Yes, you can, but I'm not sure sketchup is the best software for this purpose. Most people (Including the developers) use Blender. You can download it here: www.blender.org
I 110% back up the learning blender part. While initially grasping all the controls can be kinda daunting (I have been using it for over 10 years now and I literally just learned a new command last week ) it is well worth the effort to learn. Ketchup, on the other hand... well... not so much. That's actually what I started out on and let me tell you now... I really wish I wouldn't have wasted all that time learning it.
I can't tell if your kidding or being serious... I am going to guess being serious. I live in the United States of America (thus the joke)
