Being an XSI newbie I am full of questions at the moment. This one is pretty basic but is quite puzzling:

I create three primitive polygon mesh primitives, (a cube, a cone and a sphere), scale them all to about the same size and then freeze them. I then experiment with parenting one to the other. All is as I expect until I parent anything to a cone. For some reason parenting any of the objects to a cone causes the object to be scaled up to about three times its size. If I drag the object back out of the cone and drop it on the scene root it reverts back to it’s original size and location. What is it about parenting to cones that causes this behaviour?

If you want to freeze their transformations, use : Transform - Freeze… ( in your case you might want to use “freeze scaling") Do not use “Freeze” under edit.

The reason you objects move is that the scaling of the parent is not froozen and you also have scaling animation on your other objects. To remove the animation do : Animation - Remove animation ...

Okay. So the primitive’s SRTs are not frozen by the freeze command under Edit. Got it! That answers alot of other questions that were brewing.
Thank you so much for that, Sebastien!
