Perform Parametric Trimming
Use the Split/Stitch tool to restore suppressed fixed points.
Note: FE geometry is supported for this tool, except
                for unsuppressing fixed points using Ctrl +
                left-click.
        - 
                From the Topology ribbon, click the Split/Stitch tool.

                From the guide bar, select
                    Split.
                Tip: You can use the keyboard shortcuts underlined in the function name to select a function.
 - Optional: 
                From the guide bar, select Lines
                    to split a line into separate segments at a joint.
                Joints exist where lines have been previously combined, or where geometric features dictate. Joints are part of the line definition history, so depending on how the line was created, it may or may not have joints.
- Select the input line.
 - Click any of the displayed joints to split the line at that location.
 
The split will be made automatically. -

Tip: Use snap points to create fixed points at predefined points on your
                model such as end, middle, and center points.
