Rhino.Inside AutoCAD V1.0.11 -- error on launch

Rhino.Inside AutoCAD
1

AutoCAD 2026.0.1 (W74.0.0)

Looking forward to giving this a spin. I just installed the plugin (V1.0.11), and I’m getting an error on launch:
ERROR loading Rhino.Inside.AutoCAD: eInvalidInput

On first launch, I did get the Security popup as well and selected “Always Load”

I do see the toolbar, but when I click any of the buttons, AutoCAD hangs for a moment, and then command line returns, for example:
“Command: RHINO Unknown command “RHINO”. Press F1 for help.”

Tried running the installer in ‘repair’ with no luck as well

Any thoughts on what this might mean? Or additional information I can provide to help diagnose?

Thanks!

@bushdylanj I am not 100% sure what would cause this, but it feels like a NET framework issue.

From what you describe, the plugin extension is not able to load the extension at all, and it is failing on initialisation.

My first thought would be to make sure you have the latest version of Rhino 8, as we need it to be in NET 8 to match AutoCAD 2025 and 2026 frameworks.

You may also be getting a more verbose error in the command line of AutoCAD when the eInvalidInput message shows, if you are can you share it?

Ah, you are correct about the command line, here’s what I see at launch:

I will try updating Rhino in the meantime

Thanks!

Updated Rhino, restarted PC

Same error still persists :confused:

The issue is AutoCAD trying to save the database and failing.

If I send a DM are you able to describe your set up so we can rule out a couple more things, and see if we cant get to the bottom of this one?

Yes for sure! Thanks

In case any others are also experiencing this issue, it has been fixed in the latest Version V1.0.12 - Download from the Website

@bushdylanj thanks for your help resolving this one
