- 5.8.1 DRAW XHATCH
-
-
- The DRAW XHATCH command is used to define a closed polygon which will be
- filled with evenly spaced parallel lines to denote cross-hatching. The
- entity created is called an xhatch polygon. A single xhatch polygon may
- consist of up to 64 separate polygons, one main polygon and 63 sub-polygons.
- Sub-polygons can be used to define inner boundarys within the main polygon
- that act as 'holes' and will be excluded from the cross-hatch fill.
-
-
- COMMAND FORMAT
-
- #DRAW XHATCH [modifiers] :Loc x1 x2 ... xn [:Loc x1 x2 ... xn] [CR]
- Loc ...
-
- The first set of locations entered define the main polygon boundary. If this
- set of locations is delimited with a colon, then a sub-polygon boundary
- definition can be entered. Futher sub-polygon boundaries may be entered
- until a return is used to terminate the last location list. When the xhatch
- polygon has been created, a second xhatch polygon can be defined in the
- same way. To terminate the command, a return should be entered at the 'Loc'
- prompt which appears when the previously defined xhatch polygon has been
- created.
-
- Cross-hatching is generally drawn using existing entities to define the
- boundary of the area to be filled. To create a polygon boundary using existing
- entities, the IDENTS point on entity modes - CHAIN, GENERATE, END, MID, ORG
- and NEAR - can be used to generate the required boundary. For more
- information on this subject see the documentation for IDENTS or use the
- command:
-
- #HELP MANUAL IDENTS LOCS
-
- ( See figs. 5.54 to 5.56 ).

-
- MODIFIERS
-
- LAYER Requires a layer number. This will override the current
- active layer.
-
- DEPTH Requires a depth number. This will override the current
- active depth.
-
- DISTANCE The DISTANCE modifier is used to specify the spacing of the
- parallel lines used to denote the cross-hatch. A value must
- be entered for this modifier.
-
- ANGLE The ANGLE modifier is used to specify the angle for the
- cross-hatching. If the modifier is omitted, the default
- angle of 45 degrees is used.
-
-
- Like most entities, xhatch may be drawn with a hardfont or a softfont.
- The font will be applied to each of the lines that make up the cross-
- hatching.
-
- HARDFONT Indicates that a hardware line style will be entered.
-
- .STYLE One of the predefined styles, a value between 0 and 15.
-
- .THICKNESS Line thickness, a value between 1 and 5.
-
- SOFTFONT Indicates a software line style will be entered. For a full
- description of the SOFTFONT option, see the documentation
- for the command DEFINE SOFTFONT.
-
- ATTRIBUTE Used to enter one or more attributes associated with this
- entity. For a full description of the ATTRIBUTE option, see
- the documentation for the command ADD ATTRIBUTE.
