Is it possible to get an option to quickly offset a surface perpendicular. For example a ditch shape.
It seems as the newest version of TBC will now create 3D linestrings when your corridor is created. For now, it could be one way of creating what you need which may take a bit longer to use those linestring and do a delta offset. Which I cannot say if TBC will allow you to copy those lines and it not be dependent of the corridor.
This has been ask for some time now and I have come across a way. I’m sure someone will chime in.
You cannot copy them. You have to export them out as a dwg then reimport.
bummer. just like the side slope command. BUT, the side slope has the explode function.
Trimble access does this on the Data collector where I can offset the surface perp and get deltas to that surface. I’m not sure why TBC can’t have this function.
Have you tried the RPS Offset Surface Command? You can offset an entire surface or an area in a surface. It’s located in the RPS Modeling ribbon tab. Here’s a link to the command video.
It offsets the surface vertically and not perpendicular.
There is an option for this in the MSI Library under the Site Improvement but I am not sure if that does what you need??
You could also offset the main surface and use sideslope or our slope designer after the fact to find the intersect… Tough to say for certain without seeing the data and what you are trying to achieve, but I am sure we could help you work something out.
We would like the offset surface to have a perpendicular option as this berm/ditch has 5-6 layers on top and all need perpendicular offsets.

I would typically recommend that you use the RPS Offset Slope or Slope Slope command for this - that will offset the Top and Toe strings for Ditch left and right perp to the slope between the strings - you can then use those strings to create the subgrade model for the ditch.
It is easier and faster and more reliable to do this from strings than it is to do it from a TIN model because of all the triangle issues that occur when you try offsetting a TIN perpendicularly.
Let me know if you need help with this
