How To Design and Create Some 3D Engine Components Using AutoCAD?

[uba]

Could someone please teach me how to design and create a crankshaft (4-cylinders, inline, Otto engine), piston, and connecting rod using AutoCAD?

 

Thank you

I think you'd be better off doing this using Inventor. But, if you want to try doing it with AutoCAD start with the piston above. Tell us how you would start. We're all ears.

 

How much AutoCAD 3D experience do you have?

If you are new to AutoCAD, your request is very unrealistic. This is a very complicated piece of machinery and it would be a challenge for any seasoned 3D AutoCAD designer. If your request is legitimate for employment purposes then I suggest formal training for Inventor instead of AutoCAD. Hope this helps your understanding.

Yes, I would like to start immediately!

It's not too bad.

What drawings (2D) do you have to work off of?

 

Tell us how you would get started on the shaft shown in your image. What commands would you use? How would you go about creating the part?

I agree with Remark, a good set of plans to go off of will be key.

Pick one of these (it says in Inventor - but you can use any CAD program, including AutoCAD).

Start modeling and post back (with dwg file) exact information of any feature you are having trouble with.

Up to you now -

Designing a four cylinder engine sounds like a fun project. What would be the end result? If it is to have a viable, running prototype then perhaps I should say "a fun but insanely complex project".

 

 

Do you have a displacement and bore/stroke ratio in mind. I think that would be the first important decision.

Designing a four cylinder engine sounds like a fun project......

 

Might take a day or two though.

I guess I should ask, "What day is this assignment due?"

Boxer four, nice design. Shrink-wrap or full internals?

[JD Mather]

Full internals.

Full disclosure - I did not model the engine, got it from someone else.

[SEANT]

Full internals.

. . . .

 

 

Conceivably, all similar parts can be referenced, and a designer can take liberties with level of detail – still, that has to be taxing on a workstation. What is the application/model memory footprint when loaded as an assembly? Has hardware advanced enough for real time manipulation?

I think you guys just scared the OP away.

Certainly possible. You would think that anyone brave enough to even contemplate the task would be pretty fearless.

Well let's hope he is just off gathering the necessary information before tackling the project head on.
