For some grid types it is possible to convert the shapes of a puzzle from one grid type to another. That means the base grid type of the puzzle is exchanged, the solutions are deleted and the shapes are replaced.
Currently the following conversions are implemented:
To do one of those conversations choose File - Convert . A Window will pop up showing you to what other grids you can convert the current puzzle. If no grids are available a message will display this information.
You then choose your intended target grid and confirm. That's it. Useful is this if you need big shapes in the rhombic grid that would be a lot of work to assemble manually in those grids. On the other hand: this tool requires a bit of planning ahead because you first need to create the prototype shapes out of cubes then convert and then perform the final modifications.
