Object Selection

	Control	Behavior
Select single object	double-left-click on object	Selects clicked on object and deselects all other objects. If the object is part of a group, the whole group is selected. Bounding box and slight glow indicate object is selected.

Transformations

For all transformations:

• In order to transform an object you must first select it.
• Hold ctrl to make movements snap by discrete increments.
• Hold alt to transform a clone of an object (or multiple objects), leaving the original object behind
• Left-click controls a 'generic' version of the transformation; right-click controls a version of the transformation contextually specific to the clicked on face. Holding shift locks the transformation to a single axis.
• Groups are transformed about the group center. Ungrouped objects, even if multiple are selected and transformed at once, are transformed about their own individual centers.
