Creating a surface from polylines / contours

354 Views, 4 Replies

I am creating a surface from polylines and the surface is not being created per the what the polylines represent.  These are simple 5:1, 3:1, and 3.5:1 slopes.  The surface wants to create curves instead of straigtlines (see attached).  Does anyone have any clues what might cause this?  Thanks

what do the triangles look like? do you have any smoothing turned on?

It's probably just a smoothing option.

Try adding the polylines as breaklines instead of contours.

I agree with wfberry... it looks like a smoothing setting.
