Use Revit Icons in my Plugin allowed?

[ricaun]

Hello everyone!

This week I update a plugin called ElectricalUtils and I decide to use some Revit icon that is used for de Power, Telephone, Switch, and other commands related to creating ElectricalSystem.

At the moment is a placeholder just for reference, from the user's perspective makes more sense to use the same icon. (The command is basically the same.)

I gonna recreate the icons but I still wonder if can I use a Revit Image resource in a plugin.

I'm not copying the icon to my plugin, I'm using the resource that already exists in Revit.

Like this is the reference for the ‘revit.ico’ - ”/UIFrameworkRes;component/ribbon/images/revit.ico”

I know that could change and break in the next version without warning but am I allowed to use it?

Personally, as a non-lawyer, I would say that you can use all Revit resources within your Revit add-in. I see no significant difference between making use of the Revit API DLLs (officially supported for Revit), the Revit Autodesk .NET automation and ribbon DLLs such as AdWindows.dll (officially supported for AutoCAD, afaik, but not for Revit, afaik) and the Revit resource DLL. Does the Revit license agreement say anything about this topic?
