Illustrator combining several shapes into one shape

[pslane]

I have an object that is made up of several small shapes. I know how to group it but how do I combine it permanently? It needs resizing and every time I try this, the separate objects go out of line.
Thanks.

If you want to maintain different colors for each shape, you can't combine them into a single shape.

I don't want them the same color. So if I make them all the same, then what?

 

[pslane]

Disregard that post. I do need them to stay in 3 colors. :redface:

Is there any way to resize it like that? With all the shape staying in place?

By resize I assume you mean scale. Select everything then use the free transform tool.

What Hawkeye said. If everything is grouped together, any sizing should affect all shapes equally.
