TIP After specifying the desired settings, you can move or hide the Properties palette to expose more of the
drawing area.
11 Move the cursor over the grid so that the grid is highlighted and the list of column-add options is displayed.
(You press
Ctrl
to cycle through the options.)
12 Specify the insert point for the column on the grid.
Then… If you want to…
move the cursor over the node (or near it), and click. A
column is added to the node nearest to the cursor position. add a column at a particular node in the grid
press Ctrl, and click. add a column to all nodes in the grid
press Ctrl twice, move the cursor to the point where you want
to add the column, and click. If the Properties palette value
for Specify roll on screen is Yes, move the cursor to roll the
column around its extruded axis as desired, and then click;
or enter a value for the roll angle, and press ENTER.
A positive value rolls the column counterclockwise around its
extruded axis when viewed from its end (top) to its start
(bottom). add a column at a particular point on or within the grid
13 When you are finished adding columns to the grid, press
enter
to end the command.
NOTE Column grids that have numerous columns attached to them can take longer than expected to display
on screen. This is because structural members carry additional information that may be used for structural analysis.
Creating a Structural Member from Linework
Use this procedure to convert any of the following objects to structural members with structural member tools:
■
Arcs
■
Lines
■
Open polylines
■
Open polylines with arc segments
NOTE Converting an arc to a structural member is the only method of creating a curved structural member. For more
information about curved structural members, see
“ About Curved Structural Members ” on page 1412 .
When you use a tool to convert linework to a structural member, the style specified in the tool provides the shape of
the member. The linework defines the extrusion path for the shape. You can convert multiple lines to create multiple
members, convert curved lines to create curved members, and convert multi-segmented lines to create multi-segmented
members.
1 Open the tool palette that contains the structural member tool you want to use.
(You may have to scroll to display the desired tool).
2 Right-click a structural member tool, and click Apply Tool Properties to Linework.
3 Select the linework to convert, and press
ENTER
.
NOTE You cannot convert a closed polyline (a polyline with a start node that coincides with its end node) to a
structural member.
