Creation of Plane at Angle

>> note I think I have found a solution see bottom ?

Hi, I am currently using code like below to create planes for sketches that are in the XY plane and offset on the Z axis, I have a points array which I use for the sketch in which all of the Z values are on the created XY plane

planesObj = hullComponent.constructionPlanes
planeInput = planesObj.createInput()
xyPlane = hullComponent.xYConstructionPlane
planeInput.setByOffset(xyPlane, offsetValue)
plane0 = planesObj.add(planeInput)

I now need to perform a similar task except the planes offset along the Z axis will be tilted as per below

I have not been successful so far in the API doing this so if someone can point me to an example or other help it would be appreciated. I can obviously create the plane manually by creating a plane through three points (all of the points in the array to draw line in the tilted plane) but I need to perform this in the api.

Thanks in advance. Khim

Ok I think I have found an answer below ?

planeInput.setByThreePoints

Hi @dozerdroid .

Indeed, a three-point passing plane might be a good idea.

I made a sample of creating a plane of three points of passage while creating the points of the sketch.
