How to Create Surface from Text in Civil3D (Also Assign Elevations to Text!)

Assign Elevation to Text Automatically Civil 3d

Often times we receive exported files from other surveyors that we need to use in our drawings. At this time, it is great that AutoCAD Civil 3D gives us the opportunity to Create a Surface from Text Objects. To illustrate better the task. We will look at an example where we have received a drawing … Read more

How To Raise or Lower Multiple Feature Lines in Civil 3D

Raise Lower Feature Lines Civil 3D

It is quite a common task, to raise or lower the elevations of all vertexes of a feature line in a drawing. The reasons can be anything, from using the wrong benchmark to revisions by the client. No matter the reasons, it is great to have the opportunity to automatically raise or lower vertexes by … Read more

Convert Anonymous Blocks *U### to Normal AutoCAD Blocks

*U### Block to normal AutoCAD Block

Today’s issue we are going to deal with will be converting anonymous block objects in normal AutoCAD Blocks. *U### blocks? Usually, anonymous blocks are really annoying and hard to work with. They have strange names for example block with * in front of a random name. The different types of names mean that things though … Read more

At the beginning of 2018 at work, we moved to AutoCAD Civil 3d 2018, there is some cool new stuff but we faced some really annoying issues. Issues Label and Arc Grip Issue The first problem we faced were the grips of Spot Elevation Surface Labels. Whenever we try to move the labels using the grips, the … Read more

AutoCAD Points or Civil 3D COGO Points (What’s new?)

Points are essential objects for Engineers, Land Surveyors and drafters as they represent the coordinates of real objects into the CAD world. AutoCAD gives us this point functionality with its Point objects, however, if we use Civil 3d we will be working with Coordinate Geometry (COGOpoints. Cogo points are very different than AutoCAD Point nodes, let’s see why!

AutoCAD point

To extract information from point objects in the file, we can use DataExtraction .

To modify look of our points we can enter in point style menu by typing DDPTYPE at the command line.

A window will pop up called Point Style, there we can find AutoCAD’s point styles suggestions. We can also change the point size, the two options for changing the size are – Set Size Relative to Screen and Set Size in Absolute Units. The names are pretty self-explanatory – if we need points to show up in our drawing with specific size we can use the Absolute units’ option. If we are not sure about the scale of the drawing we can use the Relative size.

If we need to place multiple points along an object we can use Measure or Divide commands – This is a really easy way to find coordinates of an object.

The main problem with AutoCAD Point objects is that we can’t add any additional information to them. I’ve seen countless times AutoCAD point and Text object right next to it. Yes, this may do the trick, but we don’t want to waste much time on typing some stuff that we can’t extract later on.
Yes we can create a block with attributes that will have some extractable information, however, if we can use Civil 3D and Coordinate Geometry (COGOpoints we should definitely do so, here is why:

Coordinate Geometry (COGOpoints

Cogo Point is a more advanced point – it a part of AutoCAD Civil 3D package. Every Cogo Point has its own unique number and name. We define points with Description that can contain a wide variety of information.

Cogo Points can be created in different ways:

Manual points or by reference – interpolate, intersect, measure, divide and so in. To do that we have to click on Create Points command located on Home tab, then choose one of following:

Create Point – Miscellaneous, Create Point – Intersections, Create Point – Slope, Create Point – Interpolate

We can also create points from Civil 3D objects – like Alignments, Surfaces, and Corridors. This can be done again by clicking on Create points command and expand one of the following menus:

Create Point -Alignment, Create Point -Surface, Create COGO Point from Corridor

There is an option to convert AutoCAD or Land Desktop points to Cogo Points.

We can arrange our Cogo Points in Point groups so they will be easier to manipulate.


Before creating our Cogo points we can pre-set a lot of settings by hitting on Point Creation Tools. A window called Create Points will pop up. We will see Default Layer, Point Creation, Deault Styles, Default Name format and Point Identity tabs that can be expanded.

  • Default Layer tab is for setting a layer for our new points.
  • Under Points Creation, we can set position properties of the points along with default elevations and descriptions.
  • Default Styles is used for choosing a Point and Label styles
  • Under Default Name Format we set the counter style and incremet for our Points and Point groups
  • Point Identity tab is mostly used for setting the next Point number

Cogo Point creation tools


In conclusion, i’d like to say that it is really important to understand Coordinate Geometry (COGO) points and start using them because they give us so much more options. They are simple and easy to Create and Use.  The only downside is that they are “big” and heavy objects and if we have lots of them in our drawings AutoCAD Civil 3d can start working slower even on good working stations, so be wise when using them.
