Use this procedure to convert any of the following objects to structural members with structural member tools:
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.
(You may have to scroll to display the desired tool).
A worksheet opens appropriate to the tool you selected.
If you created a structural member by converting a polyline, the initial orientation of the structural member is set to the UCS that was current when you drew the polyline. You can change the orientation by adjusting the Roll property of the member.
