# Build units

From EDukeWiki

The Build engine has its own set of units termed "Build Units."

## Dimension

Build units expressed in terms of length, width, and height. One block of the largest grid size in Build editor equal to 1024.

The height scale is different. A z coordinate is 16 times that of x-y coordinates. In other words, a wall with 1024 of length equal in height for a value of 16384.

1024 units also equal to the default (non-stretched) size of an 64 pixels tile (i.e. pavement texture, ventilation duct texture, etc).

In real world proportions, 1024 units is around 2 meters / 6 or 7 feet. That scale is beyond that of a standing human (Duke or babes characters) and the usual size for doors height.

## Degree

For orientation in the rotational direction, the Build engine uses a 2048-degree scale (as opposed to 360 degrees.)

This means that a 90 degree angle is equal to 512 build units. In relation to the direction a sprite/actor is facing, a value of 0 means the actor/sprite is facing due East. The numbering goes up clockwise until 2047 (just counterclockwise from facing due East.)

## Time

Build units expressed in time. One second is equal to 30 Build engine time units.
