The question was: "I am trying to increase the stick radius for Sketch_stick. I edit the stick radius datablock, read it in, but my sticks remain unchanged."

Alwyn replied: "The setting of sketch parameters was improved in O 5.9 but the manual was not changed regarding the use of the datablock .sketch_radius by the sk_stick command. That is not used anymore, so to change the radius use the sk_setup command."
