A simpler snippet:
var text3d:TextField3D = new TextField3D("Helvetica", {text:"Vector Text!",
size:100,
textWidth:2500});
text3d.material = new WireColorMaterial(0xFFFFFF);
text3d.bothsides = true;
text3d.x -= text3d.objectWidth/2;
text3d.y += text3d.objectHeight/2;
_view.scene.addChild(text3d);
var extrudedText3d:TextExtrude = new TextExtrude(text3d,
{subdivisionsXY:2, subdivisionsZ:2});
extrudedText3d.pushback = true;
text3d.pushfront = true;
_view.scene.addChild(extrudedText3d);
extrudedText3d is a mesh, so now you can do:
extrudedText3d.material = new WireColorMaterial(0xFF0000);
