Starting with version 10.0.1.2948 of OpenGround Professional, inclined boreholes can be displayed on Quick Sections.
Boreholes are drawn based on data from the Orientation and Inclination group.
For details, see the Inclined Boreholes Guide, but in short:
- Orientation = degrees clockwise from North
- Inclination = degrees from horizontal, positive downward
Key Behavior
- Only a single Orientation and Inclination entry is used when drawing boreholes in Quick Sections.
- If a borehole has multiple orientation/inclination records, only the top-most record is used.
- If an inclination is provided but orientation is blank, a default orientation of 0° (North) is assumed.
Example Boreholes
| Borehole | Description |
| BH1 | Inclination = 90° → Drawn vertically down. |
| BH2 | No orientation/inclination data → Defaulted to vertical down. |
| BH3 | Orientation = 90°, Inclination = 30° → Drawn at an angle, roughly parallel to the section line. |
| BH4 | Two entries (deviated borehole) → Only top record used: Orientation = 270°, Inclination = 10°. Drawn accordingly. |
| BH5 | Inclination = -70° → Drawn upward (e.g., drilled in a tunnel or rock face). |
| BH6 | Orientation = blank (defaults to 0°), Inclination = 30° → Since it's perpendicular to the section line, it appears vertical but shorter. (For comparison, BH6 has the same true length as BH1.) |
Appearance of Inclined Boreholes
The visual angle of an inclined borehole in a Quick Section may appear less steep than expected. This is influenced by two main factors:
1. Vertical Scale Exaggeration
Most sections use a vertically exaggerated scale (e.g., 10× vertical vs. horizontal).
- This causes inclined boreholes to appear closer to vertical on the section.
- The greater the exaggeration, the steeper the borehole appears.
2.Orientation Relative to Section Line
- A borehole parallel to the section line will appear at its true inclination angle.
- A borehole perpendicular to the section line appears vertical, though visually shortened (e.g., see BH6 above).
