I'm no expert but going from the piccy it looks like each bit of the bonnet is it's own piece.

Even though you have combined all the bits, the easiest way to fix this would be to either:

very nice so far. Keep up the great work.

Good luck with the comp

Here's something I tried that may help you:

First I set the custom polygon display to show hard and soft edges (display/custom polygon display....). This makes the hard edges show up as solid...

Thanks for all the comments peoples. I will try to make more progress on it as time permits. Still lots of little bits to do to clean up.

Yes this is 100% Maya.

Here's a rear end view as well.

The body is sub-d's, the tyres are nurbs, the hubs and mirrors are polys. I just wanted to have a play and use everything to see what you could do with each....

It's taken ages and a lot of experimenting but I have learnt a lot at the same time.........

Future progress may be slow due to work and family........

I had a look at your file and to be honest, I don't know enough about it to see what the problem is. I did manage to find the cones in 2 of the 3 poles though.

He is a pic of a poly gear I made...

A planar surface can have objects intersect it and then have an area trimmed with relative ease I believe.

Try this:

1. Create a planar surface
2. Create a nurbs cylinder and make sure the...

oops......... wrong picture posted above. This one more clearly shows the teeth

I did this in about 1 hr. It is made from nurbs curves that have been extruded or had planar surfaces created from them. All surfaces are nurbs.

Everything has been circular filleted and trimmed...
