The church inside and out looks just awesome. So much detail. The ornaments on the pillars, chandeliers, railings. This is just unreal.

Thanks for all the comments.
The lowest poly model here would be the T-34 with 290175 edges and 113783 faces. I was aiming at small file size which is only 2,8mb. The king tiger so far has 850214 edges and 338435 faces.
It's not difficult to make these track links. Each link is quite simple in shape and than you just need to copy it along a path.
I only use standard SU tools. Only plugins i have installed are Sketchyphysics and Kerkythea exporter. The only plugin i'd wish to use is subdivide&smooth by smustard.
All these models are done by me just as a hobby. I'm not a military enthusiast, i was just learning sketchup and i couldn't find an interesting topic. I came across some tank model in the 3d warehouse and wanted to do a tank myself. Before i finished my first one i already knew that i'll be doing another one. I find some strange joy in these machines.
If anyone wants to use these models for rendering, animations, texturing or anything they're in the 3d warehouse (all except KV1 and King Tiger). Just search for the tag "shareck".
There is only one pic of Abrams in the first post so i'm posting some more below:

Thanks for all the comments. As for the source materials - i use reference pictures from sites such as http://www.primeportal.net , http://www.svsm.org . Blueprints, technical data and pictures from Osprey New Vanguard magazines, and also http://www.smcars.net for blueprints.

this is deadly!!!

Now the British tanks:
Churchill Crocodile flamethrower tank:

Conqueror:

Challenger 2:

German tanks:

Panzerkampfwagen IV ausf.H (with older cupola) - my favourite one, still need to correct these floating nuts on the steering unit hatch.

Panzerkampfwagen V ausf.A PANTHER tank

Panzerkampfwagen VI ausf.H1 TIGER tank (my first tank model - wrong in so many aspects)

Panzerkampfwagen VI ausf.B KING TIGER (WIP my most detailed so far)

I spend from 8hr to about 30hrs or maybe even more on each tank. It's 3rd week now and i still havn't finished the King Tiger but i can't tell how many hours a day i spent. I only model these tanks in work whenever i have some spare time.
Now.
Time for the Soviet tanks:

KV-1 1941 variant (one of my recent ones - very accurate)

T-34/85

T-62

This post shows just my models of varios tanks. Straight up SU renders. Any comments welcome.
Starting with american tanks:

Ford 3 ton tank 1918

M4A4 Sherman (one of my first tanks, no blueprints used, wrong proportions, angles, dimensions...)

M1A1 Abrams

I'm just wondering why are the SP joints stretching. Can you get rid of that? Or maybe could this be set for each joint separately? This stretching is sometimes helpfull but when you try to do things like chain links or tank tracks it's very annoying.

this is wrong. the big wheels should turn when the middle gear isn't spinnig but its moving together with the motor joint (turning arond the wheels axis).

the big image is hotlinked from deviantart server and i'm going to let it be the way it is so that people can get hi res image without the fuss of following external links.

Here are some images of my Challenger II tank model.
Please leave your comments. This model can be easily found in the 3d warehouse. As well as my other ones.

i don't think so. i've a model of a tiger tank in the warehouse, it is 10mb and it shows shadows.

Ok. my latest one. It looks flat on the image in the 3d warehouse. It has shadows switched on and even the thumbnail of the file shows shadows. After uploading the model to the warehouse it desn't show shadows as you can see on this link http://sketchup.google.com/3dwarehouse/details?mid=6aceb5114485fb30a21328a4a54425f7
So what's wrong?

ok. i've seen models on the warehouse that have a motor with reverse function controlled by a single controller. |Still i cant figure out how to make such a motor. Please. Prepare a tutorial for me

I have a problem with styles i think when i export models to 3d warehouse. What i want to achieve is getting the image of my model displayed in the warehouse with shadows visible. But what happens is that i have the shadows switched on in my model, i upload it to the 3d warehouse and it shows without shadows. How to get it sorted???
