The NEW Feature Line

[#1]

If you haven't installed the Civil 3D 2026.2 update, you need to!

There are a ton of new features and improvements with this update. In this blog, we are just going to focus on the new feature line.

Below is a list of the enhancements that have been brought to the new feature line...

• Performance Improvements:
  • When editing elevations.
  • When selecting and querying in the feature line properties palette.
  • When offsetting siteless feature lines to maintain their independent non-site status.
  • When editing siteless feature lines.
  • When adding a Point of Intersection (PI) to a feature line's arc segment, maintain the original radius of both arc segments.
  • When importing and exporting to LandXML.
• Added a notification for clear feedback when converting a feature line segment from a straight line to an arc.
• Added the ability to edit the elevation of a PI and elevation point when hovering over the feature line PI or elevation point.
• Enabled conversion between feature line segments and arcs, allowing the extension of feature lines at either endpoint through both the ribbon and in-canvas interface. 

We are going to focus specifically on the last two listed above. Below, you can see a regular AutoCAD polyline with it's multi-functional grips shown...

What is a multi-functional grip? It's a grip that gives you certain functionality by "hovering" over the grip and selecting an option.

These are great! It makes certain tasks so much easier and quicker. Now, I'm going to convert this polyline to a feature line. Look at the grips!...

They are now identical to a polyline! However, the multi-functional grips have different options aside from an AutoCAD polyline...

For the middle grips, you get the options to Convert to Line/Arc, Insert PI, or Insert Elevation Point. Hovering over an end grip gives you even more options...

You can now Stretch, Insert PI, Delete PI, Insert Elevation Point, or Edit Elevation. This makes it much quicker to alter/edit a feature line without having to use the ribbon. 

I hope you enjoyed this quick blog and that it will aide you in making edits faster to improve your performance in production.
