People often ask me how we build corridor models with either a single template or very few templates. The secret to success is getting your linework for the corridor broken up as you need it to aid the handling of offsets (widths) and break out areas (driveways etc.) and also tabulating the variations in cross slopes and or widths in a spreadsheet and then using those pieces of information using instruction tables for Width, Slope, Elevation etc.
We typically recommend that you go through the plans and tabulate everything you can about the corridor before you start trying to build it. If you tabulate all of the cross slope and width changes and you work through the provided CAD data to extract the lines that you need for lanes, shoulders, median islands etc. and you organize your data well, then building corridor models can be a pretty quick and easy process.
In the video below we show some of the secrets to using Tables successfully in corridor models. We show how to enter tables manually, how to copy and paste tables from a spreadsheet, and how to use 2D lines in Tables and how to use the ? (undefined) to stop and start elements at e.g. Driveways etc.
These are the absolute fundamentals of building corridors successfully, learning these methods will save you hours of work, will eliminate dozens of instructions and will increase the quality of your output models.
