Answer:
In SHAPE‑THIN 9, you can open the cross-sections that were created with the following program versions:
- SHAPE-THIN 5.xx
- SHAPE-THIN 6.xx
- SHAPE-THIN 7.xx
- SHAPE-THIN 7.5x
- SHAPE-THIN 8.xx.
- SHAPE-THIN 9.xx
To open the cross-sections, you can use Project Manager (Image 01) or the menu "File" → "Open" (Image 02).
The cross-sections from the DOS versions SHAPE‑THIN 1.xx and SHAPE‑THIN 2.xx cannot be imported into SHAPE‑THIN 9.
