GEOPAK Place Turning Path

Question

I'm following directions found online for placing vehicle turning. When I left click to accept the first element the following message is generated:

MDL detected a divide by zero.; ALIGNMEN unloaded.

Any suggestions?

The solution was to run the analysis in a 2D file rather than a 3D file. Seems counter intuitive to have to use a 2D file in Powercivil but it works. Thanks to all for the help.
