I'm sorry, you need the extension for Revit from subscription center or any place on the net. Download and install then you can see this add-on.
Hope this helps.
Please could you tell me how can I establish the link Revit - ASD? in my Revit 2014 I have not a tab called Extensions at all and cannot find anything to downlaod. Thanks for your kind help.
If you're student ,then you can download the installer from student download center here
If you are not , you have to get it from subscription center.
Hi, I have got the subscription now but I have got no clue how to find the link. Please could you tell me what is the name of the file or send me a link? thank you very much in advance
