Hi Chris,
i using sketchu pro v7.
while using the tool, it is bit difficult to understand, which color is applied for which slope. i need to calculate, hw the tool is working?
is there any color which defines slope (like 0-5% or 5%-10%) in slabs? i mean say 'red' for slope slab 0-5%
u wrote highest color no. is for low gradient and vice versa. u also wrote to explode the group (containing the terrain) and select color and make a new group out of those.
i tried but found it little tidious... 
althought it is much simplied then what we do manually.. 
but i need to understand more about your tool.
u also made a new one for v8 where it is called 'Color by slope stepped'. i found the previous one more relevant for my work.
so i need to know that can the tool defines colors w.r.t. slope in slabs (like 0-5% or 5%-10%) ?
regrds,
rather i had changed name of the tool as 'Slope by angle'
