Possible to change size of a vizshape.addBox object?
 

Is it possible to getSize and setSize of a vizshape.addBox object?

There is nothing about this on the documentation.

Yes, it is possible to get and set the scale of a vizshape object.

box = vizshape.addBox() #define box
box.setScale(2,2,2) #change scale by 2x
box.getScale() #get the scale

Best,
