BLNK                                                               Menu: SUTIL
==============================================================================
Temporarily displays only entities included in the selection group.

Description:
This command temporarily erases all non-selected entities from the screen.
Only the entities and instances (placed objects) included in the selection
group are displayed, and you may continue working on the model. To display the
rest of the model, invoke the \nblnk command. Commands that create a solid
body (such as \solid) and those that create a plot file (\plot) or an external
file (\dxfo) operate only on the part of the model that is displayed.
Note that if you temporarily use the command for wall axial lines, you will
later have to fix intersections with added walls.

        Example: \blnk
        Result:  The part of the model that is not selected temporarily
                 disappears from the screen.
