Area selection

An Area selection is when the user draws a selection rectangle (mouse drag) in the viewport.
Use the following controls to select parts with Area selection:

Combinations

Description

Left-click
+
Selection area
Select only occurrences visible from the camera view and crossed by the selection rectangle
CTRL Key
+
SHIFT Key
+
Left-click
+
Selection area
Add to the current selection only occurrences visible from the camera view and crossed by the selection rectangle
SHIFT Key
+
Left-click
+
Selection area
Remove from the current selection only occurrences visible from the camera view and crossed by the selection rectangle
Right-click
+
Selection area
Select all occurrences from the scene crossed by the selection rectangle ("in-depth" selection)
CTRL Key
+
SHIFT Key
+
Right-click
+
Selection area
Add to the current selection all occurrences from the scene crossed by the selection rectangle ("in-depth" selection)
SHIFT Key
+
Right-click
+
Selection area
Remove from the current selection all occurrences from the scene crossed by the selection rectangle ("in-depth" selection)
Important
"In-depth" selection with the Mouse Right-Click will select all the parts comprised in the selection rectangle, including occluded parts (meaning entirely hidden by other parts). Contrary to selection with the Mouse Left-Click that will not select occluded parts.
Note
All parts crossed by the selection rectangle will be selected: they do not need to be entirely in the rectangle to be selected (one pixel is enough).
