I draped a short string on a bridge deck., to optain the existing levels and slope between the two points. I want to extend that string at the slope(that was between the first 2 points) to a string crossing the string any distance away.
I my problem there is a intersection next to a bridge crossing the access road. I need to filled the strings to form a bellmouth, but I need to extend the existing bridge level to the road that is approximately 20m away.
I would apreciate it if I can be guided to to it both with the menus and with linemode.
Thanks

InfraTools in the Bonus tools has an extend string utility. Also you can write a macro or input file to extend string with 1000m or more (if needed) and trim the string to intersection with another string using EDIT and subsequent minors.
If you work with XM/V8i (has CAD environment) you can draw a line between the 2 points extend it wherever you need it then turn it into a string.
Either method you use I recommend adding a point to the line/polyline/string and keep the original points, obtained by draping.
Good luck,
