ORD Active3dByPlanProfileRule

Under the Properties for Elements in ORD there is an area titled  Active3dByPlanProfileRule.  I am at a loss as to what some of the variables mean.  Are the variables listed in the help somewhere?  I am endeavoring to do some site modelling.

1. Curve Stroking

2. Horizontal filter

3. Linear Stroking, 0 does work sometimes for endpoints.

4. Profile stroking, I think similar to above

5. StrokingMethod, 

6. Stroking Step Method

7. Vertical Filter
