Miscellaneous Editing Tools

The Tools subtab (Figure Tools ) offers extra editing tools. Currently only some constraint related tools are available.

Constraining Tools

These tools are mass editing tools that have an impact on the possible placements of the pieces in the final result. They act either on the inside or the outside of the shape. Voxels that are considered to be on the inside are voxels that have another voxel adjacent to all of their faces. Consequently, outside voxels have at least one empty voxel neighbouring.

:

Fixed Inside/Outside - These functions allow you to change the state of the voxels that are either on the inside (left button) or on the outside (right button) of the shape into fixed voxels. Although one can think of situations in which these can be useful as such, they are mostly used to undo the effects of the next two functions.

:

Variable Inside/Outside - These functions will respectively make all the voxels on the inside or the outside of the shape variable. Making the inside variable is very useful for puzzles with internal holes in undetermined places. On the other hand making the outside variable can be helpful in a lot of design situations (e.g. adding extensions to the pieces). Clicking both buttons will make the shape completely built out of variable voxels. Use these wisely as the more variable voxels there are, the slower the solver will run.

:

Colour Remover - These buttons will remove any custom colours from the voxels that are either on the inside or the outside of the shape, and replace them with the default colour. Removing the colour from the inside can prevent having to apply complex colouring to the result shape in situations were the colour constraints are relevant only to the overall appearance of the puzzle.

Depending on the grid the tab might contain more buttons with more actions. Right now the following additional tools are available

Fill Holes

This button will fill all internal, which means completely surrounded, voxels of the selected shape. This is useful for more complex grids, where is is not easy to see in the grid view whether a voxel is on the inside or not.
