You can show graphical representations of node restraints, edges, master-slave
constraints, offsets, member hinges or gaps by clicking the ,
,
,
,
or
toolbar
buttons.
The arrow next to the node restraints button lets you choose between all restraints, normal restraints or the general restraint.
The arrow next to the edges button lets you choose between plate and
member edges. Showing plate or member edges makes them easier to see when
in rendered mode.
Turning on gaps also makes it easier to see the
edges of members and plates.
