rotational blend



A rotational blend is created by sections that are rotated about the Y-axis. You enter angular dimensions to control section orientation and can dimension sections from their Sketcher coordinate system to control radial placement. You must add a section coordinate system in Sketcher mode. You cannot use the default coordinate system.

If you define a rotational blend as being closed, Pro/ENGINEER uses the first section as the last section and creates a closed solid feature. There is no need to sketch the last section.
