Press The Blue Button in the center,Idk if will work,but Try.

First, have a set built. This is obvious.

Second, go to your "Sets" tab and create a set. A blank set will be made with a default thumbnail.

Third, click "edit" under that set. It will bring you to the workshop.

Fourth, load you .brk file into your window.

Fifth, find a good camera angle and stay there. That will be your thumbnail.

Sixth, click "Publish" on the toolbar at the top. Enter your logins, and your set will be placed onto the website.
