AutoCAD Data Extraction: Take Your Drawing to the Next Level

Many people are still using it that way, at least in my country. I am not sure how people are using AutoCAD in your region today, but I believe many people are still using it that way. Many AutoCAD users forget that Please Login or Register to see the link. has added many new features that can increase their productivity.

In this post, I would like to cover my favorite productivity feature: data extraction. This automatic process can generate your drawing information in a table. Let us see how we can implement it in our design process.

What is data extraction?

Snipped from help file:

“You use the Data Extraction wizard to choose the data source (drawings) to extract property data from selected objects. You can output the data to a table or external file.”

Data extraction allows you to get almost any (if not all) drawing elements’ properties from your drawing. You can then report the properties in a table within your drawing or as external file.

This example is using data extraction to generate set out points for land surveyor. As you can see, it generates the gully ID and three set out coordinates.

I am not going to write a tutorial how to use data extraction. Let us see how we can use this feature to take our drawings to the next level. The drawings are not just about showing lines and annotations. It also generates information! A little drawing management can actually boost your productivity and take your drawings to the next level. It is not just about how the drawings would look like when we plot it.

Several Data Extraction practice samples

AutoCAD is used in many industries, so data extraction implementation can be different for each industry. Let us see several usage of data extraction that I can found.

Laser Cutting Data

Data extraction can Please Login or Register to see the link.. These are basic information that data extraction can generate. I found someone asking how to get these data for laser cutting. I am not sure how to use the data, but at least he gets what he is looking for.

Benchmark and Set Out Points

We can generate points coordinate from AutoCAD objects such as circles and points. However, if we manage our objects as blocks, we can get more advantages. It is not only easier to filter the objects; a simple benchmark point block can generate the block insertion point and the benchmark points ID. The ID is managed by block attributes.

Unlike basic AutoCAD objects, we can also generate multiple points coordinate within one block. A sample for this purpose Please Login or Register to see the link.. This is very useful for land surveyor.

Holes Table

Holes table is common data you would like to have in manufacturing industry. This is very similar with benchmark and set out points for land surveyor. Engineers would like to have the holes coordinates and holes sizes. You can do it easily by data extraction!

Schedule

AutoCAD is not as smart as AutoCAD Architecture or Revit. Nevertheless, you still can make use the data in your drawings. For example Please Login or Register to see the link.!

Again, the key is defining your objects properly. Dynamic blocks can be very useful. Dynamic block parameters can be reported by data extraction too. Therefore, you can report number of doors by their width, for example. You can also add more information such as door manufacturer, fire ratings, etc. Just like in Please Login or Register to see the link. or Please Login or Register to see the link.! But sure, we are working in 2D here.

What is Your Favorite Practice of Data Extraction?

So are you already using data extraction? Do you have any other samples how we can utilize this feature in other industries? Please share it here, we would like to hear from you!
