Fair enough, good luck with your part.

I thought i would throw this question out there 1 more time to see if anyone does have a solution for taking less steps (6 loft cuts) to make the fins.The final result is what i wanted so possibly it can only be done this way

If you were to actually create this part in the real world, how would you go about creating it, IE: what manufacturing techniques would you employ?

Hi Trumpy81

 

Only going to use for a presentation.Looking for the quickest way of modelling.Instead of using 6 Lofts i was hoping 1 Loft and maybe a pattern feature.Just looking at my model it is quite possible that to get the desired shape i actually need to perform the 6 Lofts.I will model other pumps in the future so looking ffor quickest technique

 

Thanks again

If you are going to present this, don't you think it should at least represent a manufacturable part?

 

The way you are modelling it at present would prove impossible to produce at a reasonable cost. That's why I suggested a revolve cut, the quickest method I can think of, to make the angled fins, and if you look carefully at the lofted fin ends, they pretty much follow the same profile as you get from the revolve cut. It is not as pronounced and the edges are a little more inline but otherwise it's the same effect.

 

Something else to consider, is the root of each fin where it joins the circular body of the part, this area, at present, could not be cut. It could be cast, but I would still advise using a fillet in that area for strength of the fins. If the part were to be cast, then again, you need to include what is called 'draft' to the fins to make the whole part removable from the mold.

 

If it were to be machined, then you have to consider the cutting tools that would be used.

 

You can spend a lot of time and effort modelling a part just the way you want it, but if you don't make the part manufacturable then what is the point of all your time and effort?

 

If you are going to present this model to anyone, you should at least consider these facts and include them in your model. I'm sure I would not be the only one to recognise the deficencies of your current design.

This part is not going to be manufacturered,cast,cut  etc..etc...I have been asked to make a model of a machine which has this pump and they then will use it to show there machine ffor training purposes.I will add the fillet when i get to that stage.I am simply just trying to replicate a pump for demonstration not manufacturing.I was also using learning techniques as well so i tried to replicate the pump as accurate as i could with the least amount of steps

 

Thanks

In that case, do you have access to this part, so that you can take measurements?
