FunctionButton
Switches the structure selection order between bottom-
up and top-down.
BTM-UP/TOP-
DN
Switches the Reference Lock on and off. When the Refer-
ence Lock is on, you cannot select entities in an external
folder or view (more on this later).
R-LOCK
Switches the Selection Lock on and off. When the Selection
Lock is on, selection is restricted to the active edit target
and below.
S-LOCK
The next two exercises demonstrate the behavior of the BTM-UP/TOP-DN and
S-LOCK selection modes.
To select items when the selection mode is set to top-down
1 Press ESC to clear any selections.
2 Click the BTM-UP/TOP-DN button and ensure that the text on the button
reads TOP-DN.
3 Click one of the circles in Folder1:1. Note the tooltip indicates that you
selected the folder, Folder1:1, and not the circle.
4 Click the circle again. Note the tooltip indicates that you selected the
nested folder.
5 Click the circle again. Note the tooltip indicates that you have finally
managed to select the circle.
6 Click the circle again. Selection cycles to Folder1:1 again.
When the selection mode is set to top-down, the selection sequence begins
at the topmost level and ends with the elemental geometry. When the selection
mode is set to bottom-up the selection begins with the elemental geometry.
You may want to set the selection mode and repeat the exercise to verify the
behavior of the selection modes under the bottom-up.
