TurboCAD Drawing: Radial Engine w/ Progression samples

Bob,
I probably could, but it would *not* look like a Radial Engine --- LOL Even the Author of the project said that he had to "think through" the problem for a while before he started to see how to approach such a task. A lot of it is really based on 2D modeling first. About 80% of everything is a "revolved" 2D surface. However, a lot of pre thinking I am sure went into this. I like the fact that the author told me how to make edge outlines to look and act just like Solid Works with just two check marks done in the rendering is all you need.
Also, I might add that for my machine and the authors machine, it takes 3 1/2 minutes for the full 3D (with materials) to render completely.

In order to speed this up, a person would have to invest in the Quadro 4000 or up line of GPUs - that alone is about $1800

I just built a Coffee Lake CPU machine for $1700 including the monitor. The Coffee Lake Intel i7 chip has 6 cores instead of 4. It's fast, really fast. The base clock rate is 3.7 gigahertz but you can overclock it to more than 4 gigahertz. It uses DDR4 memory and the motherboard I chose, a gaming board by Gigabyte can handle twin GPU boards in SLI or Crossfire configuration. I'll bet it can render those drawings fast. it can do full 4K video games at 60 frames per second. I installed Mac OS X High Sierra on the machine and it flies!

I've always gone for custom made computers because it's cheaper and you can get the exact hardware you need for the type of work you do. Building a computer is a lot easier than building a model ship. It's all modular so parts are easily interchangeable.

Anyway, I know exactly what you mean about the 2D modeling. Fusion 360 is based around 2D drawings that are then used to create 3D object and about combining those objects to create larger 3D parts. Once you grasp the concept of breaking things down into smaller 2D drawings, it becomes a lot easier to approach a complex 3D object.

Thanks for sharing your drawings and thoughts on creating it.

Hey Bob, WOW - I bet that IS fast !!!
thanks for sharing your computer build - this is great as it allows for a learning in what components are needed to have a good machine to do the 3D stuff with.

I am not ready to say by a long stretch that I am good at 3D. I am ready to say that I have learned a lot from sticking with it.

ps. Oh, I assume that you are using a separate video card ?
 
some cad users will draw 1 to 1 or full size right now I am drawing a steam engine and if I did it full size my drawing is 14 feet X 7 feet moving around the drawing it takes time for the drawing to regenerate but if I do the drawing of say 1 inch = 1 foot the size of the drawing is greatly reduced and regeneration or rendering is almost instant and most any computer can handle the drawing.
When I do drawings for model work or for laser cutting I do the drawings in the scale of the model.
 
I always draw 1:1 but I also have 16 gig ram and Solidworks goes into large assy mode when I get over 500 pieces or whatever I set it at. when it is at LGM mode then it only shows a visual so system memory not used and when you edit a part it then loads that part

I know a lot of people run dual processors and dual graphix cards for their uber cad computers
