Weekly design challenge 2026-W46

A reading room

A small public reading room full of daylight: shelves, tables, a quiet corner and a way in from the street that invites people inside.

How sharing works

  1. Press Share

    On any model of yours, press Share at the top of the board.

  2. Share it with the Community

    Open the link to anyone, pick the kind of building and choose whether your name shows.

  3. People build on it

    They open it, walk through it and make copies of their own. Share tells you how many.

Questions

Is it free?

Yes. Opening, copying and sharing models is free; a copy needs a free account.

Can people change my model?

No. A shared model opens read only. Someone who copies it changes their own copy, never yours.

Can I take it down?

Yes, at any time: set the model back to Restricted in Share, or delete it, and it leaves the Community within a minute.

What do I need to open one?

A browser, on any computer. Every model can also be saved as IFC for other BIM tools.

Draw it once. Share it with everyone.

The next model someone copies could be yours.
