Interpretation Tree
The Interpretation Tree lists what you create on the data — orientations, polylines, faults, surfaces, geopolygons, sections, sketches and flight paths. It is the Interpretations tab of the left panel.
Above the tree, a branch selector and Manage Branches button control interpretation version control. Only the objects in the selected branch and scenario are listed.
Branches
The branches appear in this order. Each is always present, except the three marked as conditional.
| Branch | What it holds | Under each item | Right-click reference |
|---|---|---|---|
| Orientation | Structural orientation measurements (bed, fracture, cleavage, foreset, regional), in groups. The first node, Attributes, lists the measurement table's columns. | — | Orientation, Attributes |
| Scan Lines | Fracture scan lines: fracture positions logged along a line for spacing and intensity. | — | Scan Lines |
| Palaeocurrent Group | Palaeocurrent vectors. | — | Palaeocurrent |
| Log Elements | Individual log units placed in the 3D view. Empty in most projects. | — | Log Elements |
| Measurements | Distance and area measurements. | — | Measurements |
| Polylines | Digitised lines — bedding traces, fracture traces, contacts — in groups. The first node, Attributes, lists the polyline table's columns. | — | Polylines, Attributes |
| Faults | Fault objects, in groups. | — | Faults |
| Flight Path | Camera fly-throughs. | Viewpoints, Points of Interest, Scenes, Slides | Flight Path, Viewpoint, Points of Interest, Scenes, Slides, Slide image |
| Surfaces | Geosurfaces: surfaces gridded or triangulated from interpretations. | Attributes | Surfaces |
| Geopolygon | Geobodies: closed polygon outlines of bodies drawn on the outcrop. | Key Pillars | Geopolygon |
| Stratigraphic Units | Stratigraphic units: the interval between a younger and an older contact, built from the polylines that trace them. Called Zone in earlier versions. | — | Stratigraphic Units |
| Drone Surveys | Drone flights planned over a mesh, to photograph it again at a finer resolution. Made with Plan Drone Survey on a mesh in the Data tree. | — | Drone Surveys |
| DFN (licence: DFN) | Discrete fracture networks. | Attributes | DFN, DFN Attribute |
| Discrete Element Model (licence: DFN) | Particle-based discrete element models. | Attributes | Discrete Element Model |
| Variograms | 3D directional variograms of an attribute, made with Variogram 3D on a mesh or point cloud. | — | Modelling Grids and Variograms |
| Sections | Cross-sections. | — | Sections |
| Sketch Layers | Sketch layers, each holding freehand sketches. | sketches | Sketch Layers |
| Time Series (developer builds only) | Time series of repeat surveys. | — | Time Series |
Shared menus
Scan Lines, Palaeocurrent, Log Elements, Measurements, Flight Path, Surfaces and DFN show the standard group menu on their header, and several of them show the standard item menu on their objects. Both menus, and the list of who uses them, are on the Standard Item and Group Menus page.
Not in the Interpretation tree
- Viewpoints and scenes used outside a flight path live in the Collections tree.
Interactions
- Tick an item or a group to show it in the 3D view.
- Set Focus on a group makes it the target for new interpretations; it is shown in bold.
- Group a selection to make a new group, and drag items between groups.
- Double-click an object to navigate to it.
The behaviours common to all three trees are on the Project Trees overview.
