Civil 3D Corridor Frequencies
Jeewana Meegahage shows and explains the details of Civil 3D Corridor Frequency methods and mechanics.
Of course this takes a bit, but the effort is worth the time to produce better Civil 3D Corridors faster.
Visit the JeewC3D YouTube page.
The video delivers a great walkthrough demo to help us better understand Corridor Frequencies.
The Excel trick to add multiple special Station Frequencies to a Region is covered near the end. Hoorah.
This trick also works from a line by line text file. A spreadsheet makes it easy if we need to calculate them.
