thx for responding.

Yes, licence installed, rebooted..etc. The drop down menu seems to work but the options are all greyed out. I'm admittedly very new to this, but despite all the component tutorial videos I've seen (creating the object within a wall, creating component, etc...), I cant figure out what I'm missing for the ext to work.

Has anyone had issues installing / getting double-cut to work? I purchased and added the extension using the extension manager,and although it shows to be installed, enabled (and even shows up under 'Extensions' as an option on the pull down ribbon), but the pull down menue task list is all greyed out except 'Licence...'. What am I missing?
