Unhappy Modelling Problem (Essential)

Hello friends !

well I´ve posted a thread a few days ago, but it seems to bee, that I don´t wrote my real problem.

So, I´ve made some little images, where you can see my problem:

1st image: show´s the simply car - but I have deformations on it
2nd image: shows the same car with subdivisions 1 - and more ugly deformations on the mesh

you can download the maya file & images here:

maya file:
http://rieder.tophunter.at/3dproblem...ing_problem.mb




please, what I´m doing wrong ?
what is the problem & how can I fix it ?

thank you all for helping me,
bernhard

hwo are u sub it? are u goin to modify>convert polys to subdivisions? thats the way to do it. I wouldn't recomend going to poly> subdivide, doesn't work for what you are trying to accomplish. as far as the grey stuff, try going to edit polygons, normals, go to the options under soften harden, and make sure it is around 30 and hip apply. Let me know how it works out, hope this helps!

Question Modelling Problem

hello friends and thanky ou for helping me.

@kurt:
thx for the file - you´ve triangulated the mesh. well, the problems still exists, and I don´t want to triangulate my mesh.


@brian:
okay, what I did:

1. Modify-->Convert-->Polygons to Subdiv
I use 40000/64, and I don´t use "Keep Original" -because, if I don´t use "keep original" it is much more smooth.

2. I´be got an error message:
Error: polyToSubdiv1 (Poly To Subdiv Node): One or more edges is nonmanifold.
// Nonmanifold geometry cannot be converted to a subdivision surface.
// To clean up nonmanifold edges, use Polygons->Cleanup with the nonmanifold option. //

3. Polygons-->Cleanup
I´ve activated Nonmanifold geometry+Normals and Geometry


4. Modify-->Convert Polys to Subdiv
it worked, but it seems to be, that the mesh is now destroyed:



I don´t know where the problem is !!???

Maybe there is a problem with my normals - but I don´t know exactly what it can be.
The option "soften harden" with the normals works - okay, this is one point I understand, but I have the problem before with the damaged mesh.

@T-Rex:
Yes, that´s right Brian. My big problem is, that I modelled all my stuff before with cinema - but now I want to learn Maya - and I can see really more opportunities with maya. it´s really cool, but it takes a lot of time to learn - you know....


okay, so thanks for helping me,
bye for now and take care,
bernhard

Try to modell your car again. Try to start with a cube. The Polys Edge should be used to define the conture of your object.
Have a look at my attachment.

The "destroyed wireframes" will disapear, when you press "3" on your keyboard. 1,2 and 3 is for display detail.

Get involved with the use of crease edge tool, this will improve your modelling style when you use subdiv.

I've send more detailed information to your e-mail.
