reviving an old thread about VSS

[moner]

i am newbie to this forum, even though i have lurked for a couple of years. So, to everyone finally, hello!


down to business! Iam trying to create a part using the VSS. now, i have never really used the variable section sweep command before and i need some help since i am running into some trouble.


while trying to figure out my problem, i found this article:

which of course leads me to this thread...


[url]http://www.proecentral.com/portal/forum/msgDetail.asp?msg_id =2538&for_id=34[/url]


with these 2 articles in tow, i am still unable to create what i need. i need to create an inlet for an air conditioning filter. so, i need this piece to start as a square, and eventually run into a 4 1/2 inch diameter neck fortubing. basically, the 2nd article is virually a perfect model of what i need, but am unable to get it to work.


i think my problem is in my initial steps to create the model. argh!!!!!!

1. As the article says you don't need a VSS for this aparallel blend is enough.


For that this is a step by step procedure and it's also a unbendable part, if you're interesting in making it from a sheet of steel.

2. But I see in that article that a VSS could also be used, that makes me curious, I never used VSS for making a blend from square to circle.

there was another topic here about someone that had a blended wing section they wanted some surfacing done on. Whoever handled that response did some fine VSS work...have to see if I can find that back..

cheers,

moner,


is it all twisted around?..... if so you need to sync your start points


just what happens when you try?

 

[moner]

are both ends of the transitions drawn as sketches first? should i create one side (the square side) as aflat protrusion first?


my problem lies in the infamiliraity with the VSS step-by-step protocol. and it isnt like thedashboard is so clear.

moner,

how do you like that vss sandwich now?

sometimes a hint is all a person needs, hope the datum curves gave you some ideas. I also tried shifting the datum plane so the hex shape was on the other side...makes a crazy shape...

cheers,

M
