Hi Rodrigo, your detailed explanation is correct. Auto option can be useful, if bezier curves are imported from somewhere - then smoothness turns automatically on when the previous control point, line point and next control points are on a straight line +-5 degrees.

Hi,
I am trying to better uderstand the line segment smooth option. Therion Book currently states that:
"* smooth <on/off/auto> -> whether the line is smooth at the given point. Auto is default."
From some tests I believe that the resulting behaviour could be explained in details as:
"* smooth <on/off/auto> -> whether the line is smooth at the given point. Auto is default. This setting only has any effect if both segments that passes through the point affected by the smooth setting are Bezier Curves (the one arriving at it and the one leaving it). On means that the line connection at this point will be smoothed, both by therion and by xTherion. Off means that smoothness at the point is not guaranteded. Auto means that, if both segments that passes through the point are Bezier Curves, Therion will automatically detected if they are smooth and, if they are detected as smooth, Therion will keep them smooth in it's transformations. xTherion always creates Bezier Curves as smooth, even if the previous segment was a straight one."
Is this detailed explanation correct? Is there any correction or inclusion that would be appropriate?
Regards,
Rodrigo
