Description

Activates line selection mode. If line selection mode is already active, running this command will have no effect.

Line selection mode is a modal switch that sets the left-hold-drag data selection behaviour in all 3D windows (the same behaviour will be exhibited in all viewports).

'Line selection' refers to the method by which data is selected. Once active, left-clicking and holding the left mouse button down allows you to drag a line of a fixed width across the 3D screen, capturing all data that is either wholly captured by the selection shape boundary or any data that fully or partly overlaps the selection area (depending on your data selection settings).

After the first left-click, you control the length and orientation of the selection 'line' (actually, a rectangle) using mouse movement.

The 'sml' quick key combination can be used to quickly alternate between line and box selection modes.

For example, in the image below, left-clicking and holding at point (1), then dragging to point 2, allows a single drillhole to be selected. In this case, data selection settings are such that data has to be fully encapsulated within the selection area to become selected:

You can control the width of the selection line using the mouse wheel between points (1) and (2). The selection width is maintained for future selection events.

How to use

Display and orient data so that data for selection is clearly seen.
Run the command selection-line-mode-switch or the quick key combination 'sml'.
Left-click and hold at the start of the selection line.
Use the mouse wheel, if required, to set the width of the selection line.
Left-click the second point to select data according to current selection settings.
