BrushFill biglines.htm  - Check this to enable the BrushFill Mode & Style Sliders.

If the checkbox near the GridRed slider (bottom left) is set then the Mode and Style sliders are enabled and the captions for the Line and Item controls, just to the left, are changed to show the Mode and Style slider values respectively.

If you use very large DrawWidth sizes you will find that many of the grid features will be obscured. In the following example you can see that if you uncheck the bottom left checkbox the DrawStyle (come DrawWidth) selection will be disabled and a replot of all selected grid features will be made.
