Civil 3D® Point Data – User Defined Property Classification

Hello everyone, I have another tip for you. Have you ever wanted to add additional data to your civil point data?

Well, with Civil 3D® User Defined Property Classification you can add that data. This gives the user the ability to view additional data for the point location.

To add User Defined Property Classification, go to the settings tab and select User Defined Property Classification, right click new > to add the name of the class. That will add the class to the tree.

Next, add the property field type for the data type being attached. String, double, station …… add as many fields as required for your data.

Next, add a point group to accept the User Defined Property Classification data. While in the point group dialog select the summary tab, and in the general section, select the Classification drop-down and select the new class name.

Next, create import/export format that includes fields that correspond to the data being imported. Use the new import format to insert points in the drawing. After the points are inserted select one of the points and right click and select properties. You should see the User Defined Property Classification fields at the bottom of the property dialog.

With these fields attached you can add this data to Civil 3D® point tables. Note that with the use of point tables the data attached is dynamic and the data exposed in the property dialog is also dynamic edit.

Hopefully this additionally displayed data helps while you’re working on your design and in production.

Thanks for reading, and I hope this helps!



On with another quick-tip today. This is a command that it took me a while to realise how useful it truly is – SELECTSIMILAR.

One of the most fundamental tasks in AutoCAD® is creating your selection to manipulate. There are many ways to select, and generally you’ll end up windowing entities on screen.

But, you must remember that it is not the only way – sometimes you’ll have an idea for what you want to achieve, and often another command isn’t only faster, it’s more semantically correct to use, and therefore less prone to errors that you might make doing it another way.

So in cases where you have objects that are in some way similar (i.e, same layer, type, colour etc), go crazy with the SELECTSIMILAR command. You’ll grow to love it – trust me. There are many different object properties you can use to define what “similar” is. Typing “SE” for settings after invoking the SELECTSIMILAR command brings up this dialog box:

SelectSimilar Dialog Box

It is worth noting that if you’re using one of the verticals of AutoCAD® such as Civil 3D®, there are actually variants of the SELECTSIMILAR command. For example, right clicking an object and picking the “Select Similar” object actually invokes a different command, namely the AECSELECTSIMILAR command. This variant is not governed by the same settings dialog, and does not appear to have the same level of control – for this reason I personally prefer the good old fashioned SELECTSIMILAR command.

That’s all for today,

The LAYDEL Command

Firstly, many thanks to Mark Pettitt and John Coon for their first posts on A great start to something very positive and beneficial for all.

Secondly, I have a quick-tip for today. I literally used it under 5 minutes ago and it was so useful that I just had to write a post on it immediately.

The LAYDEL command. Using this command you can literally scoop spoonfuls of additional productivity into your work (see what I did there?? hehe).

This command identifies and deletes all entities on a layer, and removes the layer. On it’s own this might not seem very special, but read on… Consider you’re working with LOADS of data… normally you’d perhaps isolate the layer, select all the entities, and delete right? Well, as discussed previously in my guide to what causes AutoCAD® to freeze or crash, this is one of them. Selecting a large number of entities invites AutoCAD® to start “preparing” things, and it is a great way to crash AutoCAD.

Because LAYDEL is a built in AutoCAD® command, it is much MUCH faster than any way of doing the same thing. It’s lightning fast – and that makes me love it ! 😀

That’s all for now,


P.S. I’m going to have to do a top 10 coolest-named AutoCAD® commands… send me your nominations if you like!

Missing Setting Tab

Hello, this is my first post on  My name is John Coon.  I’ve been using AutoCAD® and AutoCAD® civil add-on products for some 25 years.   The firm I work for, Hoyle, Tanner & Associates, Inc.  works on airport construction projects along the eastern United States. I’ve worked mainly on aviation design projects for the past 20 years. I hope to post general Civil 3D® tips.

Last week while using civil 3D 2011 I somehow lost my Settings tab. Well, what I found out was that using the preview somehow makes the setting tab disappear. I’m not sure why, but to get the settings tab back type  “SETTING”. This should restore the missing settings tab.

I’ve tried to reproduce the same on my 2012 install but it doesn’t seem to happen.
