Default How to create car door - straddling 2 poly mesh

Hi All...i'm a complete newbie to the Maya app and am looking to model a car using the app. I'd like some help with creating the door on the car. I imagine this is something easy for most of you, so please bear with me.

So, I've got to stage where I've got the car main parts in separate main pieces. Converted to poly from nurbs.

The door straddles two poly mesh pieces (see pic) which are currently separate & each with big difference in poly count.
http://s211.photobucket.com/albums/...reatingDoor.jpg

Is it a case of merging these two polys? and then moving the relevant verts over the door crease?

Is there a tool which when merging the meshes, ensures the polys are uniform throughout which would make creating the door crease easy by moving the verts?

Please provide step by step guide.

Thanks

Ok first off the link you posted doesn't work for me so I'm basically guessing about your question.
If you are talking about the car door it'self being seperate from the chassis then there is no reason to combine it and it would be perfectly ok to have that as a seperate object.
If you want a way to create a door with same geometery as the chassis ,one option would be to select wireframe on shaded under the view menu in the view you are working in and then select the edges down one side of the hole in the chassis where the door would go and then extrude them out several times along the x axis matching the bottom verts as you go.then tweek the shape to match.
Another would be to select the edges both side and go to the bridge tool options and set the number of divisions to match and then apply the bridge this will give you minimum tweeking to do , once you have it bridged just right click and select the faces and under Mesh click on the extract option box and turn of seperate faces then estract those faces giving you a door you can then give thickness and shape too.

Hi Thanks for the response. However sorry to be a pain but your advise is based on not having the door in the first instance & creating it from the 'hole' within the mesh. whereas I'm trying to cut my Door from existing mesh poly (which originally resulted from combination of 2 separate poly's) I've repasted the link to the sketch i did:
<center>
<a href="http://i211.photobucket.com/albums/bb28/m12ben/Efijy/CreatingDoor.jpg" target="_blank">
<img src="http://i211.photobucket.com/albums/bb28/m12ben/Efijy/th_CreatingDoor.jpg"></a>
</center>

I've combined 2 mesh polys together where each represents:
i) the Wheel Arch (more of a mud guard than wheel arch like old style cars) &
ii) the section where the door would normally be (although this is a piece which runs from the front right through the back)

The door has to straddle borh original meshes. The polys on the resulting combined mesh are not uniform. If I simply cut a hole out, I'll end up with tris. Should I do this?

Thanks

one solution is to cut the door out with the split polygon tool then to clean the mesh resplit , reroute or delete the edges to loose as many tri's as possible .

yes once you have drawn the shape of the door with split polygon tool you can select the faces and extract them.then clean the mesh on the chassis and the door.
