(they are the same)
The script works now with intersections in any direction (swithch from scale to extend line). Also handles somehow geometries that have holes inside and finnaly some little extra options added (you can choose to extend the split line or not, material thickness).
Also, there is one think to keep in mind when using the scripts. You will sometimes get errors when using a too low absolute tolerance in Rhino. So go to Tools>Options>Units and set Absolute tolerance to 0.0000001 or something absurdly accurate.
