Rebuild

Rebuilds existing zone objects.

Command Operation

  1. select zone object(s)
  2. launch command
This command erases selected zone(s) then re-creates it/them again 'from scratch'.

Steps of rebuilding

The point is that it is possible to manipulate a zone using native SketchUp tools (move, rotate, scale), but after such manipulation some information stored in zone's properties becomes irrelevant (for example, area and perimeter will not match actual zone object's size after scaling a zone).
It is also possible to manipulate elements inside zone group (area element, wall element(s), ceiling element etc). 'Rebuild' command takes in account results of manipulations with 'area' element only and discards all other manipulations' results. So it is possible to launch 'Rebuild' command in order to 'undo' undesirable changes of internal zone's elements if any.
Since ver. 1.2.0 it is possible to create zones just by picking one single point inside a closed space in an active model. Rebuilding of such kind of a zone goes on a bit differently.

Steps of rebuilding of a zone, which has internal point

This method allows to take in account changes of actual geometry in an active model, which forms closed space where zone being rebuilded is located. It is necessary to pay attention to a tiny cross, which represents an internal point. This mark should be placed inside a closed space at room's floor level.

WARNING!

It is necessary to ensure that bounding geometry is actually visible before performing a rebuilding of such kind of a zone, because contour tracing procedure traces only visible things (i.e. WYSIWYG flag is turned on).
Note that this limitation not only a limitation, because it allows to hide things, which are not a part of contour to be traced (furniture, equipment, wall hanging light fixtures etc) before tracing.

Note

In addition to attributes refreshing 'Rebuild' command re-attaches labels with new relevant information (area, perimeter, floor level etc) if any.
In case if it is necessary to preserve manually made changes of zone group internal elements (wall, floor, ceiling, opening elements) and refresh zone's quantitative attributes, which depend on mentioned elements, then 'Recalculate' command should be used. 'Recalculate' command leaves geometry of zone group and its elements intact in contrast with 'Rebuild' command, but it refreshes quantitative attributes of a zone either.
