Multiple meshes access in C#

Hi,

i have imported an 3d object in Unity that have 2 meshes how can i access these meshes in C#?
if i do something like gameObject.GetComponent("name of the mesh").tranform.rotate(0, 10, 0);
this works perfectly this.tranform.rotate(0, 10, 0); but i want to rotate only 1 mesh not whole object.

i get the error :
Object reference not set to an instance of an Object C#

thanks in advance,

 

Transforms are a component of a GameObject (they're always attached which is why you're able to use the shortcut). If you want to control multiple meshes individually then you will need to create multiple GameObjects.

 

i was able to manipulate/rotate a part of the gameobject by using this code
this.transform.find("name of the part").rotate(0,10,0);
