on -- will force dimension line
to always be drawn between
extension lines |
DIMTOH
|
Sets orientation of dimension text
outside extension lines -- default is 1,
should be 0
0=off -- dimension text always
parallel with dimension line

horizontal regardless of dimension line
orientation |

Sets tolerance dimensioning --
default is 0, which is OK

and DIMTP are drawn
Tolerances are rare in
architectural drawings, and therefore this
variable is not normally used |
DIMTSZ
|
Dimension tick size -- default is
0.0
If set to some value other than 0,
dimension will have ticks drawn in
place of arrows -- if ticks are desired, this value should be set to 0.09. Arrows are recommended. |
DIMTVP
|

position -- default is 0.0
If set to 1.0 it is equivalent to
DIMTAD set to 1 (on); if set to -1.0,
