... concerning Freehand_BSpline tool in CurvesWB.
Trying to generate a logarithmic spiral only by means of sketcher (and not by a mathematics Macro)
https://forum.freecadweb.org/viewtopic.php?f=3&t=71338
I used the Freehand_BSpline to generate the final curve in a parametric way (DraftWB BSpline is not parametric!).
It seems to work, but looking at the Comb tool it isn't perfect smooth (low grade polynomic approximation?).
Interpolation_Curve has similar problems.
Not understanding the "Points" and "Tangent" feature and their purpose in the property tab,
I know that especially the Log-Spiral must have simple tangent-properties ( similar to Loxodrome in navigation).
Are there any hints by documentation?
