The layout grid in RadDiagram is a little lacking and it would be a lot more powerful if it supported a similar layout grid to Adobe Illustrator. The features of interest are: Grid Subdivisions - You specify the gridsize as currently, say 8px, but then you can also specify a number of subdivisions, say 2. This will split the 8x8px grid cell into four 4x4px grid cells, and allow snapping to the 4x4px grid cells. Grid to back/front - allow the grid to be overlaid on top or behind the diagram so that you can optionally see the grid all the time. See attached diagram. Thanks Reason for closing / declining The mentioned cells can be controlled with attached properties of the BackgroundGrid and BackgroundPageGrid.
