**/DIST**
**/DIST**, `WN`

, `DVAL`

, `KFACT`

**Specifies the viewing distance for magnifications and perspective.**

**
**`WN`

Window number (or ALL) to which command applies (defaults
to 1).

**
**`DVAL`

Distance along the view line from the observer to the focus
point (defaults to value producing full-window display). Distances "too close"
to the object will produce excessive magnifications. If `DVAL`

=
AUTO, zero, or blank, the program will calculate the distance automatically.
If `DVAL`

= USER, the distance of last display will
be used (useful when last display automatically calculated distance).

**
**`KFACT`

`DVAL`

interpretation key:

**0**
| — | Interpret numerical `DVAL` values
as described above. |

**1**
| — | Interpret `DVAL` as
a multiplier on the current distance (`DVAL` of 2
gives twice the current distance; 0.5 gives half the current distance, etc.). |

### Command Default

Distance is automatically calculated to produce full window magnification.

## Notes

The scale factor is relative to the window shape. For example, for
objects centered in a square window and with parallel projection (no perspective),
a distance of
/2 (+10%) produces
a full window magnification, where
is
the largest in-plane vertical or horizontal dimension. See also **/AUTO** and **/USER** commands.

This command is valid in any processor.
