I have a 3-D model using version 5.3 which I use to construct 3-D pathlines. Here is the sequence of menus/dialogs:

3D Options
Pathline ...

This starts the 3D Pathline Dialog box where the following options are selected:
    Start on 2D slice
    Backward
    Steady
    Multiple pathlines around well
    Start new pathlines ...

Upon selecting the well and drawing the pathline, I am presented a new option on the 3D pathline controller dialog box:
    2D projections ....

Pressing this brings up a new dialog, 2D Projections. I select
    Vertical plane defined by
    Segment (selecting a predefine line segment
    Show ...

FEFLOW shows the pathlines projected onto the vertical slice. Returning to the 2D Projections dialog, I press
    Save curves for diagram ....

This allows me to save all drawn pathlines a series of POW functions.

The question is: "What are the units of these pathlines?" They do not appear to be in global coordinates. Could they be in local coordinates? Or possibly a coordinate system related to the drawing?
