Hi.

Since all the times I needed to do something particular I never remembered what instruction (blend, sweep, blend with sweep etc.) was more suitable to solve a specific problem regarding surfaces, even because I don't open them very often, I did these example files.
At this point I ask you if you give us a look to verify that the methods used are the most correct, and if you have other examples that may be useful are welcome. I hope to do what you like to make these jobs available.

greetings

in general I think for these figures, everything ok, nothing to say.

on the helical sweeps, personally the springs the starting point variable from the beginning and the height at rest I manage with the plans, reasons:
- compression springs have in 99% of cases at least the first 2 coils per package side.
- together are the classic flexible components and is much easier to assemble with the plans
 
Missing the boundary blend seems to me. I have a bit of surface modeling experience and it is definitely the most versatile feature and that the only one that allows to create patches between surfaces.
 
I loaded the spring here.
the 3d is simplified, in the sense that the sweep is a variable type, in reality should be made three distinct sweeps for this type of spring (an initial and an identical ending with coils to parcel and a central for active turns), because the variability understood from pro-e/creo, does not allow to arrive to the completion of the last spire (or stops before).
the trajectory and the steps are all parameterized, so to change it just intervene on the parameters.

can be inserted as flexible managing the upper floor from the wf4 onwards.

n.b. if it fails after assembly one of the 2 cutting features (it happens in creo 3.0), it is enough to remake both and the problem does not come back.

the spring inserted does exactly my case.
sin that with creo 2 there is no longer the command protruding.
Hi.
 
Hi.
320 js spring is as I mean it but in creo2 there is no command: protruding
Thank you.
 
But if you do three sweeps, then you do more with flexibility unless you can join?? and then there is the stretch of joint to edge
Let me know if you know the way to combine the three sweeps.
Thank you.
 
I didn't create 2, but it seems strange that the protruding command disappeared.
There's not even the chart anymore.
However, it seems to me that in order to do an exact job you have to do three sweeps and then use the central one to vary the flexibility otherwise the pace of constant turns is wrong.

with flexibility is not a problem (the longest to do yes, and the worse you have), but the important thing is to parameterize and shape the whole with 1 reference to be controlled with flexibility, in my case, I used the upper and lower support plans of the spring.

to make the 3 joint sweeps, you could also do with the surface offset function "with replacement" and use a plan that represents the end of the sweep, but it is more complicated and requires additional calculations to be made for the program in case of flexibility, so the precise function of the spring in the set is well weighted.
 
Hi.
I'd be grateful.
Thank you.

Hi.
Sorry there is someone who with creo2 or creo3 manages to make the spring made by 320i s with wf3. it would be useful to understand how to use the table they entered.
Thank you.
Hi.
