Converting IGES Line Styles
The IGES specification includes six standard line styles and custom line font patterns defined by line font definition entities (type 304).
Because Promis.e does not support custom line styles, the IGES line font patterns of entities with custom line font patterns can be mapped to any of the Promis.e line styles.
For IGES import, the default mapping of IGES line font patterns to Promis.e line styles is:
| IGES line font pattern | Promis.e line style |
|---|---|
| 0. Undefined | 0. Solid (SOL) |
| 1. Solid | 0. Solid (SOL) |
| 2. Dashed | 5. Short-dashed (SHD) |
| 3. Phantom | 6. Dash double-dot (DADD) |
| 4. Centerline | 7. Long dash-short dash (LDSD) |
| 5. Dotted | 1. Dotted (DOT) |
For IGES export, the default mapping of Promis.e line styles to IGES line font patterns is:
| Promis.e line style | IGES line font |
|---|---|
| 0. Solid (SOL) | 1. Solid |
| 1. Dotted (DOT) | 3. Phantom |
| 2. Medium-dashed (MEDD) | 2. Dashed |
| 3. Long-dashed (LNGD) | 2. Dashed |
| 4. Dot-dashed (DOTD) | 4. Centerline |
| 5. Short-dashed (SHD) | 2. Dashed |
| 6. Dash double-dot (DADD) | 3. Phantom |
| 7. Long dash-short dash (LDSD) | 4. Centerline |
Conversion between Promis.e line styles and IGES line font patterns can be customized:
