Re: BSpline in gleiche Abstände zerlegen

... Punkte in irgendeiner Weise parametrisch auf einem BSpline zu "verteilen" gibt es ja bereits in der CurvesWB. Aber macht es Sinn, das konstruktive System BSpline im Sketcher nochmal zu unterteilen/splitten? Wenn man einen BSpline anlegt, sollte man schon wissen, was man damit vorhat. An die inne...

Re: Rund- auf Rechteckrohr - Ausformung nicht korrekt

... mit Thickness, 3D-Offset und purem Loft kriege ich auch nur Fehlermeldungen (FC.18.4) oder verquastes Zeug => hoffentlich ist das Nachstehende eine korrekte Lösung. Etwas umständlicher gebaut sieht's so aus: Edit: Ich habe mir überlegt, ob man sowas nicht auch für ein Abkanten vorbereiten könnte...

Re: Importing from FreeShip to be used by FEM?

... converting the hull to a rounded (BSpline) Form: Offset is possible on a Gordon shell - but it is a little bit kinky near the bow. It is able to cut off this region by a cube and place there a round bow. The Gordon surface gives a nice mesh under Mefisto and 200mm max. edge length. I only can su...

Re: Importing from FreeShip to be used by FEM?

... unfolding = plate development?
In FC there are unfolding tools => especially unfolding mesh.

Re: Importing from FreeShip to be used by FEM?

... I supposed the boat should be a hard chined boat and scaled it up to 12m.
Planking 50mm (or less). From Ruled_Surface planking I made a PartWB fusion.
File is too big for presenting here (1500kB).

Re: Importing from FreeShip to be used by FEM?

... I had also problems with the points cloud. You can get it from test.stl via "display only points" and from test.asc via import. But if I tried to connect these points by CurvesWB "Interpolation_Curve" they don't get green. I also had repeatedly de- and activated "selectable" in the points proper...
