angleTo funciton returning nan

[Joshua.mursic]

Hello, I am having an issue with the angleTo() funciton, it is returning 'nan'. Am I doing something wrong?

# Define Stock
stockCenter = adsk.core.Vector3D.create(0,0,0)


# Define Part
partBox = partBoundingBox.copy()
partMax = partBox.maxPoint
partMin = partBox.minPoint
partCenterX = partMax.x - ((partMax.x - partMin.x)/2)
partCenterY = partMax.y - ((partMax.y - partMin.y)/2)
partCenterZ = partMax.z - ((partMax.z - partMin.z)/2)
partCenter = adsk.core.Vector3D.create(partCenterX,partCenterY,partCenterZ)
angle = stockCenter.angleTo(partCenter)

Hi @Joshua.mursic ,

I believe that your problem is with the definition of the stockCenter vector, which defined as (0,0,0) does NOT have magnitude; (it is like a point instead), so no way you can determine the angle to the other vector you build later.

Try changing (0,0,0) by (1,0,0) just to try if you get some value from your code.

Then decide how it should be really calculated.

Hope this help.

This was exactly correct, thank you.

.... what about saving on compute time and keyboard strokes ...

from ...

partCenterX = partMax.x - ((partMax.x - partMin.x)/2)

to

partCenterX =  (partMax.x + partMin.x)/2.
