Suppose you have a line body and want to have two points at specific locations, such as where the profile (cross-section) changes near each end from the more slender middle to the thicker ends. In SpaceClaim, create a plane normal to the line at each end. Use the Move tool to slide the plane a specific distance. Use the Split Body tool to cut the line into three pieces. On the Workbench tab, use the Share button to ensure that the mesh will connect the three pieces back into a single structure that can have different profiles.
