SHOCK FORK design model 3

[CAD2015]

Hi,

I need to design a Suspension Shock Fork (please, see the attached picture).
It doesn't seem to be a easy design, but I count on your advise.
Has somebody designed a similar part in the past?
How should I create this model?
Do you have a model by any chance?

Thanks

What version of NX are you using?

I use NX 9.
Thanks for prompt reply.

Not sure if you can open Catia V5 CGR files.............

This looks rather morphed. Is it a scanned model ?

To me it seems one would use freeform modelling combined with sheet metal.
I'll give it a try.

RUGmechanic,
Thanks for reply.
Yes, it is a scanned model.
I have no idea about conversion of scan data to a CAD model so far.........

If you have the scanned data. You may want to look at this thread. Try doing a Rough offset with a distance of 0.

Could somebody show me how to design a part like the one shown in the two attached pictures?
Would the use of the Sheet Metal be possible in this case?

Thanks,

Well here's a start that should put you in the right direction.

Mr. Baker,

Thanks again for taking the time to reply to my thread.
The area you started with wouldn't create any problem for designing.
The real problem is the area below the welding zone (please see the attached picture).
How would you design this critical area? Can you start a model ( the dimension do not matter) similar to the pictures?

I also have attached a related stl file.
I have to learn how to create this part, I can't sleep until I'll got the lesson..................

Why are saying that you "...have to learn how to create this part..."? It sounds like this is some sort of a 'assignment', like perhaps as part of an academic program. Is that the case?

No.

The shape of the part is very challenging.
I have never designed something like that so far!
That's the object of my curiosity.
My current job assignments are totally different.

Here's another part file addressing the other end of the model. It's a bit messy (I could have done a slightly better job using NX 10.0) but it gives you the shape that you're looking for.

JB,
Can you help me understand the swept feature? I'm looking at your example in 10.0.2.6. Swept(17) use the 2 sections and Bridge Curve(15) as the only guide, but Bridge Curve(14) has a direct influence on the shape of Swept(17). Can you explain what's going on or am I just missing something?
Thanks,
John

Bridge Curve (14) is guide 1 and Bridge Curve (15) is guide 2; each guide string is made of one curve. The "Select Curve (1)" prompt is showing how many curves make up the selected guide, not how many guides have been specified for the swept. You may need to expand the "List" panes to see the whole story.

If you edit the swept and highlight "Section1", you will see that it is made of 6 curve objects; "Section2" is made of two curve objects.
