We had this issue too, and you probably won’t believe me when I say so but…
Revit only supports 20 tabs (+ modify tab)
Now I know it says custom ribbon tabs. And Your 20 tabs include the standard revit tabs. However it does not seem like a coincidence that it stops at 20. I don’t believe Modify counts
Hey hey thanks for the reply.
I see what you mean but I am puzzled by this because I remember I had some long lists of tabs that were going to be placed in a drop down list (a little arrow to the end of the ribbon) and from the moment I have included this custom tab, the issue started. Maybe I am dreaming and it was never the case.
I counted the tabs in the first image and it makes sense up to a point
What doesn’t make sense, and now this is Autodesk stuffs is that I never hit that limit. Me the guy testing an average of 4 addins a week!
I am not sure if C# compiled plugins count. This is my revit 2024 right now:
I actually counted my tabs and I have 20. and therefore anything I add or remove, will allow the others to pop in the tab panel. Omg this is impossible…also because there is no way of removing or adding tabs directly from revit but I have to move hte plug ins from the folder system etc etc…not ideal. Bruuuuu…Oki I am sad now.
