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