Issue using freehand polyline contour

[Chaznsc]

Good morning,

I have a weird intersection on a commercial site that I cannot model using a corridor. I decided to trace a controur, and use that as my defining element. In one spot, its defying me and shortchanging the contour. What am I doing to cause this and how can I correct it?

Thank you.

Two ways:

-Flip triangle faces to get it to look right in the surface.

-Use Featurelines to model the curb flowline

When you add the contour to the drawing, make sure you're a low mid-ordinate distance of 0.1 or 0.01. Also try changing your settings like swap edges

This intersection, as weird as it may look, can certainly be modeled using a corridor. I try to avoid faking in contours using polylines as issues such as this can arise. It also can be a headache when you need to make changes to your design. Can you post a clipped portion of your drawing (just this intersection)?
