Cube size

A cube is defined as being of size "n" if each face has (n) x (n) facelets. The program will accept any value of "n" in the range of 2 to an upper size that will be referred to as MaxCubeSize. The value of MaxCubeSize is adjustable. The upper limit is a function of the minimum facelet width setting. For most computers the program upper limit of 99 is achievable when scrolling is enabled for a minimum facelet width setting, excluding separator, of 2 pixel. However, if the marked centres option is selected via the Unravel Options dialog, the implementation of numerically marked centres will be restricted to the size range of 3 to about 32 when scrolling is enabled for marked cube minimum width of facelet excluding separator of 8 pixel. When the corner marking extension applies the marked cube limit can be increased to the same limit as for the unmarked case. For more details on the cube size limits applicable to cubes with marked centre facelets refer to the Maximum cube size section.

At start-up, the Cube Size dialog always initially prompts the user to enter the cube size value. In application program mode, the cube size value on exit for the previous time the application was run always appears as the value used for the start-up display of the cube. In applet program mode, the default cube size is always presented at start-up. By clicking Cancel (or OK without changing size) on the Cube Size dialog, the user selects the initial cube size value presented.

The size of the cube can be changed from the initially selected value without quitting the program.
