Apply Transitions to Virtually any Civil 3D Subassembly!

Quite often, a proposed corridor design will require subassemblies to transition or change shape as they progress along an alignment.  Typically, these transitions are controlled using a horizontal, vertical, or surface target so long as the subassembly part supports it.  Not all of them do.

In today’s installment we’ll look at a way to assign transitions to virtually any subassembly part, even if it doesn’t support targeting.  We’ll do that by creating a “numeric control line” to calculate and apply the transitions for us!

If you are interested, I’ve created a quick video below that walks through everything…

Sharing Properties Between Civil 3D Subassemblies using Output Parameters

If multiple parts in a Civil 3D Assembly require the same dimension or slope, it may be possible to share their common properties.  By sharing properties, future design changes are more efficient because one subassembly part can be used to drive the properties of several others.  In today’s installment we’ll learn about a concept called Output Parameters.

Output parameters represent dimensional values that are baked into many of the “out of the box” Civil 3D subassemblies.  Specifically, output parameters are values that a subassembly part can pass to other subassembly parts.  (To view the available output parameters for any subassembly, Rt-Click on its icon in the Tool Palette and select Help from the menu.)

Using output parameters, dimensional properties can be applied to a group of subassemblies, making it much easier to modify a proposed design!  If you are interested, I’ve created a quick video below that demonstrates some possible workflows.
