Unwarpping Same Shape Different UV's

Hi there guys

I am having a problem with UNwrapping my UV’s, and maybe missing something. Here is a picture and i will explain:-



Now (A) is how i want it to turn out but (B) Seems to come out totally different. Does anyone know how i can get them to be the same and why this is happening?? All i did was copy them from (A) and made them alittle longer or shorter. I have about 6 others and they all turn out like (B).

Any help would be greatly appricated.

Thanks

Clinton

Ensure to clear object scale (Ctrl+A / scale) before unwrapping and change unwrap method between ‘Angle Based’ and Conformal to see which gives best result.

Richard thanks a lot. That did the job!! Really appreciate your help!!!
