| When designing polygons, i.e. copper areas, please adhere to the following rules: |
| 1. Use raster fill when designing polygons and try to avoid vector fill.
Incorrect: |
 |
| 2. When using vector fill, the recommended line width should not be less than 25µ. Line width of less than 0,1mm may, in many cases, lead the plotter program to freeze or to errors in curve interpolation.
Incorrect: |
 |
| 3. Do not combine polygons in the same leading layer using different filling techniques.
Incorrect: |
 |
| 4. Avoid hatched polygons. If necessary, ensure a minimum line width of 0.125 mm for the hatch pattern.
Incorrect: |
 |
| 5. When drawing negative polygons in positive mode, ensure that the polygon does not have any connections with a width of less than 1 mil.
Incorrect: |
