An AutoCAD Version Converter is a tool or feature used to change an AutoCAD drawing from one DWG file format to another version.
AutoCAD uses the DWG format as its native drawing file format. However, the DWG format has changed across different AutoCAD releases. Consequently, a drawing created in a newer release may not always open directly in an older release.
For instance, Autodesk explains that newer AutoCAD products can generally open and edit older DWG formats, whereas older AutoCAD versions cannot open newer DWG formats.
Therefore, when you need to send a drawing to somebody using an older version of AutoCAD, you may need to convert the file first.
An AutoCAD Version Converter may refer to:
- AutoCAD’s Save As function
- The DWG Convert feature
- The DWGCONVERT command
- Autodesk DWG TrueView
- Other compatible third-party DWG conversion software
However, when working with important professional drawings, it is advisable to use Autodesk-supported tools whenever possible.
Understanding AutoCAD DWG File Versions
Before converting a drawing, it is important to understand that AutoCAD version and DWG file version are related but not always identical.
For example, Autodesk’s current compatibility information shows that AutoCAD releases from 2018 through 2027 use the AutoCAD 2018 DWG format as their native format. Similarly, AutoCAD 2013–2017 use the AutoCAD 2013 format, while AutoCAD 2010–2012 use the AutoCAD 2010 format.
A simple overview is:
AutoCAD Releases | Native DWG Format |
| AutoCAD 2027–2018 | AutoCAD 2018 |
| AutoCAD 2017–2013 | AutoCAD 2013 |
| AutoCAD 2012–2010 | AutoCAD 2010 |
| AutoCAD 2009–2007 | AutoCAD 2007 |
| AutoCAD 2006–2004 | AutoCAD 2004 |
| AutoCAD 2002–2000 | AutoCAD 2000 |
| AutoCAD R14 | AutoCAD R14 |
| AutoCAD R12 | AutoCAD R12 DXF |
This is important because a person may say, “I need an AutoCAD 2015 file,” when what they actually need is a DWG file saved in the AutoCAD 2013 format.
Therefore, understanding the DWG format is just as important as knowing the AutoCAD release number.
Can You Convert an Older AutoCAD File to a Newer Version?
Yes. However, there is an important distinction.
Newer versions of AutoCAD can generally open older DWG files directly. Therefore, you may not always need a dedicated converter simply because you are moving from an older version to a newer one.
For example, a newer AutoCAD release can open and edit older DWG formats. After opening the file, you can then save it in the newer version’s format if required.
The bigger compatibility problem usually occurs when moving in the opposite direction:
Newer AutoCAD → Older AutoCAD
In that situation, conversion is often necessary.
Using DWG TrueView as an AutoCAD Version Converter
What if you do not have AutoCAD installed?
This is where Autodesk DWG TrueView can be useful.
DWG TrueView is Autodesk’s DWG viewing software and can also be used to convert drawings so that they work with older versions of AutoCAD. Autodesk currently lists viewing and conversion among its DWG TrueView capabilities.
Therefore, if someone sends you a DWG file and you do not have the full AutoCAD software, DWG TrueView may provide a practical solution.
The general workflow is:
- Install DWG TrueView.
- Open the DWG file.
- Locate the DWG Convert function.
- Select the required output version.
- Choose the conversion settings.
- Convert the file.
- Open and verify the converted drawing.
This makes DWG TrueView particularly useful for users who need to convert DWG files without purchasing the full AutoCAD application.
Things to Consider Before Converting an AutoCAD File
Although converting a DWG file can solve compatibility problems, you should not treat the process as completely risk-free.
- Potential data loss
- Custom objects
- Dimensions and annotations
- External references
- Always preserve the original
Best Practices for AutoCAD File Version Conversion
To make the process safer and more efficient, follow these practices:
Keep the original file.
Always create a separate converted copy.
Confirm the recipient’s AutoCAD version.
Do not simply guess which DWG format they need.
Use Autodesk-supported tools where possible.
AutoCAD’s Save As and DWG Convert tools, as well as DWG TrueView, provide reliable options for DWG conversion.
Check the converted drawing.
Open the converted file and inspect important project elements.
Use batch conversion for multiple files.
If you are dealing with many drawings, DWG Convert can save considerable time.
Keep a clear naming system.
For example:
Building_Plan_2026.dwg
Building_Plan_2018_Format.dwg
This makes it easier to identify which file should be shared.
