Offset FG in profile to represent pipe at constant cover

[Westhills]

I know it  can be done usign Pipe networks and feature lines and a massive waste of time.. But I just want ot offset my FG to show a line constant offset. Can this be done? If so how?

piece-of-cake: copy fg layout profile >> lower to top of pipe>> copy >> lower to invert.

you can do the same if it is a surface profile. (make static first)

Copy your FG profile.  Change the copied profile to Static in the properties, then you can raise or lower that profile.

Sorry Joe, must have been typing while yours submitted.

Great minds ...

Too easy. Thanks!

Only other thing was in doing that it created a copy of the alignment etc which I then had to delete.

If you use the "CopyProfile" command in the Profile geometry editor toolbar you wouldn't (or shouldn't anyway) see this problem.

Resurrecting an old thread.

When you copy down a profile, it’s not a true 'offset' profile. This is defiantly noticeable on steeper grades. An 8" DI pipe @ a 35% grade copied down 0.75' will yield a vertical distance of 0.75', but is only 0.71' perpendicular. The perpendicular distance is how the pipe actually lays when it is installed.  Have you guys just been ignoring the difference? Often a person wants  to know how deep they need to dig when installing so they will measure off the bottom of pipe profile to EG. Anyone have any problems with this in practice. Better yet does anyone have a solution to create a dynamic offset profile?

Well I assure you it is not defiantly but perhaps definitely.  Anyway, where I come from when we are down in the trenches we normally use the "TIMEX" method.   The "Rolex" method must be used elsewhere.  We set grades with conventional leveling instruments that measure elevations vertically.
