Hi Jojo,
What you need to do is read your own code a bit better :)
You try to set the visible property to an Object3dLoader, not an
Object3D!!
private var obj1:Object3DLoader;
while you want show/hide an object3D;
you have declared them:
obj1object3d = e.loader.handle;
so just:
obj1object3d.visible=false/true
in your txtButMouseDown method.
Also you render on enterframe, clear all the render calls from your
txtButMouseDown method as well.
Since you do not use the ObjectLoader further in your code,
just do for the 3 loaders
var obj1:Object3DLoader = Obj.load("assetts/teapot_1.obj",
{ material:material } );
and remove the 3 class vars from your class.

It does view.render() in the onEnterFrame so I assumed it was ok.
I went overboard perhaps and put explicit view.render(); statements
after each obj.visible change ... still doesn't work
I really don't see why this should not work ...
I can certainly appreciate that looking at anothers code is annoying
at times but anyhelp is greatly appreciated.
Here's the code so no one has to take time to unzip ...

Do you re-render after changing the visibility? Like so:
myView.render();

nothing done in the onEnterFrame, however ... hmm ...
I think the logic of swapping is solid (the traces of objtoload look
good) so maybe the fact nothing is done in onEnterFrame is making it
fail?
The failure mode is obj1 displays and on button press obj1 stays and
nothing else appears. No compile or runtime errors. Subsequent
button
clicks increments objtoload (1 to 3) but nothing displays except
obj1.
I uploaded the little project (with assets) into the group upload
