Interpretations Ribbon Tab

Commands available on the Interpretations ribbon tab, grouped by panel.

Move (ribbon key tip: I)​

Tooltip: Mouse interaction modes

Choose how mouse clicks interact with the 3D view.

Dropdown items:

  • Move Mode — Switch to Move mode
  • Interrogate — Interrogate the scene

View From​

Tooltip: View and rotation presets

Preset camera positions and rotation resets for the 3D view.

Dropdown items:

  • North — View from north
  • South — View from south
  • East — View from east
  • West — View from west
  • Above — View from above
  • Below — View from below
  • Centre In Model — Centre the view on the model
  • Reset to North — Reset heading to north
  • Reset Rotations — Reset all view rotations
  • Forward View — Look forward
  • Nadir View — Look straight down (nadir)

Active Descriptor​

The values given to new interpretation objects, and applied to selected ones. The lists behind them live in the Collections tree: Facies, Contacts and Units. See the Active Descriptor in the interpretation guide.

Facies​

Dropdown items:

  • Button — New facies
  • IDC_INTERP_FACIES_APPLY_SELECTED — Update all selected objects with this facies value
  • Facies — Active facies

Contact​

A contact is a picked boundary between two units.

  • New Contact — Create a new contact (a picked boundary) in the Contacts list.
  • Apply (IDC_INTERP_HZ_APPLY_SELECTED) — Apply the active contact or unit to the selected objects: the selected traces (polylines and faults) take the active contact, and everything else (orientations, geobodies, scan lines, stratigraphic units) takes the active unit.
  • Active contact (IDC_INTERP_ACTIVE_PICK) — The contact given to new polylines and, by Apply, to selected traces.

Unit​

A unit is the interval between two contacts.

  • New Unit — Create a new stratigraphic unit in the Units list.
  • Active unit (IDC_INTERP_ACTIVE_UNIT) — The unit given to new scan lines and, by Apply, to selected orientations, geobodies, scan lines and stratigraphic units.

Structure​

Dip Azimuth​

Tooltip: Dip and azimuth tools

Compute structural dip and azimuth using one, three or many points, an area, or from existing attributes.

Dropdown items:

  • 3 Points — Dip / azimuth from 3 points
  • N Points — Dip / azimuth from many points
  • 1 Point — Dip / azimuth from one point
  • Area — Dip / azimuth over an area
  • Attributes — Dip / azimuth from attributes

Digitse Fault​

Tooltip: Fault digitising tools

Create, split, join, extend or add sticks to fault interpretations.

Dropdown items:

  • New Fault — Start a new fault
  • Split — Split a fault
  • Join — Join two faults
  • Add stick — Add a fault stick
  • Extend Fault — Extend a fault

Digitise Polyline​

Tooltip: Polyline editing tools

Split, join, edit nodes, draw contours and snap polylines to the mesh.

Dropdown items:

  • Digitise Points — Digitise by individual clicks
  • Draw — Draw polyline with continual digitising on mouse move
  • Split Line — Split a polyline
  • Join Lines — Join two polylines
  • Add Node — Add a node
  • Draw Contour — Draw a contour
  • Create Geobody — Create a geobody
  • Close Polyline — Close the polyline
  • Snap To Mesh — Move the selected polyline onto the active mesh: each vertex goes to the closest point on the surface, and vertices are added along each segment at the polyline's sub-sampling distance (1 unit by default). Undo restores the line as digitised. See Snapping a line to a mesh (ID_POLYLINE_SNAPTOMESH)
  • Geodesic Distance — Click sparse points; the polyline follows the shortest on-surface path between them and shows the cumulative along-surface distance (ID_INTERPRETATION_POLYLINE_GEODESIC)
  • Texture Track — Click sparse points on a textured outcrop; between clicks the polyline follows the contact in the texture. Untextured surfaces fall back to the geodesic (ID_INTERPRETATION_POLYLINE_TEXTURETRACK)

Auto Tracker​

Tooltip: Auto-tracker options

Configure settings for the surface auto-tracker.

Dropdown items:

  • Settings — Auto-tracker settings

Scan Line​

Tooltip: Create a scan line for fracture intensity analysis.

Creates a linear fracture-sampling scanline in 3D space. A scanline is a straight line segment used to measure fracture frequency, spacing, and orientation-dependent intensity.

Dropdown items:

  • From intersections — Create a scan line oriented from displayed fracture orientations.
  • From Points — Digitise fracture positions manually along a scan line.

Plunge​

Tooltip: Measure plunge

Measure the plunge of a linear feature picked on the mesh.

Sticky Interp​

Tooltip: Sticky interpretation mode

When enabled, the active interpretation tool stays selected after each pick.

Sedimentology​

Geo Polygon​

Tooltip: Digitise with individual points

Digitise with individual points. Space bar to toggle continuous drawing..

Dropdown items:

  • Digitise Points — Digitise geopolygon with individual points.
  • Draw — Draw geopolygon
  • Key Pillar — Add pillar to geobody
  • Create from polylines — Create geobody from polylines

Measured Section​

Tooltip: Create a measured section/log

Start a new measured section or geological log along a digitised path on the outcrop.

Palaeocurrent​

Tooltip: Measure a palaeocurrent

Measure a palaeocurrent direction from a single picked point.

Borehole​

Tooltip: Create a borehole

Create a new synthetic borehole at the picked location.

Edit​

Move Vertices​

Tooltip: Move vertices

Click and drag to move polyline or fault vertices in the 3D view. Hold Alt while dragging to move the whole line with the vertex.

Pause Digitising​

Tooltip: Pause Digitising

Pause digitising to move the model around. Un-pause to continue

Undo​

Tooltip: Undo last action

Undo the most recent edit. The button is greyed when there is nothing to undo, and its tooltip names the step it would take. Its dropdown lists the recent steps, most recent first: pick one and every step down to it is undone. Undo is also on the Quick Access Toolbar by default, so it can be reached from any tab.

Most property-bar rows record a step, and a spinner's or slider's ticks on one row make one step. Dropdown, colour, font and file rows do not. Tree renames and drag-and-drop moves are steps too.

Up to 20 steps are kept, holding no more than 512 MB of saved mesh and point data; the oldest go first.

Redo​

Tooltip: Redo last undone action

Re-apply the most recently undone edit. It is greyed when there is nothing to redo, and it is on the Quick Access Toolbar by default too.

3D Translate​

Tooltip: Translate vertices in 3D

Move selected vertices freely in 3D using on-screen handles. Hold Alt while dragging a polyline or fault vertex to move the whole line. In the Vulkan view a press that misses keeps the gadget, Shift and Pause Digitising hand the left button back to navigation, and Esc disarms the tool. See The Edit panel.

Snap Vertices​

Tooltip: Snap Vertices

Snap digitised vertex to exisiting vertex if hit

Erase Vertices​

Tooltip: Erase Vertices

Erase Vertices from object

Reposition Object​

Tooltip: Click an object to select it. Click a new location on the model to determine its new location.

Move an existing interpretation object to somewhere else on the model: click the object, then click where it should go.
