Some folks will unquestionably wait for an upcoming Autodesk Civil 3D 2025.1 Update before they upgrade to the 2025 release of Civil 3D. That’s a historical habit thing, do’n ja know. Before and during the recent July 4th week, Autodesk released the Civil 3D 2025.02 Update, a couple of significant Civil 3D Tools, and those sometimes vital Toolbox Extensions for Civil 3D.

Many of us out here in Civil 3D Land employ standard workflows that at times do depend on one or more of…

The Civil 3D 2025 Goodies

These useful tools all came out a bit earlier this year probably because Autodesk University is earlier this year as well  – AU 2024 is Oct 15-16, 2024, in San Diego, CA.

Did you know that there are now new AU sessions being added online all year long?
We can even sign up for the live session presentations. Say what?
Honestly, maybe I missed that, lost track, or forgot. Dooh.
 Register for AU 2024.

Before we get into all of the recently released Civil 3D 2025 goodies detail, let’s also note that there’s a new July Autodesk Desktop Connector (ADC) release available.
See the Autodesk Desktop Connector News post.
Am I the only one that’s a little annoyed the ADC updates don’t appear in Autodesk Access?
Oh bother.

We are careful to check and post the new ADC releases as they happen on our News page.

Be aware that in early July Autodesk announced a different ADC July version. However, it seems Autodesk never officially released that build into the wild via the public download links.
Just sayin’.

To repeat my Reference Explorer rant - Even if we don’t want to employ the Autodesk Clouds to host our Civil 3D projects, the ADC’s Reference Explorer is a very handy local tool to help us check and fix Civil 3D project integrity and all the many references in our project drawings.
See the Civil 3D Reference Replacement and Tools post and videos.
Don’t use Civil 3D without it.

Perhaps we don’t really have to hold our breath all that long for the upcoming Update 2 to the Autodesk DWG Migration for Docs (DMD) tool. The latest and greatest DMD will also help us check and update Civil 3D projects on our local networks.
Maybe we can hold our breath long enough for a new DMD?
Meanwhile see the older version DWG Migration for Docs post and videos.

Here are the latest Civil 3D 2025 goodies…

Civil 3D 2025.02 Update

Officially, the Civil 3D 2025.0.2 Update addresses an important issue where Civil 3D stopped unexpectedly when exporting to AutoCAD or exploding a surface that used a style with points displayed. Ouch.
See the Civil 3D 2025.0.2 Update News post.

Unofficially, we can probably also bet the included Civil 3D 2025.0.1 Update and the Civil 3D 2025.02 Update include some other integration code for the Civil 3D Extensions and Civil 3D Tools that were released a couple of days afterwords.

GENIO Import-Export Extension 2025

If we must work with Bently apps the GENIO Import-Export Extension streamlines the migration of data from Bentley MXROAD software to Autodesk Civil 3D software. It also enables customers to use Autodesk Civil 3D on projects that require Bentley MXROAD format deliverables and/or the use GENIO or binary 'modelfile' format as data sources.

The GENIO Extension is a Civil 3D Toolbox tool.
See the GENIO Import-Export Extension News post.

PPK Survey Extension 2025

Survey folks all recognize that the PPK Survey Extension for Autodesk Civil 3D provides an interface for importing GPS data (in RINEX format) for analysis, reporting, and converting it to coordinate geometry points in an Autodesk Civil 3D drawing.

The PPK Survey Extension is a Civil 3D Toolbox tool.
See the PPK Survey Extension 2025 News post.
See the PPK Survey Extension in the Civil 3D 2025 Help.

After installation Civil 3D users can access the PPK Survey Extension for Civil 3D commands via the Civil 3D Toolbox under:
GNSS Data Processing>>Post Process Kinematic Survey

Autodesk Coordinates Transformation Tool 2025

The Coordinates Transformation Tool provides vital tools for civil engineering projects where a user may need to transform Autodesk Civil 3D objects from one coordinate system to another within the drawing environment.

The Transform Tool allows for horizontal transform, vertical datum transform, and vertical units transform from US Survey Foot to International Foot and from International Foot to US Survey Foot.

The Transform Tool also provides a comprehensive report of what was transformed along with the before and after coordinates to ensure the accuracy of the transformation results. Hoorah!
See the Coordinates Transformation Tools in the Civil 3D 2025 Help.

Nope. The Transform Tool is not the same thing as the new AutoCAD 2025 coordinate systems setup interface that allows for vertical datums in the coordinate systems setup.
See the Coordinates Transformation Tool 2025 News post.

Geotechnical Modeler Extension 2025

The Autodesk version of Holes. Pun intended. Eheh.
Holes is probably not anyone’s favorite Sigourney Weaver flick.

The Geotechnical Modeler Extension provides a suite of tools to visualize, process, analyze and export geotechnical data directly within the Civil 3D environment for use in a variety of civil engineering design projects.

Geotechnical for Autodesk Civil 3D 2025 consists of the following features and updates:

  • Import borehole data from industry-standard file formats
  • Manage subsurface information in SQL database
  • Create surfaces from borehole data
  • Generate customized subsurface profiles using Civil 3D alignments
  • Visualize boreholes in 2D plan and 3D stick logs view
  • Export geotechnical data in a 3D format for conceptual design and visualization applications

See the Geotechnical Modeler Extension 2025 News post.
See the Geotechnical Modeler Extension in the Civil 3D 2025 Help.

A Better Toolbox?

It remains to be seen if these newer .Net 8 versions of the classic Civil 3D Tools and Extensions run a bit brisker than the older ones.
Probably would be my best guess.
What do I know?
