Sketches on plane along a spline

[ione_ianniruberto]

Hi, I have created a plane along a spline like in the figure. Now I want to create a sketch on this plane. I create the circle in the plane and as the center of the circle I want specifically the point of the spline in corrspodence of which the plane has been created. I try to put zero but the code gives the result in the figure. The code that I wrote is this:

spline = sketchnurb.sketchCurves.sketchFittedSplines.add(points)

distance0 = adsk.core.ValueInput.createByReal(0.0)

planeInput.setByDistanceOnPath(spline, distance0)

plane0 = planes.add(planeInput)

sketchplane0 = rootComp.sketches.add(plane0) #PianoVALVE

circleplane0 = sketchplane0.sketchCurves.sketchCircles

circle01 = circleplane0.addByCenterRadius(adsk.core.Point3D.create(0,0,0), 0.85)

circle02 = circleplane0.addByCenterRadius(adsk.core.Point3D.create(0,0,0), 1.05)

profilo01 = sketchplane0.profiles.item(0)

profilo02 = sketchplane0.profiles.item(1)

I don't know what else to do. Can someone please help me?

Thanks

For some reason, the origin of the construction plane is not created on the spline. I'm sure there's a reason for this but it's not evident to me.

However, there is a workaround. If you replace these lines

circle01 = circleplane0.addByCenterRadius(adsk.core.Point3D.create(0,0,0), 0.85)
circle02 = circleplane0.addByCenterRadius(adsk.core.Point3D.create(0,0,0), 1.05)

with this

circle01 = circleplane0.addByCenterRadius(sketchplane0.modelToSketchSpace(plane0.geometry.origin), 0.85)
circle02 = circleplane0.addByCenterRadius(sketchplane0.modelToSketchSpace(plane0.geometry.origin), 1.05)

you should achieve the desired result. This substitutes the centerpoint with the origin of the construction plane which is in fact on the spline.

I Hope this helps!
