Hey there! At first Happy new year and Merry Xmass (orthodox) . Don't know why there are no post any more here for a long time, so here is example of outstanding work of KaranaK in SketchUP, more then 100m of polygons (there were some of his works earlier is this topic):

Horizon space station

Horizon Orbital is one of the first - and remains one of the largest - fully self-sufficient orbital installations. Designed before the spread of the standardized station projects, in the early expansion era when each station was an individual project and a massive undertaking, it was laid down in 2157. Seen at the time as both a symbol of mankind's newfound aspirations and - in a much more pragmatic sense - a significant investment in attempts to shorten the supply lines and centralize logistics, the project proved immensely successful, and a lot of later large-scale zero-g construction projects took their quest from the Horizon. Built with modularity in mind, the station has seen constant extensions and extensive reworks. The shipyard and manufacturing arms were added in 2225, making the Horizon the biggest and longest serving space station in the history.

Very cool! I like industrial thematic, but where is heat insulation ?

Hello.
I think many of us have often heard that SketchUP is not a serious 3D software, because they saw just some simple models. My small idea is to add a splash screen with most impressive SketchUP modelling examples from this thread: http://sketchucation.com/forums/viewtopic.php?f=81%26amp;t=33509 . Many software products use this kind of approach and this is good inspiration for newbies.

Thank you, guys, for the kind words .

Hi eidam655, so are there some news about sample pictures?

Hello. Here is another engineering work in SketchUP: Unit for liquid catalyst preparation:

hm, it seems my access to the old server got taken down (or my files have).

i'll try to find the images somewhere in my backups... however, all of these were for vray 1.49 and the question is how relevant they still are.

but as i said, i'll try to find them, just in case the were.

Hi eidam655, are there any chances that you have found images from the first message?

When you say 'merged', do you mean that you have exploded the various parts into a single container and then ensured that the container is now a 'solid' ?

Under "merged" I meant - group all separate solids in one group, that was my mistake. Now, I made one solid from all parts and CoGs are now almost identical in both cases (separate solids and one big solid). Thank you for your patience.

I made a test with my base frame. All parts are solids, with density 7800 kg/m3. Accuracy for both tests is = 1.

For the first one, I've determined CoG for each part separatly and then compose them. Results are looking true.

For the second I've merged all parts in a group and determined CoG, the result is to much high.

Where is my mistake?

Here is the test model:
