On the ribbon, select Sketch in the Cross-Section list.
-
On the ribbon, click Cross-Section .
-
Click a point for the first segment. Then, decide what type of segment you want, and follow the corresponding link.
Define a line
Define an arc by three points
Define an arc by end points
Define an elliptical arc -
Click to place other segments of the cross-section as needed.
-
Click the starting point of the cross-section to close it.
-
Click Finish. The Finish button is not available until you close the cross-section by clicking the starting point.
-
You must sketch the cross-section on the two-dimensional plane that is orthogonal to the first leg of the path. The software displays this plane, which is perpendicular to the path, as you sketch the cross-section.
-
The cardinal point, which is the point at which the cross-section is attached to the path, is defined as you sketch. In other words, the cross-section surrounds the path and is attached to the path exactly as you sketch it.
-
If you sketch a cross-section, the properties for the cross-section include coordinates, turns, and related turn values, if applicable.
