3D Illustrator looking to embed 3D files on my website

If you are usuing Dn you can publish your object on web and share or use embed code to place in your website.

i assume you want to view the 3D files instead of downloading them so the best option is to forget about Adobe and use 3rd party tool made to actually work

with the end of Muse this question belongs in the Dreamweaver forum, there you will find a few still teaching how web code works but i recommend this one to start you off
