Hello All--

I am working on creating some sanitary elbows and I am new to solidworks routing. My company use tube for the most part and we do not bend the tube. I tried using solidworks routing for tubes, but found it limited because I did not have the option to work with tube elbows separately. We weld the tube fittings to our tube assemblie. To do this I have jury rigged the piping portion of solidworks to accomadate the different tube and tube fittings. Then I changed the schedule property to wall thickness and the specification to weld grade of material. I am working on creating a tube butt weld elbow that is longer than a standard tube elbow (short elbow). This elbow has straight tangents on the end. I have not been able to get solidworks to recognize this geometry. Has anyone had any success with this type of fitting? Attached is the fitting I am attempting to use.

Note: the file attached has the tangents set to .001" because I would like to combine the short and long elbow configurations into the same file.

Thanks.

Correct Answer

So except for yours being with a groove and in Imperial and mine without a groove and in metric there's no real difference, correct ?

You mentioned that you hadn't been able to have SW recognize straight tangents on your elbow.

Now English isn't my first language, which is why I wanted clarification to make sure I understood you correctly.

As you can see in the following picture

It all boils down to where you place the Cpoints. On the end of the elbows, the end of the tangent lenghts or even inside of the tangent lengths, if you want socketweld instead of butt weld.

See the reply in context

Perhaps I don't understood you correctly but do you mean to create something like the following (see pic1)

if so then perhaps pic2 & pic 3 can help

We use victaulic elbow here and they have a tangent length to accomodate the groove. see screen shot.

I too am a bit confused by SW to recognize straight tangents...Please elaborate.

@ Peter yes they are the same.

Hey Tony,

Thanks for the reply. I was having trouble getting the elbow to properly connect to a route. I would import a solidworks elbow without extensions or tangents from the end points of the arc which would insert as expected. Then I would import my custom part with the long ends and it would not work correctly even with connection points on the ends. However, I notice that the elbow needs to be created only with a sweep.

yes. when i made mine i started with the default elbow and added the tangent ends.

Tony--

My goal is to use workgroup pdm to control all of the fittings. Is that a good idea or do I need to import every new routing component into the solidworks routing library?

i have never used WPDM to manage design library. its always been on the server accessible to all who use it. We now use EPDM which is a lot different and seems to work well.

Tony--

Do you just create the routing part, add the correct dimensions, c-points, and r-points then put it into enterprise pdm? Or do you use the routing library manager import tool then save it in a location within enterprise pdm for the routing manager to reference?

Sorry for all the questions. You and the other respondents have been a great help.
