Profile Editing Enhancements in Civil 3D 2015

We at Ideate are looking through the new features in the latest release of Autodesk software. In this post, I am going to discuss the new profile editing enhancements in Civil 3D 2015.

Profile Extending and Adding Entities Before Previously Drawn Entities

Civil 3D has a made a few enhancements to its profile editing options. The first is the extend entity tool which shows up on the profile layout tools toolbar. 

The Extend Entity tool on the profile layout toolbar
This tool extends an entity to the end or beginning of a profile. This does not mean the end or beginning of the horizontal alignment. The profile will be extended to the nearest major station, as can be seen in the following image.

Another important addition is the ability to add entities before previously-drawn entities. This is particularly useful if additional entities have been added at the beginning of your horizontal alignment.

Free Curve Editing

Multiple additions have been made to the free curve editing, with the most notable being the ability to add a free circular curve by selecting entities that the curve will be connected to. Refer to the following image to see where this is on the toolbar. This option allows you to create the curve by selecting the two entities the curve will be between, and then determining the curve geometry by selecting a pass-through point, or indicating a radius or length.

The parabolic curves can also be created using a pass-through point. This is new to this release. To ensure these pass-through point curves are compatible with previous versions of the software, you can convert the curve to be pvi based. This option is shown in the following image.

In short, the new profile editing features include the ability:
  • To create entities before previously drawn entities.
  • To extend entities to the extents of the profile (nearest major station).
  • To create circular free curves by selecting entities before and after the curve.
  • To create curves by a pass-through point.
  • To convert the pass-through point curves to pvi based curves for backward compatibility.
