Autocad Style ISO-Drawing (Updated in YafRay)

Here’s a quick render in progress. I am not aiming for photo realism or even scaled to size, but something presentable. This is a “Design-Build” blue print for a small construction job, meaning that there are no actual specs for the piping. In other words “connect the pipe between the equipment”. This is not an uncommon practice for some of those last minute side jobs.

This is an actual piping project, where stainless steel piping will be installed. Somebody from the job-site came up with a crappy pencil-drawing on a piece of paper, so I decided to make it my weekend project.

I have seen many AutoCad prints for job-sites, but none that have the quality of Blender. AutoCad’s purpose is to have accurate drawings and blue prints for construction, not to paint a pretty picture.

Anyhow, when it is finished, it will be very clear on what is needed to fabricate the piping. When I print it on paper, I’ll leave eatra space to allow for jotting down bits of information for pipe sizes and take-offs, gasket counts, bolt counts, etc…

Hi Spin.

I teach Tecnology. Mind if I use this as an example of how Open Source software can be used in real world contexts?

Sure You can use it! It is just a lot of repeated basic shapes.

I’ll post a few better renderings in a short while.


Hi Spin!
It looks good, from a technical standpoint.
From personal experience, I find that for a technical drawing (especially ones that actually have dimensions :stuck_out_tongue: ) that it is easiest to create the model in SolidWorks (really a fun program once you get the hang of it :slight_smile: ) and then importing it into Blender via VRML.
btw, where do you wander to if you want to get a job doing something like this? I play paintball so am always in desperate need of cash :stuck_out_tongue: .

A close up.

A little more detail than I originally planned on.

Notice that this “drawing” does not have any flex-pipe on the inlet and the outlet of the pump. Also, there are no instruments to measure pressure, temperature or flow. Mainly, look at this piping configuration. Kind of strange eh? It looks as though it pumps into itself, a never ending circulation. Here’s why. There is another identical pump 500 feet away with the same setup. One pump sends water to the tank, for storage, using a single underground pipe line. When water is needed at the other location (500 feet away) this pump sends it back. A person has to manually operate position the valves at both pumps to prevent both pumps from dead-heading each other.

Was this modeled entirely in Blender? I work for an engineering firm for oil/gas facilities (in Calgary AB), and I did a quick n dirty animation/fly through of a plant that was modeled in AutoCAD/CADWorx, then exported as 3DS, imported into Blender, then rendered out. Yours looks much nicer though. I just used the default acad layer colors for the objects because of a lack of time.

You guys look like you would know this, what file extention could I export from blender to be recgonized by inventer(or rinosarous, or autocad 2000i)? Or must i do somthing like to .3ds to .dwg?
BTW, very nice on the job pipes

*.obj does the trick, at least from ACAD 06 to blender.

I made a quick homer simpson type hand once and exported it as DXF, then brought it straight into Autocad 2002. not sure about 2000i or inventor.

Spin - what sort of light setup and yafray settings did you use? They look great. Also - the welds. Are they texture mapped to give the welded bumpy look? Incredible detail! What area do you live in?

That last rendering looks very real, except for the repeating floor pattern. I’d like to know your light setup, too.

You guys can have the BLEND file to tinker with, right here…

My YafRay settings:
I usually use Area Lamps with about 4 samples and Ray Tracing on. I make the “Panel” portion of the Area Lamps large, but make the distance short.

Xml button = off
Method = SjyDome
Quality = Low
Cache = on
World Color = White

Here’s a revised version of the pump. It is designed from an actual pump that is going to be used.

Great work on the welds and joins :smiley: :smiley: :smiley: :o :o :o :o

Thanks for the blend.

I don’t think I’m alone in thinking that your chrome technique should be added to the official textures library on Wiki, or

Simply Amazing.

I just applied a little Mirror effec to the piping. That’s all. But the main trick is to use all white skydome and add a few BLACK planes behind the camera to have the pipe reflect something.

Here’s one of the final updates. This project is actually over, but I still improve the Blender portion of it.


Hi Spin! Always like following your progress. Might want to look at this German site They make money from their Blender models :wink:
