Civil 3D 2017 What’s New: Feature Lines as Corridor Baseline

May 16, 2016 By Leo Lavayen Leave a comment

Feature Lines have always carried the X,Y (like an Alignment) and the Z (similar to a Profile). I'm glad to finally see this AWESOME update in Civil 3D 2017, giving users the ability to create a Corridor from a Feature Line.

Points from Alignment using Civil 3D Surface Elevations (bilingual)

June 16, 2015 By Leo Lavayen Leave a comment

I recently was involved in two seperate support cases for Civil 3D, where the software users asked for assistance with alignment using surface elevations. I decided to create this blog post as a quick reference on this design issue, as well as provide the same information in Spanish.

Casual Corridors: Removing the Bow Tie

January 07, 2015 By Leo Lavayen Leave a comment

When the corners get tight with sharp bends, corridor sections will begin to cross one another. This issue is known as a “Bow Tie."


Once a Bow Tie is created, the corridor will not behave as expected and corridor commands will experience issues too.

You can correct this issue a few different ways:

  1. Modify frequency and sampling settings.
  2. Add curve to the bend (PI).
  3. Use a custom assembly in region along with gradings.
