  Structural Brace tools located on the Design tool
  palette each include a shortcut menu option to
  convert linework to the structural member.
• Therefore you can draw an arc, line, or polyline
  and convert the geometry to a structural member.
  The linework becomes the axis line for the
  structural member.

• Clipping a column grid allows you to only see
  that part of the grid, which is inside the closed
  polyline.
• The clip can be applied when the grid is inserted
  or added to an existing grid.

41

• Columns can be inserted at each intersection of
  the column grid by selecting a style from the
  Style drop-down list in the Properties palette as
  shown at right.
• The content of the drop-down list includes the
  structural member styles created from the
  Structural Member Catalog and used in the
  drawing.
• The column style will be inserted at each
  intersection of the column grid, however you can
  erase selected columns from the grid.
• The properties such as logical length, start
  offset, end offset, justify, and justify using
  overall extents are set in the Dimensions section
  of the Properties palette of the column grid.
