Picking the cloud opens the Extract Section Lines from Point Cloud
dialog with the reference's settings and defaults: entire cross section
or perimeter only, maximum points to process (slider and field, with
the estimated time), output layer (Use Current or a layer), colour,
lines or 2D polylines with their width, minimum line length and connect
lines tolerance (each measurable by two points on screen), collinear
angle tolerance (0-10) and Preview result. Create extracts; with the
preview it asks [Accept/Settings/Undo] and Settings reopens the dialog.
The settings are kept for the session. Automation action pc_section.

The manager's switches write the cloud's hidden scans (by the scan
identifier its project and scan file carry) and hidden regions (the
unassigned points are region 0), as the reference stores them, instead
of extended data. A parent switch shows mixed while some of its rows
are on. A cloud that shows none of its points draws its extents box.
The codec reads and writes both lists.

A dockable Point Cloud Manager lists each point cloud of the drawing (only
the selected ones while any is selected) with Regions (disabled, region
data is not read), Unassigned Points and Scans, the scans named by their
file stems. Each switch shows or hides points: the cloud, its unassigned
points, all scans or one scan. The hidden set is the cloud's
OCS_POINTCLOUD_VISIBILITY extended data (scan names plus *CLOUD_OFF /
*UNASSIGNED_OFF markers, app id registered), written as one undo step and
kept on save. The drawn points skip hidden scans by their index ranges,
and the hidden set is part of the placed-cloud key. Collapse all / expand
all, row highlight and a search box that filters rows (keeping parents of
matches). POINTCLOUDMANAGERCLOSE closes it; the pc_manager_toggle
automation action flips a switch.

Planes are found from the cloud points under the pick and grown over
the connected points on them: two planes give a line along their
intersection over the points' extent, three a point at their corner.
A cylindrical segment gives a line along its axis. A live section
object traces the points on its kept side as polylines or lines in the
section plane, with a preview and Accept/Settings/Undo;
-PCEXTRACTSECTION creates them directly.
