Absurd file size!
-
First try purging all materials and components. On a PC, go to the menu Window>Model Info>Statistics>Purge Unused.
Then save your file and compare before and after file sizes. See if that does the trick.
This works because SU will save all components and materials and styles that were ever placed in the model, even if they have been deleted. They are still saved in the file. So purging them will remove them entirely from the file, thus saving lots of file size.

Also do not use bigger image files (for materials) than 1024x1024 pixels. These images will count in the file size but due to OpenGL limitations, SU will degrade them to this size anyway.

If your feeling very keen you could also make sure any textures you imported are saved as small as you can get them, if you save as a .jpg in an image editor there is usually a quality slider so you an get the file size down.
The other thing that comes to mind is the effect mentioned in this thread: http://www.sketchucation.com/forums/scf/viewtopic.php?f=15&t=12618
Check out adamb's post and then the test by chris for more info.

As said before, purge the model. (Ensure that there isn't any hidden geometry that doesn't need to be tehre.) Then if the size is still large, go through your materials and ensure your textures are stored in a compressed format. I prefer PNG formats as they don't loose any quality, but JPEG can work as well. Anything that isn't PNG or JPEG you should resave in another format.

thks guys... i will ensure myself that my model is all purged and the textures come from a low sized image
if it doesn't help i will let you know! -
i've purged everything in my model and the file size reduced from 30mb to 6mb...
thanks guys, really apreciate that!

guys, another problem just popped up... sometimes when i purge my materials and i hit render, a message comes telling that kind of a native material is missing............ and it take a very long time to just start rendering...... why is it happening????
-
Which render engine are you using?
-
vray..

It happens when you're created a Vray linked material from an SU material and then later you deleted the original SU material so Vray can't link it to it anymore. The solution is simply to have a look at Vray's material list and delete any that are linked to deleted SU materials.
Hope this helps,

this will help for sure! thanks man!

Just to add one more tip for anyone stumbling across this later on...I've occasionally had a weird issue where even purge won't take care of a massive file size. It's been awhile but I think it tends to occur when you sometimes when you delete big chunks of a model as I recall.
Anyway, the end-all be-all purge is to turn on all your layers, copy everything and paste into a fresh drawing. This has helped me a couple times in the past.
