It looks like Wings 3D is a no-go.
One can group and ungroup meshes, but I can not find any limb or parenting capability.
Although it allows objects to pivot around their center point, it does not allow the movement of that pivot point to any location other than the objects center point. Makes it hard to pivot a tank gun up/down from its end point.
@ FPSCX10 LORD
Had a look through that list.
It looks like most of those will not allow me to do what I require.
I will have to have a closer look at Truespace, just to be certain, as I have not looked at it yet.
It is starting to look like I may have to learn Blender after all, unless some person can come up with another tool.
Thanks for all your suggestions.
WHY OH WHY O LORD IS LIFE ALWAYS SO HARD ???????
