- Fills a polygon with a predesigned pattern.
-
- 1. (CHAR) name of fill pattern (1-8 char.) (<ENTER> for pull-down lib.)
- 2. (NUM) color of pattern (<ENTER> -original color)
- 3. (NUM) scale factor (greater than 0)
- 4. (POINT) origin
- 5. (POINT) point for direction
- 6.* (IND) polygon to fill (press <ENTER> for NEW origin)
- 7.* (Y/N) confirm choice
-
- Description
-
- This command fills polygons with patterns. A pattern is any system file saved
- either in your current directory or in the \ARCALIB directory.
-
- Identify the fill pattern either by its name or using the pull-down library
- (press ENTER for the pull-down library).
-
- Specify a color for the pattern or press ENTER to use the original pattern
- color. If the original pattern consists of two colors, both will be changed
- to the specified color.
-
- Enter the scaling factor (greater than 0), then indicate the origin point and
- a direction point for the fill. Indicate and confirm the polygon to fill (the
- procedure may take some time) or press ENTER for a new origin point.
-
- To halt the drawing of the pattern, press Alt+Shift simultaneously.
-
- A pattern is a set of polygons, so it may be selected using option `a' (hatch)
- in the \apsel command. The patterns can be created on any plane.
-
- The system repeats the prompt requesting a polygon to fill until you enter a
- new command. You may press ENTER to define a new origin point and direction
- point if you indicated them incorrectly.
-
- If your scaling factor is larger than 1 (the original pattern definition)
- and the polygon to fill is smaller than 1, only part of the pattern will be
- included in your polygon. Therefore, it is important to relate to the
- dimension of the pattern.
-
- The polygon to fill may contain inner or outer loops created using \pjump.
-
- To define the pattern, create a motif using the system. You may use any
- system entity, i.e., lines, polygons, etc., except arcs. If you want to set
- spaces between each repetition of the basic pattern, you can create a
- `control line' (line type 4) parallel to the X and/or Y axes, at the
- requested distance from the pattern to the start point of the next
- repetition of that pattern.
-
- You may now add your pattern to the system pattern library (named L$FILPAT)
- by saving the file under any name (\save command) and then using the \olib
- command (option `a' or `e'). For the file description, it is recommended to
- type the pattern dimensions in order to reference a factor. The pattern files
- may be located either in your current directory or in the \ARCALIB directory.
-
- The next time you display the pull-down library it will contain the newly
- added fill patterns.
