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?

@tig said:

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:
TestPart

@tig said:

But how would you determine the individual part's material and density/weight ?
You need the composite of several CofGs to do that - since a very heavy part will change the CofG in the combined assembly.

Yeah, now I understand.

@unknownuser said:

If all of the parts use the same material, then you just need to make a single 'group' of all of them, and then create one CofG of that one object. That way you can 'group' parts with the same material, get their containers' CofGs, and then combine those into a 'Combined CofG' - properly reflecting the weight-distribution...

Just tried it, and it worked like a charm. Thank you.

One more question about accuracy. Bigger value means more accuracy or vice versa?

@tig said:

You can do that already.
It's part of the toolset.
Obviously to tidy up later you'll need to put the individual CofG on their own OFF layer.
See th usage in the PluginStore 'Overview' for making 'Composites'...
sketchucation.com/pluginstore?pln=CofG

Sorry for my English, I described idea not well enough. As for now, when you determine CoG of complex unit which consists of many parts, you need to define CoG of each part and then compose them. It's working ok, if there are not many parts.

My suggestion is to make possible such workflow:
Select all parts of a complex unit and define composite CoG (of complex unit) at once.

In my example there was over 30+ parts. And it was quite hard to define composite CoG.

Hello, TIG.

At first I want to say thanks for such great plugin. I hope some day SketchUP will be powerful engineering tool as SolidWorks .

I have a small suggestion, when you working with a few components it's not a problem to define CoG of each and then compose them. But when there are lots of components it's quite difficult to make compose for all of them and do not miss some parts. Here an example of heavy model with cloud of CoG points:

Maybe there is a way to make it automatic for bunch of parts, like this:
Step 1. Select range of components/groups;
Step 2. Define CoG of each and then automatic add composite CoG.

Hope I described idea well enough .

Hi, Juan. Maybe this will help you: http://sketchupvraymaterials.blogspot.com/2012/12/z-design-materials.html #1 looks smart enough

What a great tool. I love the ability to focus in on an item and blur out the rest. I pulled up an old model of a small sortation facility and played around. I loved the results.

Hi, Mark. Very nice. What is it? Some part of automatic assembling line?

Hello Ken.

As an engineer I like your industrial buildings for Sim-City, they look very accurate and have nice balance of details. Did you use some references for them?

@allanx said:

Another great one Max...Love the style

Thank you, Allan.

@unearthed said:

Nice Max, you've even got a gardener watering the lawn! Not often that engineering drawings contain even a little humor.

Thx, Nigel. Such small "easter eggs" make drawings look more lively .

Small info:

@unknownuser said:

The individual processing units described above are part of the process-unit side of a refinery complex. They are usually considered the most important features, but the functioning of the off-site facilities are often as critical as the process units themselves. Off-sites consist of tankage, flare systems, utilities, and environmental treatment units.

@andre51 said:

Very cool models - was the shading done with SU materials?

Andre

Thank you. Render done in VRay and all images (render, line work) were composed in Photoshop.

@allanx said:

Nice, love the render with overlayed with linework...

allanx

Thx, it's my favourite style .

@tadema said:

Very nice modeling

Thank you, John.

Hi, my name is Max and I'm reading this forum for a long time. But at last I decided to put some of my old stuff here to show you . So here is my diploma project for chemical engineering master degree. I modelled it back in 2011 year and now after 2 years of work at chemical engineering company I see a lot of mistakes:

cyclone

A fluidized bed dryer

blower

air filter

steam heater

Sector feeder (don't know exactly translation)

Screw doser

All apparatus were modelled looking on photos and some info from books. The main PFD drawing were printed on A1 glossy photo paper with 300 DPI.

Click for a full picture:



All this apparatus pictures I needed for a mimic panel app (my friend wrote it special for us) when you click any of them a window appears with an info about an equipment:

So that's how I used SketchUp Sorry for bad english.
Thank you.
