What did you do?

Offset isocurves generated from a planar surface.

What did you expect to see?

The curves maintaining the original plane of the surface.

What did you see instead?

One of the curves was offset in the Z axis. This doesn't match the coordinate system of the curve which further illustrates the issue with the inconsistency.

Fixed in Dynamo 2.10.

@sybold the fix will be available in release 2.10, which you probably don't have yet.
