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 OpenBuildings™ Station Designer 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 OpenBuildings™ Station Designer line styles.
For IGES import, the default mapping of IGES line font patterns to OpenBuildings™ Station Designer line styles is:
| IGES line font pattern | OpenBuildings™ Station Designer 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 OpenBuildings™ Station Designer line styles to IGES line font patterns is:
| OpenBuildings™ Station Designer 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 |
