use the API to rotate an ellipse

[kmaccrimmon]

I am new to the fusion 360 API and I could not find any examples of how to rotate an ellipse. Here is the code I have so far.

        app = adsk.core.Application.get()

        ui  = app.userInterface

        design=app.activeProduct

        rootComp=design.rootComponent

        sketches=rootComp.sketches      

        sketch=sketches.add(rootComp.xYConstructionPlane)  

        sketchEllipse = sketch.sketchCurves.sketchEllipses

        #create ellipse    

        centerPoint = adsk.core.Point3D.create(0,0,0)

        vector=adsk.core.Vector3D.create(0,0,0)

        majorAxisPoint = adsk.core.Point3D.create(50,0,0)

        throughPoint = adsk.core.Point3D.create(0,25,0)        

        ellipse = sketchEllipse.add(centerPoint, majorAxisPoint, throughPoint)

        #rotate

        matrix=adsk.core.Matrix3D.create()

        matrix.setToRotation(30,vector,centerPoint)        

        sketch.move(sketch.sketchEllipse,matrix)

fusion is complaining about the sketchellipse which should be castable to sketchentites. 

Has anyone done this?

thanks!

Sketch.move ask for an object collection rather than sketch entities see the documentation here.

Also you can't rotate around a null vector !

Here is the fixed code :

app: adsk.core.Application = adsk.core.Application.get()
ui  = app.userInterface

design = adsk.fusion.Design.cast(app.activeProduct)
rootComp = design.rootComponent
sketches = rootComp.sketches      
sketch: adsk.fusion.Sketch = sketches.add(rootComp.xYConstructionPlane)  
sketchEllipse = sketch.sketchCurves.sketchEllipses
# create ellipse    
centerPoint = adsk.core.Point3D.create(0,0,0)
vector = adsk.core.Vector3D.create(0,0,1)
majorAxisPoint = adsk.core.Point3D.create(50,0,0)
throughPoint = adsk.core.Point3D.create(0,25,0)        
ellipse = sketchEllipse.add(centerPoint, majorAxisPoint, throughPoint)
# rotate
matrix: adsk.core.Matrix3D = adsk.core.Matrix3D.create()
matrix.setToRotation(30,vector,centerPoint)
objColl: adsk.core.ObjectCollection = adsk.core.ObjectCollection.create()
objColl.add(ellipse)  
sketch.move(objColl, matrix)

tykapl.breuil,

 it worked for me.  

I realized the rotation function needed radians so I updated to:

matrix.setToRotation(math.radians(90),vector,centerPoint)

thank you!!
