I've done a partial CUIx in 2010 (attached) containing a Ribbon panel and a tab containing that panel. I can't seem to persuade AutoCAD 2010 to use that Ribbon stuff. I've set the tab settings to merge, but no merging happens. I've attempted to get things showing up by using the Customize Workspace button in CUI and turning on the appropriate check box, but after doing so there is no sign of the panel or tab being visible in the Ribbon right-click menu or in the CUI Customize Workspace tree in the top right panel. No, I can't use Transfer, I need to point at the partial CUIx, not copy its contents into the main one.
Have I missed something, or is this as broken as it looks? Has anybody else got it working?
Doing this manually is one small step, but if the Ribbon contents merge is not going to happen automatically on CUILOAD, I will need to do it under program control, like (menucmd "P...") for pull-downs. I haven't found any documentation about how to do this. Any clues?
