Thanks Glouglou.
Pipeshell should be fixed now.

...
Arc by 3 points : why not
Arc by 2 points + radius : this already exist in 2D (sketcher and maybe Draft), and it is not enough to define a single curve in 3D.[quote=GlouGlou ...

Both of these exist in Draft, Draft_Arc, and Draft_Arc_3Points.

draft WB features doesn't be linked with parent shape.

Suggested improvement:
SplitCurve on an unique a point with a mm dimension, that's could be parametrize able.

... or grant a display on DataTab, where the the original length of the curve (to be splitted) is given.
Then one can calculate it "exactly" in %.

It is already possible to enter mm values, from curve start (positive values) or from the curve end (negative values) :

... got it!
I always was seeking for an alternative way to display a fiber winding pattern on a pressure sphere (aerospace).
Split_Curve and Interpolation_Curve are another solution.
(Interpolation_Curve is not exact, compared to great circle construction with Blend_Curve)

I have added 2 new properties to SplitCurve :
- Distance : is a single-value field that is expression-ready
- Cutting Objects : will cut the curve at its nearest point

... I found another useful application for Split_Curve.
Up to now I couldn't design a clinker built boat => the planking already Wikings used.
Discretized_Edge only delivers equally spaced frame points.
With Split_Curve it is possible to produce parametric and controllable distances for more than one point.
The produced clinker planking example isn't perfect and needs still more work.
But the idea and the feature rises some hope.
( when using Interpolation_Curve better check "Detect Alignment" to false )

Very nice Chris!
Curve Wb is becoming perfect!
