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?</P><P>&nbsp;</P><P>Thank you so much in advance!</P> Thu, 13 Feb 2020 14:00:46 GMT https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9315917#M103241 jlmJRVB8 2020-02-13T14:00:46Z Re: How to flip 3D polyline arc? https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9318587#M103242 <P><a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/8437870">@jlmJRVB8</a>&nbsp;</P><P>&nbsp;</P><P>How about double click the 3dpoly line and choose the option reverse on command prompt?</P><P>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.</P><P>Hope this will be helpfull.</P> Fri, 14 Feb 2020 13:36:07 GMT https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9318587#M103242 Neil.Aryan 2020-02-14T13:36:07Z Re: How to flip 3D polyline arc? https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9318866#M103243 <P>Are you sure that you are talking about a 3d Polyline? Or are you referring to a featureline? 3D Polylines cannot contain arcs.&nbsp;</P> Fri, 14 Feb 2020 14:49:41 GMT https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9318866#M103243 hippe013 2020-02-14T14:49:41Z Re: How to flip 3D polyline arc? https://forums.autodesk.com/t5/civil-3d-forum/how-to-flip-3d-polyline-arc/m-p/9330010#M103244 <P>Hi&nbsp;<a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/8437870">@jlmJRVB8</a>&nbsp;</P> <P>&nbsp;</P> <P>Did the response above help answer your question?
