Measures an angle between two lines.

         1.* (IND) first line
         2.* (Y/N) confirm choice
         3.* (IND) second line
         4.* (Y/N) confirm choice
         5.* (IND) position point of arc

Description

This command calculates the angle between two lines.

As a result of this command two new entities will be created in the file: a
text string indicating the value of the angle measured, in degrees an arc from
the first line to the second line, the angle of which depends on the position
point of the arc.

In the case of continuous intersecting lines, the arc will be displayed
between the two lines through the position point.  Where the two lines
indicated do not intersect, the arc will be displayed between imaginary lines
produced from the lines to the intersecting point.

Indicate and confirm the two lines.  Point to the position for the arc.  The
position of 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).

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

The arc and text entities are 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.  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.
