Please read if you are currently using Autodesk ® AutoCAD ® /Civil 3D ® 2025/2026 version
In response to Microsoft ending support for .NET 8.0 in November 2026, Autodesk will be releasing in-place updates to AutoCAD and Civil 3D 2025 and 2026 to migrate from .NET 8.0 to .NET 10.0. Transoft’s products remain compatible with the following Autodesk CAD platforms:
AutoCAD and Civil 3D 2021 – 2027 (64-bit only), with supported versions varying by product
Except:
- AutoCAD and Civil 3D 2026 update to .NET 10 (to be released in August 2026).
- AutoCAD and Civil 3D 2025 update to .NET 10 (to be released in September 2026).
- AutoCAD LT.
To avoid any disruption to your workflow, we recommend:
1. Staying on your current AutoCAD or Civil 3D 2025/2026 version without applying the Autodesk in-place update, or
2. Updating to AutoCAD or Civil 3D 2027
- Transoft compatibility updates are rolling out across our product line.
- See our Product Compatibility page for current details.
Some of our CAD products may continue to load and operate on the new .NET 10 version of AutoCAD and Civil 3D 2025 and 2026 but have not been fully validated, so you must use them at your own discretion.
We're continuing to monitor this transition and may be updating as more information becomes available.
