3D model/render work on the 2.2T motor I'm building
Originally I had all of this sprinkled throughout my engine build thread. Since it's somewhat of a budget build I get time to get up close and personal with each of these parts as I'm cleaning and inspecting and saving for parts and machine work.

To answer a few questions off the bat. Software: I use Creo 3.0 (the software previously known as Pro/Engineer) for 100% of the model work. The nice rendered images are created in another software called Keyshot. Using Keyshot I can bring in the model files and assign colors, textures, change lighting, backgrounds, etc.

You'll notice that in a lot of these the color/finish of the individual parts isn't exact. Each time I add to the model I make a new render file, and then I reassign colors to each part all over again. Because of this, I don't spend a ton of time honing the colors down. Once it's complete I'll get everything so that they look right but for now it's just WIP eye candy.

I don't update this thread with every new part I make, to see everything in the most up-to-date fashion visit my Instagram

Hope you all enjoy!

Gotta start somewhere.

started working on the cam housings

Optimusglen 09-22-2017 08:42 PM

cam covers coming along nicely

Optimusglen 09-22-2017 08:43 PM

Had an open evening, so more progress, adding parts one by one.

Beautiful !

I spend most of my work day using ArchiCAD to design & 3D model buildings... what you are doing is a whole 'nother deal. Seriously impressive CAD/3D modeling skills... I dig it.

Really great work. Are you scanning the parts?

Optimusglen 09-23-2017 08:38 AM

No shortcuts (scanning) I measure and create each feature.

3Ddesigns911 09-23-2017 09:34 AM

Nice work man.How far are you going to take it? BTW what engine is this exactly?

Optimusglen 09-23-2017 09:52 AM

Thanks! I'll be doing the full carburated engine. It's a 911/07 from a '71 911T

I might do a quick and dirty trans, but just so I can put it all in a 914/6 GT 3D model I have.

Wow. Lots of work there.

I can appreciate what you are doing because I started my case project by scanning a case at 50 microns and then modifying it to create the model for our casting.

Nice job.

Optimusglen 09-23-2017 10:26 AM

I do wish I could scan the case, I've been dreading that part.

3Ddesigns911 09-23-2017 11:18 AM

There has to be some scans or other 3D models that you can start with out there. It'd be pretty hard to get it accurately just by measuring.

My case model cost me $100,000 to give you an idea. It wasn't just scanning, it was the reverse engineering and the measurements, which are still ongoing. The scan and the point cloud just gave us a basic shape.

However, my model needed to be good enough to build off of, it is not a simple exercise in art. Dimensionally, it is perfect. But it was just a starting point for us.

I think you'll be able to simulate the exterior of the case pretty well based on your work you showed here. It doesn't need to be perfectly one will ever be able to tell.

Nothing out there for the case, realistically I would prefer to do it myself so that I can ensure the case model is done to the same standard as the rest of it. Plus, native Creo models are far superior to mesh, 3dsMax, or stl model files.

I know it doesn't need to be 100% correct, I'm not building casts for any of this. It is likely that I'll be 3d printing a scale version.

3Ddesigns911 09-23-2017 01:10 PM

What I meant was if you had something to start with as a "template" then you could create your own model based on that while verifying dimensions.

Spenny_b 09-23-2017 03:30 PM

They. Are. Stunning!

Seriously impressed, not only the quality of the images but also your patience. I wish I had an attention span longer than

Optimusglen 09-24-2017 07:15 AM

Thank you!

More progress.

Catorce 09-24-2017 08:53 AM

Amazing. I can somewhat use Solidworks - how is the software you are using different? Is it supposed to be for the same kinds of tasks???

Optimusglen 09-24-2017 09:11 AM

Yes, Creo is previously known as Pro/Engineer. It is an engineering modeling/drafting software. It does the same tasks as Solidworks. I do use Solidworks as well, usually only when one of our vendors sends us native SW files though, I prefer Creo.

Which is better is a highly debated topic with "fan-boys" on both sides of the fence. Solidworks is easier to pick up for beginners, but in my opinion Creo has more functionality. The same geometry can be created with either program, the methods are just different.

The models are created in Creo. These models could be machined, 3D printed, or with some redesign they could be plastic injection molded. Currently I've just been exporting the models to another software Keyshot which is just a rendering software. It takes the models in and I can assign colors, finishes, etc and render fancy images in high resolution.
