Command Overview

Fully define a 3D section by digitizing 3 points in any 3D window, updating the current section definition. Azimuth and inclination (and central position) are all derived from digitized point positions.

No additional screens display with this command.

Tip: right-clicking to snap section points to other data can be useful to ensure the section passes through data of interest.

Note: there are separate commands available to define the 3D view direction. These options are similar to defining a section (1 point, 2 points, 3 points) but in each case, no section definition changes, only the direction from which data is viewed in the target 3D window. See also Viewing Data and 3D Sections.

Command steps:

Orient your 3D view so appropriate data is clearly visible.
Run the command.
Following the prompt, select (snapping is allowed) 3 separate points in any 3D window (points can be digitized in combinations of windows if required).

The current section definition updates so that is passes through all three points.
