@AgenceMarianRubio Do you have DynamoFormaBeta for 2.x package installed? We have seen this error when this version of this version of Forma package is installed in Dynamo 3.X as it is not compatible with the version of Dynamo you are in. You can use DynamoFormaBeta package.
I tried to installed the package but it’s dosen’t work. I view this message :
Can you please uninstall DynamoFormaBeta for 2.x package and then install DynamoFormaBeta package.
You can delete the package as shown in the image below. Dynamo will mark this package for deletion at the next start. So, you need to close Dynamo and the host (Revit/Civil3D) and restart again. Another way to do it is by deleting the packages from package folder.
ok I have problem with DynamoFormaBeta too
but the file open with error
So, looks like uninstalling Forma package got rid of the HelixTookit.Wpf.SharpDX error for you. That's a known bug as DynamoFormaBeta for 2.x package is not compatible with Dynamo 3.5. From the screenshot, I can't see what's upstream in your graph to point to the first node that is throwing the warning. Nor can I see the warning message. What does the warning say now? Can you share a screenshot which captures the full graph and also make sure you have the node preview bubble open so we can see the outputs from each node.
