-
- The DRAW LABEL command is used to create a label as a combination of an
- arrowhead, extension line and label text.
-
-
- COMMAND FORMAT
-
- #DRAW LABEL modifiers :Loc x1 x2 ... xn [:Loc ... ]
-
- Location 'x1' is used to define the position of the arrowhead for the label.
- The direction of the arrowhead is defined by the angle between locations
- 'x1' and 'x2'. The label extension line is drawn between all locations 'x1'
- to 'xn'. The label text is positioned at location 'xn'.

- MODIFIERS
-
- ARROWHEAD The ARROWHEAD modifier is used to select the type of
- arrowhead to be used. The modifier is followed by one of 3
- keywords to select the arrowhead type:
-
- CLOSED Use a closed unfilled arrowhead.
- FILLED Use a closed filled arrowhead.
- OPEN Use an open arrowhead ( < shape ).
-
- .LENGTH Requires a real value to specify the length of the arrowhead.
-
- ..RATIO Specifies the ratio between the arrowhead length and width.
- If the arrowhead length was entered as 5mm, a ratio of 2.5
- will make the arrowhead width 2mm.
-
- The above three modifiers can all be preset by using the SELECT DIMENSION
- command.
-
- POSITION POSITION is used to define how the label text will be
- aligned relative to location 'xn' and the last segment of
- of the label extension line. POSITION can be followe by one
- of two keywords:
-
- HORIZONTAL Specifies that the label text should be
- aligned horizontally. ( Default ).
-
- ALIGN Specifies that the label text should be
- aligned to the last segment of the label
- extension line.
-
- BUBBLE The BUBBLE modifier will cause the label text to be
- enclosed by a circle or bubble. Unless the DIAMETER modifier
- is used, the diameter of the bubble will be calculated from
- the length and height of the label text.
-
- .DIAMETER Used to specify a fixed diameter for the above option.
-
- TEXT The TEXT modifier is followed by one or more text strings
- each of which are used as successive labels are entered. At
- least one text string must be entered. ( See the command
- DRAW TEXT for the format of the TEXT modifier ).
-
- PARAMETERS The PARAMETERS modifier is used to enter a further family
- of modifiers used to control the text parameters and
- appearance.
-
- See the documentation for the command DRAW TEXT for a full
- description of the modifiers used to control text parameters.
-
- UNLINK By default, all of the entities that go to make up the label
- will be related as equal members. The UNLINK modifier can
- be used to suppress this.
