This is the 4th and last post in the series on how to utilize subassemblies to fill in the gap on divided roadways. Here the Median Flush with Barrier from the Tool Palettes Medians tab will be used:
Some of the median subassemblies work a bit different than the ones shown in the previous posts or how you might be used to working building Civil 3D Assemblies. Usually, we will see a Left and Right group, in this case, there will be a single grouping called “Centered”.
Subassembly: Median Raised with Crown
Directly from the HELP file:
This subassembly inserts links for a constant-slope raised median between two points.
This subassembly inserts surfaces to define a flush median with an optional New Jersey Barrier.
The pavement structure follows the standards described in “Pavement Structure of Paved Sections" in the Autodesk Civil 3D Help.
The attachment point is at the center of median on the finish grade surface. This component inserts to the left and right side simultaneously.
How to put it all together: Assembly
Again, a bit different from the workflow that we might be used to in building Assemblies. There will NOT be a LEFT and/or RIGHT side, but starting from the center and building on to it.
The Median will be added to the main Assembly attachment point, and any subassembly will appear attached to it as a single “Centered” list.
If everything is right, our corridor will be built correctly as shown in the cross-sections below:
Here is a closer look of the Median area.
These types of centered subassemblies are easy to use. I hope you have enjoyed all the information in the series.
