How to copy part of the model along with texture coordinates?

Hello,
I have a 3d model with existing texture (UV) coordinates. I’d like to make it bigger by cutting and pasting a section of it in the middle. Can I do that while preserving texture coordinates assigned to the pasted fragment? The model itself is linear and sections are clearly visible.
Thanks,

Joe

Hello,
It looks like vertex properties (including UV/texture mapping coordinates) are copied when vertices are copied. I solved my problem by creating new objects from selected faces, then copying and pasting the object/fragment I wanted to duplicate and joining all parts back together. Texture mapping was preserved during this process so it all worked out fine.
Thanks,

Joe
