Radiuses on "Y" manifold

Radiuses on "Y" manifold

Radiuses on "Y" manifold

(OP)
Ho Ho Ho And a Merry Merry Xmas, Gentle Men and Anna.I am having a problem applying radiuses at the intersection of the straight tube and the "Y". Both on the inside and outside.Any help?SWX0011

RE: Radiuses on "Y" manifold

I can probably help you if you put up a file I can read. SolidWorks is not interoperable with itself, so a neutral file format like STEP or IGES will allow everyone to see the problem.

RE: Radiuses on "Y" manifold

Anna I was looking for about .5" R. for the outside, and for the inside, i'm not shure. But if I can get anything to work, I can then get to the flow and volume ect. dialed in.

RE: Radiuses on "Y" manifold

Do you think you guys could post the SolidWorks files?  Step files do not do much for seeing your modeling technique.

I would like to see the feature tree in your parts to see what you are actually doing to solve the OP issues.  I suspect I could learn something.

Cheers,

Are you running TOOLS/CHECK on the part? Do you have Verification on Rebuild turned on in TOOLS/OPTIONS/SYSTEM/PERFORMANCE? The previous version and this version had problems importing into SWX 2009. That last one looked like this:

I got your step file to come in by turning off the BREP mapping in IMPORT options and then using IMPORT DIAGNOSTICS to fix the errors starting from the bottom. The only real problem was the filleting produced general faults so I couldn't see what you did for the fillets.

RE: Radiuses on "Y" manifold

(OP)
Gentle Men I agree with Anna!! I am having problems in SolidWorks and would appreciate if you could show the steps taken so I can try out the steps and radius how and what I want to radius, A big mistake is radiusing the sharp split a the end. That needs to be a sharp divide.I am sorry that I didn't model in the version of solidworks you are using, But if you tell me what version you need, I can probibly model it for you. I have Ver 7 on an old machine here, that i can use to model manifold if it would help you. But I would be ideal if I could see how you are applying radiuses. There probibly will be changes made to the basic configuration of the manifold, as I progess, getting the best air flow for the application. Merry Christmas and a Happy New Year!!!

RE: Radiuses on "Y" manifold

Oops,
I didn't check the quality on import - I'll try some different settings when I get a chance.

For the last time read the FAQ! You can't learn what you need to learn from the SW file. This technique has been explained before in other threads. It has been around for years. There is no substitute for studying the information given in the FAQ. The FAQ leads to a download of a presentation that includes, I believe the SW files you need.

Also just a little trivia...
more than one radius is radii, not radiuses.

kellnerp,

I wholeheartedly disagree. Given the actual SW files a user can step through the tree and see how the features were generated, change values to see the affect and understand exactly what is happening in geometry whose original structure is something they understand, after all, it is something they created initially. The FAQ you pointed to does basically the same thing, in essence combining the help files, and handful of tips, and the real world examples into a single location. Also, in reviewing the FAQ, it appears that several of the documents are out of date, referencing material as far back as SW 2005 or older. While we don't know what version OP is using, I was able to open it in SW2011 without an old version file warning. Things have change quite a bit since the original tutorials were written and learning from a model done in his currently version will only benefit the OP.

You are drifting off topic. The thread is about filleting difficult geometry. The FAQ discusses a principal that transcends releases. You can't see principals in the feature tree.

So my posting the 2009 sldprt file here obviously won't be any more help than the dumb solid to the filleting problem. Thank you for making my case for me for interoperability. And since you can open his file and give him the technique why don't you do that and show him the complete feature tree?
And if the OP was so inclined to post a dumb solid as a step file as I originally asked I might be more inclined to post an sldprt file.

RE: Radiuses on "Y" manifold

ArtL,

Forgive the delay, I have started working with the model but unfortunately was dragged on to other projects. I will post a solution for you as soon as I have time to button things up to my satisfaction. To at least give you an idea of the direction I am looking at though, based on your request, I would recommend looking at restructuring the guide curves that drive the lofts to get the fillet you are looking for. It's a bit of a pain at this point to completely rework the geometry, but not impossible. I will post the finished file when I am complete.

Kellnerp,

While you can't see principles in the feature tree it is possible to see and understand concepts by working with them. And posting a 2009 file would serve a reasonable purpose as the primary differences between 2009 and 2011 was the addition of a handful of features and UI changes. The same cannot be said for 2001, 2003, or 2005. I am all for interoperability, but the software isn't going to support it between versions any time soon, in part because changes from version to version don't track well when going backwards. New features added in versions simply don't have an analogous component in old versions. I'm sorry if you feel that I was stepping on your toes when I was simply trying to offer you a perspective on why OP was hoping for your SW file. Being bitter because somebody offers a different viewpoint doesn't help anybody.

Not in this case. The key concept to successfully filleting this is invisible, hasn't changed since 2003, maybe earlier and has nothing to do with guide curves or new releases.
I am frustrated because I simply asked for a dumb solid so I could see what he was trying to do and have yet to get one exported from SWx. I am trying to help the guy, was the first one to jump on the problem and just can't seem to get any cooperation even from the OP in trying to help him.

If the OP can't put up a parasolid v19.1 or earlier maybe you could. I'll update the FAQ with it. Thank you.

I've done this type of geometry many times in my 15 years of using SWx. I keep up on current releases of SWx but choose to remain with 2009 for performance reasons.

RE: Radiuses on "Y" manifold

I got the parasolid from your original file ArtL. The attached parasolid has the fillet in it that you needed using the technique in the FAQ called atomic bomb of fillets.

This model has serious lofting problems. I would address that in another thread. It will not round trip in IGES or STEP and would likely cause CFD, FEA or CAM problems.

The lofts from the nozzles to the neck would make a good user group presentation.

RE: Radiuses on "Y" manifold

(OP)
Kellnerp  Thanx!! I will look at the parasolid as soon as I can. I'm sorry for all the problems I have caused you. I am a semi-retired tool maker by trade, and have used solidworks since 1998,but only part time,because tooling, jigs and fixtures is my main money maker.This is a part for a friend, I do design off and on. So my expertese in solidworks probibly is not up to par with a 100% daily user. The use of other programs is basically non-existant.So I have been confused about parasolids,Sat Ect... The lofts are really the only way I could get the "Y" to work. Any help would be apprecialed. Respectfully  Art L.

Start a new thread for that. This thread has too much extraneous jibber jabber. :)

A loft like that is not easy. Grown men have been made to cry.
