Just wondering if there's an easy way to project the chainage from a centerline alignment to an offset alignment. A contractor has asked for this as it helps them with construction staking. I understand that mathematically the chainage of an offset alignment will change due to arc radii being different and this will have a compound effect as you go further along the alignment, hence the reason why just applying the chainage regularly to the offset alignment won't work.
Is there a way to develop/report/export this quickly/easily in ORD?
Would the Station Offset Report get that. It seems to be what you are looking for. The station and off set from one alignment relative to an offset alignment. The report below show the Station and off set of my "Offset Agligment" at the 25 FT station interval along my "Mainline" alignment. You can switch it up and do several variations of this with the reports.

Hi Mike, yeah, this looks like the closest available solution. If there's a way that multiple offset alignments could be added (I tried adding multiple offset alignments (ex. a left offset alignment and a right offset alignment) though only one offset alignment seems to show up in the report) and also if the xy coordinates of the alignments at the stations listed could be displayed that would be optimal.
I am able to select more than one offset geometry and it reports on both. There are several types of reports depending on what you need. I used the Station Offset, there is a Station Base report type, then within the report's browser there are StationOffset and StationBase Coordinate reports depending on what you need. It is possible to create custom report combining these but typically cutting and pasting to a spread sheet works well.
Thanks, Mike -I will explore these options.
The reports use XML data and reformat it to an HTML document. Often, the XML document contains more information than the report uses. When that is the case, it is possible to modify the XSL file to add columns or rows to report on the supplied, but unused data. And sometimes, there are other reports that do use the data which at the very least can be used as a guide to your modifications.
While it is not rocket science, it is a learning experience. Here are some starting tips:
