==============================================================================
Measures an angle between three points.

         1.* (POINT) vertex of angle
         2.* (POINT) first point
         3.* (POINT) second point
         4.* (POINT) position point of arc

Description
This command calculates the angle between three points on or parallel to any
of the major planes.

As a result of this command two new entities will be created:

a text string indicating the value of the angle measured, in degrees

an arc from the first point to the second point the angle of which depends on
the position point of the arc parallel to the current working plane at its
current value

The vertex of the angle will be the center point of the arc.

Point to the vertex of the angle (if necessary by the construction of help
lines) and then point to the two points.

Point to the position for the arc.  This point determines the location of the
arc symbol.

NOTE 1:This command may be operated only on orthogonal views of the model
(xy/xz/yz) and all three points indicated must be on the same plane.

Both the text and arc may be independently manipulated, updated or deleted.

The arc and text entities will be of different data types (e.g., text = `1',
arc = `5') but of the same application `6' (dimensions line).  Thus, both of
them may be added to a selection group of application type `6' (\apsel 6).

The arc and text entities receive the attributes currently set for dimension
lines and text respectively, except for justification and format.  The default
justification for the text is according to its position around the arc, and
the default format is a value in degrees with an accuracy of up to one place
after the decimal point, followed by the symbol for degrees.  Line attributes
of the arc and text attributes of the text may be updated by the commands for
updating dimension lines (except justification and format).  The text
justification may be updated by the command \utjst.
