How to flip 3D polyline arc?

[jlmJRVB8]

Hello, 

I am trying to flip or reserve an arc direction in Civil 3D. The points were shot using a BC and EC and they have imported the 3D polyline concave to the East and it should be concave to the West. Is there a way to reserve this arc without exploding the 3D polyline and manually drawing the arc?

Thank you so much in advance!

How about double click the 3dpoly line and choose the option reverse on command prompt?

If its an ARC make sure convert the same to 3dpoly/2d poly and then double click it and select reverse option it will change the direction.

Hope this will be helpfull.

Are you sure that you are talking about a 3d Polyline? Or are you referring to a featureline? 3D Polylines cannot contain arcs.
