Il faut faire un cadre en bleu et sur l'origine dans le sketch pour que la fonction calcul les proportions.
Encore des questions?
...
par contre j'ai un bug avec sketch on surface: on ne peut pas effacer la fonction. à signaler à Chris_G
Je confirme le bug

C'est corrigé. Merci.

Hi, In CurvesWB, I have this to_console command : to-console.png And it works for multiple selection too : >>> ### Begin command to_console >>> doc1 = FreeCAD.getDocument('Unnamed') >>> o1 = doc1.getObject('Freehand_BSpline001') >>> e1 = o1.Shape.Edge1 >>> o2 = doc1.getObject('Extrude') >>> e2 = o2....

In your CopyMoveandRotateSketch function, you do this : Copy.Placement = newplace It means that you are replacing Copy's placement by a new one Sketch2 = CopyMoveandRotateSketch (Sketch1, 0.0, 0.0, 0.0, 0.0, 180.0, 'X') Sketch2.Placement # returns : Placement [Pos=(0,0,0), Yaw-Pitch-Roll=(0,0,180)] ...

What is your goal ? If you can stay at the topology level, you can create a wire made of edges supported by different types of geometry (line, Bspline curve, conics, etc ...) This way, you don't loose the geometric type of the edges. line_segment = Part.LineSegment(v1,v2) bs_curve = Part.BsplineCurv...

Hi,
I have not tested, but this should work :

Code: Select all

curve = Part.BSplineCurve(matriz)
          if obj.CreateFace == True:
          	line = Part.BSplineCurve([FreeCAD.Vector(x0,y0,0),FreeCAD.Vector(x,y,0)])
          	curve.join(line)
                sh = Part.Face(Part.Wire(curve.toShape()))

I think the sketch is not valid.
There is a short edge inside the highlighted circle.

EDIT : Geometry #57 (Circle with radius 0) must be deleted.

The "junction" points are duplicated.
That creates an interpolation error.
You can change your ranges to :

Code: Select all

for i in range (0,30,1):
...
for j in range (30, 90, 1):
...

Happy new year, I hope your wealth health is going better.
It is a great pleasure to follow this build journal.
Thanks a lot.

SoText3 is a real 3D node.

Chris_G

SoText2 is not influenced by some transform operations :

The SoText2 class is a node type for visualizing 2D text aligned with the camera plane.SoText2 text is not scaled according to the distance from the camera, and is not influenced by rotation or scaling as 3D primitives are.
