Hi,

If you go to Tools > SubTool > Extract, there’s a little circle in the “S Smt” control. When you click the circle it changes inner/outer appearance. What does that do?

Haven’t found anything about it in the documentation.

Thanks.

This small circle change the smoothing algorithm of the Smoothing applied to the extract, mainly a stronger smoothing.
