Coordinates on sketch on YZ plane

[Anonymous]

I created a sketch on YZ Plane.

When I add a circle to the sketch I have troubles on coordinates of the center point

design = app.activeProduct
rootComp = design.rootComponent
keyCapOcc = rootComp.occurrences.addNewComponent(adsk.core.Matrix3D.create())
keyCap = keyCapOcc.component
sketches = keyCap.sketches
yzPlane = keyCap.yZConstructionPlane
sketch  = sketches.add(yzPlane)
circles = sk.sketchCurves.sketchCircles
pt = adsk.core.Point3D.create(0, 1, 1)
circles.addByCenterRadius(pt, 2)

When the circle is drawn, the center is on (1, 1, 0) on the component based coordinates.

For sure I'm missing something, maybe I need some transformation......

I'm pretty sure sketches use their own coordinate system (XY?) independent of the plane you put them on.  They're translated onto the parent plane (YZ in your case) of the sketch afterwards.

This is my opnion too.

The ploblem is how to get and trasform this coordinates system.

It should be a pretty common operation in creating sketches....

I found the solution myself:

pt = sk.modelToSketchSpace(adsk.core.Point3D.create(0, 1, 1))

Thanks for posting!! As it happens, I've got the exact same issue, and your solution looks like a life-saver!!  (I'm creating 3d sketch elements, on any plane, in any orientation - total mind bender...)
