Length snapping by code?

[TBoy]

How to modify settings appearing in Window > ModelInfo > Units by script?
For example: Set Units to CM, Precision to 0.0, Length Snapping to 10.
Can someone post an example code please?

# Default code, use or delete...
SKETCHUP_CONSOLE.clear if defined? SKETCHUP_CONSOLE
mod = Sketchup.active_model # Open model
ent = mod.entities # All entities in model
sel = mod.selection # Current selection

opts = mod.options
prov = opts["UnitsOptions"]


#LengthFormat
puts "Old setting ;" + prov["LengthFormat"].to_s
prov["LengthFormat"] = 0
puts "New setting ;" + prov["LengthFormat"].to_s

#LengthUnit
puts "Old setting ;" + prov["LengthUnit"].to_s
prov["LengthUnit"] = 3
puts "New setting ;" + prov["LengthUnit"].to_s

#LengthPrecision
puts "The original precision setting value ;" + prov["LengthPrecision"].to_s
prov["LengthPrecision"] = 1
puts "The new precision setting value ;" + prov["LengthPrecision"].to_s

#LengthSnapLength
puts "The original SnapLength setting value ;" + prov["LengthSnapLength"].to_s
prov["LengthSnapLength"] = 10.cm
puts "The new SnapLength setting value ;" + prov["LengthSnapLength"].to_s
