Helical Spiral in a circle shape

[Sarah-louise]

Hi there,


I am trying to add a spiral that has its ends joining together to create a circle. I would like to add the spiral so that each wind is fed through one of the 70 holes in the lip of the metal plate below. It is actually a part of a plunger coffee jug that I am attempting to model, if that helps you get your head around what I am trying to do. I have been using proeng for only a couple of days so my knowledge is very limited. Any help would be greatly appreciated. I have had a look at a post a few days ago about a helical sprial in the shape of a question mark, but unfortunately I did not understand what they were saying.


Thanks so much

Have a look at the "Super Sweep" file in the Files > Other > Odds and Ends > Odds, Super Sweep section of this site.

Cheers,

Thats a cool model

, but it uses the "old style " of Variable section sweep. (pro/E forces you to look at the old menu manager , the model is probably made in pro/E2001 or earlier)


in my model i use the "new style" of VSS, hopefully it

tobbo is correctin his description. If need be, I can send a model of what you are looking for in WF 3.0

Hey,


Yeah if you wouldnt mind sending thru the model that would be great. Im using WF 4.0, does that make much of a difference?

Here you go!!

, take a look at this simple spring . In "spring_dia" feature (VSS)...if you look in the sketch, and then look at the relation (tools - relation) you will se " sd6=trajpar*360*7 " . This means that the dimension "sd6" (seem to be zero when you look at the sketch) is actually the dimenasion on the angle on the line that sweeps. (in my pic below sd6 is the same as sd=8 just two different models so dont get confused,

) And 360*7 menas that it will "rotate" 7 times along the sweep curve.

(or, look at my other model in the other post.)


There is no difference in this between WF3 and WF4

Wow!!! Tobbo thanks so much! The clear instructions were brilliant

. So Ive got this far...





now I just want to increase thespring's thickness. Ive had a fiddle but I cant seem to make it work. Any expert advice??

Hi, I have only wf2 so I can only see what you have done on your images.


It looks like you made a surface by sweeping a line.


With that vss as reference, make another vss and sweep a circle as a solid.
I think that will give you what you are looking for.

Couldnt help playing with the relations a bit, sorry for spamming
