Hi there, I'm working on this London double decker bus http://www.2shared.com/uploadComplete.jsp?sId=FHXJHqoO0Vbhh6WSUnfortunately there are much things that I am not able to do, and I've got lots of problem trying to sort everything out. I really need some help and I would be more than grateful if anyone of you can help me because I'm really struggling to finish the bus (which has to be done by Sunday) :SCheers from Spain :-)

Can you provide us with a list of the things you have to do and where you need the help?  You have left it kind of opened ended at the moment.  I could think of a dozen things right off the bat without a moments hesitation.It looks like the bus is 3D.  Did you use surfaces or solids?

Hi John. The whole bus is a solid done (with extrusion) and we have added materials (such as translucent crystal) with surfaces.-We are struggling to get all the crystals right.-We can't copy the headlight on the front side (we have one but we can't copy it onto the other side).- We are also really having problems trying to "empty" the inside part and putting the "floor".-We can't also give thickness to the windows.I think that is pretty much it, we are working really hard on the project, it's our first one with autoCAD but it's becoming so frustrating...I wonder if I could get a little help, you'd really make my day.

If you reorient/relocate your UCS you can mirror the headlight to the other side of the bus.You can create a void inside the bus by subtracting another solid.  Then you can create a floor and use the union command to attach it to the rest of the bus.You can use the extrude command to give thickness to a window.It sounds like you are applying materials.  Is that right?  Materials can be applied to individual objects or they can be assigned to a layer.
