Arrow attribute changes unexpectedly

[varalflip]

I've created a clock (thanks for the help, Bruce!):

I'm new to Glowscript, but this behavior seems incorrect to me: if you remove the following statements:

    pointerh.length=SizeHour
    pointerm.length=SizeMin
    pointers.length=SizeSec

the arrows revert to length '1'; however, they should remain unchanged because I only changed the .axis attribute in the previous statements. Other attributes do stay the same (like color, etc.). Am I missing something?

Please see the description of axis and size in the Help section "Choose a 3D object > Overview":

http://www.glowscript.org/docs/VPythonDocs/cylinder.html

These two attributes are coupled, which has various advantages. In the case of arrow objects, it facilitates showing the changes in a vector quantity simply by changing the axis attribute.
