C3D Survey How to Create a 3D parallel Offset Lines

[david.wylie689041]

I'm puzzled, I have the crews creating C3D figures using the Figure Coding quite successfully and would like to incorporate parallel offset lines. As an example, Survey the gutter of a curb and create the back of curb as an offset line. The problem is that combining the H (horizontal offset) and V (vertical offset), as in 1001 CG B H0.15 V0.15, (metric) gives me two seperate parallel lines, one horizontally offset, the other vertically offset from the surveyed line, in this case, CG gutter. Is there a way to create a single offset line horizontally and vertically offset from the surveyed line? Any suggestions and pointers would be appreciated.

Welcome to AUGI.

I don't recall if this works on Survey Figures, and I don't have any at the moment, but give the OFFSETFEATURE Command a try.

I mostly use this Command to quickly offset a graded Feature Line (Rear lot lines, as example), at a specific slope (1:4, 1:6, etc.) well beyond the elevation of an existing surface, as part of my proposed Surface, only to subsequently run the MINIMUMDISTBETWEENSURFACES Command to get my daylight line.

[Edit] - You could always Raise/Lower a Horizontal offset as well.

In any event, HTH

Thanks BlackBox I'll give both methods a try. I was hoping there was some method that the field crew could incorporate into their field work pick up procedures that way when there is a change in the offset requirements, for example when the curb they are surveying changes from a standard curb to the curb cut, they can simply change the coding, but I guess you can't have everything. Have a good week.

thanks

Sorry I couldn't be of more help - in full disclosure, I'm a Civil designer, not a surveyor, so someone more adept at survey side may know of a better solution.

Your code appears correctly coded. I'm not sure why it is not working as specified in the help for Special Codes.

Have you reported it as a bug?

I see the benefit in using these offsets, however, the real world is seldom constantly at those specified offsets. Therefore, we do not code with them.

Sorry I wasn't much help, though.
