Curb Profiles - Using Reference Alignment Function On Alignments

Sometimes on corridor / road projects you will be provided with the curb details as curb profiles. Those curb profiles will have elevations that are sometimes / often defined using Stationing from the main road alignment.

You can create the curb using a Linestring and then create points using the Station Offset Elevation or Create Dependent Points command and then elevate the linestring from the points using the Elevate Lines command in Point Mode.

If you want to create the curb line as an alignment, you can define the horizontal alignment using CAD tools and then make an alignment out of it, but how do you then assign elevations to the vertical profile when the stations are referenced from the main line of the road?

In an alignment, if you look at it’s properties, you will find that there is the option to select a Reference Alignment. When you select a Reference Alignment, the stationing for the Alignment is now being derived from the Reference Alignment. Once that has been implemented, then you can create a Vertical Alignment and simply type in the Station and Elevation values that you have been given for the curb profile line.

You can add the main alignment and the curb profile alignment to a surface model without issue to build your final surface model.

Note: I am not sure on how SCS900 / Siteworks / GCS900 / Earthworks will handle a surface that is made in this way, you may want to create a TTM output for the final surface when you have completed it rather than send the surface out as a VCL file.
