AutoCAD Civil 3D Segment Label Error Fixed

I was reliving problems that we had with Parcel Labels in AutoCAD Civil 3D, as far back as 4 years ago. The problem is that all the curve geometry is labeled correctly, except the chord length. Rather than re-explain the entire process, I’ll simply say that various methods were used to evaluate the curve, and only the chord length in the label is wonky. Here is the article:

I thought it was a software problem, however I think I have it figured out.

It is a Slope Issue

I decided that there must be something in that curve geometry that is causing the problem. I decided to check the elevations along the parcel (which many hold as a flat value). Sure enough, the curve had a slope.

A quick change of everything back to 0, and the labels behave.

Notice the chord value changes, but nothing else does.

Clearly there is a problem in how the chord is calculated in the label, vs. the Parcel Vista and the like. Keep this in mind the next time your labels don’t reflect compatible data. If this helped anyone, please leave us a comment.


Civil 3D | Remove Specific Station Labels

Autodesk AutoCAD Civil 3D End Station LabelIf you’ve been fighting the beginning or end station labels on Autodesk Civil 3D Alignments, here’s the fix. Sadly, the answer has been around for a long time.

Civil 3D End Station Label

We often manually add our end station label, customized how we like, and in the case of some plans, the end station is denoted in a separate table. In all cases, the end station is automatically generated on the Civil 3D alignment.

  • It is usually useless, and is traded out for a more useful end station geometry label
  • It is ALWAYS in conflict with something

You can select the label, but it is a function of the entire label set, and highlights the whole set accordingly. If you delete it, you will delete the entire set.

There is a fix that is so easy, you will laugh until you cry from the frustration of it all


That’s right. Hold the CTRL key and pick all the specific labels your hear desires. Release the CTRL key, and push the DELETE key. It is that simple. The labels will be gone.

Use the Station Label Control Dialog

AUGI member Anthony Rhodes answered such a question in January of 2009. He noted the how the Station Label control dialog is supposed to be used, and the fact that it does work. Edit the alignment labels. Enter in the desire stations to start and end the labels.

In this example, any stations after 10+00 will be removed.

While I don’t have a copy of the awesome book “Mastering Civil 3D” handy, I’ll bet money that this information is in there.


The answer for this has been around for a long time. So long that I wanted to credit those who pointed it out.

Autodesk Civil 3D | Pressure Pipes Network Information

Civil 3D 2013 brought us pressure pipes, and a whole load of new configuration issues with additional catalogues. I had a friend who was missing some data, and I started digging about. As many of you recall, I spent a great deal of time trying to decode the mysteries behind the Civil 3D Parts Builder, and after that experience I vowed to never dig back into that part of the software again.

Here’s a YouTube video from my friends in Arizona. Ron Couillard discusses some new features and updates in 2014 and demonstrates some of the process. If you are going to Autodesk University, make sure you attend his classes; they are always good.

AutoCAD | 2014 Startup Lisp and Autodesk New Security

I noticed that after a recent update to AutoCAD 2013, my acad2013doc.lsp would not load on its own. I thought it was just my machine, but soon found that others machine’s responded the same after the update. Now I have a new Lenovo platform (more on that later), I have a nice clean install of Product Design Suite 2014 and Infrastructure Design Suite 2014.

I expected to leave behind the quirky attitude 2013 has taken on, but this was not the case. My acad2014doc.lsp would not load on its own. I could however manually load it, but that kind of kills the intent. You see our acad lisp file auto-loads a hand full of variables and conversion base apps that are then fed to a small list of extremely effective lisp routines. Without the preload, the remaining apps are dead meat.

Here’s what I found out about the new installations of AutoCAD. There is a new security protocol that has been implemented, and as a result, some additional paths and variables need to be understood. The that I will discuss today is ‘Trusted Locations’.

Appload start-up suite

The Appload start-up suite makes preloading easy so that apps are ready to go once AutoCAD loads any drawing. Sticking the Acad2014doc.lsp there did cause the system to load the file, but unfortunately the routines that the startup suite called for are not in a ‘trusted’ location, and as a result users are prompted to load each and every subroutine that is being loaded from non’-trusted file paths.

AutoCAD 2014 appload startup

Trusted Locations

AutoCAD now restricts applications being loaded unless they are entered into the list of AutoCAD’s trusted paths. That’s right, the fact that you entered the appropriate search paths that you wanted in the support file search path was not good enough, you now have to tell AutoCAD that you really – REALLY want to load the support files…. because I have so many people trying to hack my AutoCAD setup????

AutoCAD 2014 Trusted Locations Configuration

If you navigate to the files tab in the AutoCAD configuration dialog (‘CONFIG’ on the command line), you will find a new entry structure titled ‘Trusted Locations’. As you can see, the default roaming account’s AutoCAD support path is already loaded there which is why the Acad2014doc.lsp loaded after install, but not after being re-routed to the custom file set.

In any case, once the custom path was entered, the respective files (including sub-folders) auto-load and all is well again.

Autodesk Security Discussion

Here’s a link to a discussion that got me thinking about the topic that might help some folks.

Civil 3D | Site Parcel Style

Here’s a quick tip to help Civil 3D CAD users understand how to change the outer edge of their Site Parcel limits. Sometimes the outer edge just won’t seem to change, no matter how we style the Parcels. In this case, the development is phased, and I have changed one phase to be focused (here, the color blue), and the remainder to be a standard weight (here, black).

One issue that arises is that the Site can have a style all it’s own:

  • Benefit – Outlines the limits of the site by parcel, making it easy to delineate
  • Drawback – It can behave opposite of what you may desire, depending on what document type you are publishing.

In this example, I need a specific phase focused. I changed the Phase’s individual Parcel style to be focused, and the remaining parcels to be a standard parcel type. However the entire development continues to display focused.

Autodesk AutoCAD Civil 3D 2013 How to Change Site Parcel Style

Edit the Site’s Parcel Style

Here’s how. Navigate to the Site Parcel Style selection:

Prospector-> Sites-> [Your site name] –> Parcels

Autodesk AutoCAD Civil 3D 2013 Site Parcel Properties

Pick properties from the context menu. At the top, change the Site Parcel Style to be the one desired. In my case, from focused to standard parcel. When applied, the outer edge of the parcel follows the new display style.

It’s a Good Thing

You can use this to your benefit as this capability has a lot of potential, including shading styles that can be switched off and on by layer as well. Give it a try in you scenarios.
