How do I embed a web hyperlink into a piece of text within AC?. Can this even be done?
I know this is not the answer you are looking for, but you can add QR codes to you plans.
Please don't forget to integrate some of the URL shortening (and thus link management) services found online. This would be amazingly useful because you could then change the URL at a later date when the initial one has changed (due to vendor site restructuring for example). Even Graphisoft could provide such service at a profit.
