Geologic Interpretations

You are here:

Geologic Interpretations

On the Target tab, in the Subsurface Tools group, the Geologic Interpretations tools can be used to create, modify and view geologic interpretations (drawings) as well as to create and modify the feature classes that store and organize these drawings. You can then easily share the subsurface geology interpretations that you created with your colleagues.

The following options are available under the Geologic Interpretations drop-down button:

Create Feature Class allows to create a new Geologic Interpretations Feature Class in the current drillhole dataset.
Modify Attributes allows you to modify the rock type attributes stored within a feature class.
Draw on Sections allows you to draw geologic interpretations on section views. Enabled once a Geologic Interpretations Feature Class is added to the current Scene and at least one Section exists in the current drillhole dataset.
When you select Draw on Sections:
- The Section View tool for the current Scene is enabled.
- The Edit mode in the ArcGIS Pro editing tools is turned on.
- The Create Features side panel opens and shows the Templates tab. This sets up the environment to begin drawing: select one of the attributes listed in the Feature Templates, click a construction tool or use the default tool, and start drawing. To finish the feature, right-click and click Finish. On the Edit tab, in the Manage Edits group, click Save then Clear to remove the selection.
  The drawings will be captured in the section plane.
Draw in 3D Scene allows you to draw geologic interpretations in a Scene. Enabled once a Geologic Interpretations Feature Class is added to the current Scene and selected.
When you drop down the Geologic Interpretations button and select Draw in 3D Scene, the Create Features side panel opens. In this mode, you will be able to draw directly in 3D space, which means snapping to any existing objects in the Scene:
- On the Edit tab, in the Snapping group, click the Snapping drop-down menu and choose your snapping preference.
- In the Create Features pane, in the Templates tab, select the feature attribute or 'rock type' to create via drawing/editing. Start drawing (click a construction tool or use the default tool); to finish the feature, right-click and click Finish. On the Edit tab, in the Manage Edits group, click Save then Clear to remove the selection.
Edit Drawings allows you to edit the geologic interpretations that you have created: you can change/adjust the shape of the drawings, delete a shape that isn't correct, or change any of the assigned attributes (rock types) that might have been wrongly selected at the start. You may also need to delete a shape and re-draw it.
When you drop down the Geologic Interpretations button and select Edit Drawings, the Modify Features side panel opens. In this state, you can select the (polyline or polygon) feature containing the drawing and edit the vertices to change the shape of the drawing, delete the drawing, or change the assigned attribute:
- Edit Vertices: press the button in the Modify Features pane to add, move, or delete vertices and segments from the selected feature. Hover over the vertex location until you see the circle mouse cursor, then double click. This shows a 3-headed arrow that you can drag to move the vertex in 3D space.
- Delete the entire shape using the Delete button on the Edit tab or using the Delete key.
- Change the assigned attribute, by opening the Attribute Table (from the Data toolbar): in the Attribute table, locate the selected row, which corresponds to the selected shape, and change the value in the 'DH_RockType' column.
View Drawings allows you to control the display of the interpretations that are saved with a feature class and to view and assess the quality of your interpretations.
