What should I use?

Question

I'm trying to make something like this http://www.keramikakanjiza.com/en/moj-ambijent/kupatilo002.html

I need to make a flash application that allows me to test floor tiles on a 3D scene using drag and drop (or any other way really).
I have couple of questions:
1) I was planing on doing this in ActionScript 3 since I haven't really done much flash before and I only worked in ActionScript a bit. Is there a better way to do this?
2) How do I go about importing a 3D scene into my flash app and making it "interactible"?
3) How do I change the texture of a floor tile on the 3D sceene? Is there a method for it or something? ( I thought about it like this: When the user drags the tile from the selection on the right, in the startDrag method i would take the texture of the floor tile and somehow "store" it in a variable or something and then when the user releases the mouse on top of a wall on the 3D scene it would change the texture of the wall to the "stored" texture. Is this doable or am I just talking nonsense?
Thank you for your time!

Answer 1

you can use the bitmapdatafill() method to add textures.  this should get you started:
var mc:MovieClip = new MovieClip();
addChild(mc);
mc.x=mc.y=100;
mc.rotationY = 45;
var bmpd:BitmapData = new A();  // import a bitmap and assign it class = A
mc.graphics.beginBitmapFill(bmpd);
mc.graphics.drawRect(0,0,200,50);
mc.graphics.endFill();
