How can I use structures from structure blocks in multiple worlds on Xbox One?

Solution 1:

Sadly structure blocks only save to the world file on bedrock console edition. If you have windows 10 edition you can export files to .mcstructure files which can be placed inside a behavior pack to be loaded and used at will, but this can't be done on just xbox.

Work arounds are:

• Build the structure once in each world you need it. You can use a structure block to save the structure to that world. You only need to do this once then you can build the structure as many times as you want.
• Get windows 10 edition, build the structures and export them as .mcstructure files. Create a behavior pack. Run a Bedrock Dedicated Server on a pc with this behavior pack on the same network as you xbox. Connect to the server as a LAN game on Xbox and then you can use the structures.
