Re: Class-J yacht

... Chris it was your idea/proposal, to cut off "negative" shapes by boolean operations. Up to now I always tried to form the frame BSplines as is. And the BSplines should have an identical structure, to get a smooth shape. It was a difficult task, coming from S-shaped frames to neighboring U-shaped...

Re: Class-J yacht

... finally could do ChrisG's J-class yacht also with CurvesWB Gordon surface.

Re: Curves workbench

... 3 years ago this yacht was one of my first boat fevers as an FC freshman.
Today I tried to do this halfhull with Gordon - no result.
The same with a Loft on some or all frames - catastrophic.
ChrisG's shape is up to now the only form able to work with.

Re: Curves workbench

... 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 on...

Re: Curves workbench

... 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)

Re: Curves workbench

... 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 %.

Re: [gelöst] Mit welcher Workbench erzeuge ich eine 3D-Kurve?

... ich bin mir da gar nicht so ganz sicher, ob das ein Problem der CurvesWB (Chris_G) ist. Die "Vertex" Punkte existieren in der Sparte geometrische Primitives, also vermutlich Urgestein bei den CAD Tools. Das Transform Tool hingegen halte ich für später aufgesetzt. Verschiebt man einen Vertex mitt...
