Re: Curves workbench

Gives me in a test case ... This is a bi-cubic BSpline (same as Bezier in this case) surface. The rhino3dm api lets me create a UV surface with ... static CreateRuledSurface(curveA, curveB) This function creates a Ruled Surface , linear between the 2 input curves. You cannot create your bi-cubic su...

Re: Scripted Objects (FPO) API + Docs

I read the PDF. It looks great. I hope I can find time to give it a try.

Re: Split Curve-Cutting Object help And How to NoShow Bounding Box

1. I will be grateful if somebody will point out why the cutting obj split is not actually happening at the circled junction. BSpline & Bspline001 Because SplitCurves takes the shortest distance between objects to find the cut location. Here this shortest distance is at the curves start points,...

Re: Constraining BSpline destroys control nodes.

SketchOnSurface indeed removes internal geometries inside the Mapped sketch. This is done to avoid BSpline poles that would be outside of the bounding rectangle to interfere with the bounds calculation. This is not a very good solution. The first version of this tool didn't have the ExtraObjects pro...

Re: Curves workbench

It does not seem to matter how I access e.Curve I get an error <class 'TypeError'>: undefined curve type This error appears on degenerated edges (length=0, only 1 vertex). On RotationSweep, this faulty edge is the rotation center of the swept profiles. This same error also appears for example on th...

Re: Cryptic error messages

This should be fixed in the newest Curves update.

Re: Curves and solids weirdness

Do you have files to share ?
This would be much more useful to investigate than images.

Re: Texte en courbe et en relief

Bonjour JP, Mais pas question de modifier Fill Faces ni Thickness. Décidément, cet exemple de l'anneau plat est intéressant. En effet, quand les valeurs de Thickness ou Offset sont non-nulles, SketchOnSurface génère des surface décalées. Et on retombe sur le même type de problème qu'avec Part-Revolv...

Re: Texte en courbe et en relief

Je suis d'accord, le nom n'est pas terrible. C'est un héritage du passé : au début, on pouvait uniquement utiliser un sketch. Et puis, on code, on code, mais on ne soucis pas toujours beaucoup du nom, ça parait secondaire, alors que c'est important. Le nom qui me parait le plus correct serait MapOnS...

Re: Texte en courbe et en relief

Bonjour JP, En fait, SketchOnSurface fonctionne correctement. Mais la surface générée par l'outil Part.Revolve est un plan ! Donc SketchOnSurface s'applique sur le carré englobant l'anneau. Si je fait une surface réglée entre les 2 cercles, j'obtiens une surface BSpline qui suit bien la forme de l'a...
