On the BIMx.graphisoft.com Model Transfer site, each BIMx model has a share link for embed HTML, Twitter, Facebook and LinkedIn.
I think it would be useful to also provide a QR code image for the link. Enscape provides this for all of their hosted "panorama" views and I think it is useful to place those QR codes on the drawings so that people in the construction field can use their phone to pull up the link.
Thank you very much for the idea, this is an interesting one!
I am happy to say we took notice of this wish and I have added it to our Wish List database (please refer to it as Wish #13067). Hopefully, our Product Management team will adopt this one in the future.
