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 |
