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 MicroStation 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 MicroStation line styles.
For IGES import, the default mapping of IGES line font patterns to MicroStation line styles is:
| IGES line font pattern | MicroStation 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 MicroStation line styles to IGES line font patterns is:
| MicroStation 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 MicroStation line styles and IGES line font patterns can be customized:
