How are the 5 blades created on the centre.I cannot follow the model to work it out

1 blade was originally made, and then it was arrayed around the center axis to have 5.

[James__S]

I was hoping to see how the first blade was created

Thanking you

A search here should turn up many examples posted in the past.

I did a quick search and found this -

 Maybe that isn't the best link

Loft surface curves.

Trim the surface.

Thicken the surface.

Fillet the solid.

Pattern the solid.

Fillet the solid to the hub.

Attach your *.ipt attempt here.

It was probably designed thru a loft

[mdavis22569]

JDMathers link is a really good one with an example in it ..

[James__S]

Thanks

This would be also a good example....would you use the Loft ?

[mdavis22569]

I would ..but that's me ..

I don't recall whether I used Coil or Loft, but it would have been one or the other.

Attach your attempt here and that would motivate me to find my example.

[JDMather]

Are you making any progress in an attempt

[James__S]

This my attempt...plenty of improvement needed i am sure

Thanks

[James__S]

Any thoughts on improvements?

[JDMather]

What are your specifications?

Do you have a drawing that you are trying to reproduce as a model?

Do you have a physical part that you are trying to reproduce as a model?

Hi! I took a look at the original body and did a bit untrim operations (Extract Loop). The base faces creating the blades are quite simple. Please take a look atthe image and you should be able to figure out what to do next. Let me know if it works for you.

Thanks!

[James__S]

Hi

No drawings and no physical part.It is a learning exercise from a model i found of a propeller.

Thanks Johnson

Is there the file available for the .png you attached.Would be easier to work through and see how the steps were created

Thank you

James

Did it as a different solid on top of the original, hope it helps wont fillet though.

[James__S]
