Runner Bodies / Other Cross-Section
When choosing the type of cross-section for the runner, if the standard cross-sections are not appropriate, press the Other Cross-Section button 
to define any 2D closed sketch from the display area, on the ZX or ZY plane.
Defining another cross-section shape for the runner
The "other cross-section" should be prepared in advance before creating the runner objects.
The cross-section is a closed sketch, created inside the Runner Part.
The cross-section must be attached to the UCS of the runner part. Best results will be achieved if the cross-section is symmetric to the UCS.
The cross-section should be created on a plane that is normal to the pattern sketcher.
The option Revolved End requires a symmetric cross-section. Non-symmetric geometries (for example, a round/chamfer on one side) should be created on the completed runner body.
