Re: Offset Problem 2013

Well.... It might alert them to the problem. You can attach a small drawing or ask for a link to upload a larger on, so they'll be able to see your examples. I've had mixed results with SRs, but it's worth a try.

 

BTW. I don't have 2013 so I can't look at your examples.

You might try using the Express Tools Offset command.  EXOFFSET

Were the lines you are having trouble with imported from survey data? I usually explode those feature lines, convert them to 2d polylines and flatten them to zero elevation. Then I don't have problems with offsets of curb lines, etc.

I was trying to draw new medians in an existing road.  I drew a polyline on top of the survey figure for the edge of pavement, snapping to the end points of the figure(s). I then set the polyline to 0 elevation. Then I offset each side inward by 13.5' for my outside lanes and that told me what the outside edges of my new median would be. The problem was that after I connected the two edges together and made a single polyline that when I'd go to offset it 0.5' inward to create the BOC that I ran into the problems. 

 

To get the existing edge of pavement, face of curb, and back of curb we use the survey codes to do that automatically so we don't have to draw them. Works great and makes it much faster to get a surface. We never explode a survey figure as that leads to problems later on for us.

I know this thread is a little old but I just had the same problem and found it. I didn't get much help from any of the results I was finding so I went back to try some more things on my own. When I used the OVERKILL command and ran it on the two lines I was having problems with, BAM. Now I can offset them. Just wanted to share this since it may help someone in the future.

I had a pretty complex closed polyline of a river.  It had over 7000 verticies.  I used OVERKILL on it but it finally worked with I used WEEDFEATURES.  I had to try a couple of times to get it simplified enough.

Another option would be to use Map Drawing Cleanup to remove pseudo nodes.
