The Elements/Geometry/Both button determines what the other buttons act on;
left-click the small triangular downward arrow to reveal a drop-down menu of
options. You can select Elements, Geometry, or Both.
Use the Display All, Display None, and Display Reverse buttons at the top of the tab
to change the display state of all assemblies, multibodies, components, groups,
system cols, load cols, and vector cols shown in the list.
All
displays and
None hides all of the items shown in the list/tree.
Display Reverse reverses the state of all the entities
(displaying the hidden, and hiding the displayed). If you have multiple link
entities selected in the
browser list, then
HyperMesh will only perform these actions on the selected entities. To
deselect all currently selected entities, left-click in any empty "white space"
within the browser list, such as between columns. To clear the selected entities in
the browser, make sure the browser is active, and then press
Esc.
Note: These buttons only affect the display state. They do
not actually remove entities from the model, but only show or hide them in the
graphics area.
