Selection Sets, or NSS is a dialog box driven utility that enables you
to save selection sets to a file. Each selection set is given a name and
a description. Each selection set is highlighted when you click on
the name in the list. The selection set name and description can be
changed at any time. You can add or remove objects from any of the
selection sets, you can also delete a named selection set from the list.
Your named selection sets can then be saved to a file that is loaded
automatically each time Named Selection Sets is run. More importantly,
they are available each time you re-open the drawing. Named Selection
Sets can also be used as a transparent command, start any command that
requires a selection set, either click the toolbar button or type 'ddselset
at the command line to retrieve any named selection set in the list and
pass it to the running command. You could also create new named

Steel
Steel
is a dialog box driven utility for drawing structural steel sections in
either section, plan or front views. It is also possible to draw
non-standard sections by entering the section data via a dialog box.
When drawing a sectional view, you can select the point where the
section is drawn, this is either top, middle or bottom, an insertion
point is then picked and a rotation angle. When drawing either a front
or plan view, an insertion point is picked followed by an end point.
Apart from the full range of UK sections, we can also provide European,
USA and Japanese (JIS) section data. Sections can be drawn in either
metric or imperial units.
