/**
|
|
* @brief The base class for placeable group of DocumentObjects. It represents a local coordnate system
|
|
*
|
|
* This class is the FreeCAD way of representing local coordinate systems. It groups its children beneath
|
|
* it and transforms them all with the GeoFeatureGroup placement. A few important properties:
|
|
* - Every child that belongs to the CS must be in the Group property. Even if a sketch is part of a pad,
|
|
* it must be in the Group property of the same GeoFeatureGroup as pad. This also holds for normal
|
|
* GroupExtensions. They can be added to a GeoFeatureGroup, but all objects that the group holds must
|
|
* also be added to the GeoFeatureGroup
|
|
* - Objects can be only in a single GeoFeatureGroup. It is not allowed to have a document object in
|
|
* multiple GeoFeatureGroups
|
|
* - PropertyLinks between different GeoFeatureGroups are forbidden. There are special link properties
|
|
* that allow such cross-CS links.
|
|
* - Expressions can cross GeoFeatureGroup borders
