Add Pipe to Shell

[zendik]

Hello, This is my first post. I have worked in fabrication and have recently received the opportunity to move into design. My ideas have been good enough and now I have to learn how to convey them to the design people. So I am very new and have to learn this on my own, well almost, not on company time...I work for a BioFuels equiptment manufacturer...

I have learned the basics but I am stuck on something. I need to design a shell 31" diameter, 95" tall, with 2 3/4 threaded pipes evenly spaced on the top of the tank, and the tank needs to be domed top and bottom. I am able to create the tank as a shell, create another part for the dome top...but I cannot get the pipes to mate on the dome. i have tried making holes and inserting the pipes but it is not very elegant.. Any ideas or direction would be soo much appreciated.. thank you in advance for any wisdom

Zendik,


It would be good if you could post a pic of what you're trying to do so we can see excatly what you're doing. Quite often, it's hard to visualise with words alone.


In the domes part, you could add reference geometry in the form of axes. These axes would be the placed where you want the centre-line of the pipes should be. You can then use these axes in the assembly to assemble your pipes rather than having holes. Adding additional geometry is essential when it comes to placing and assembling components correctly and for creating features and so it would be worthwhile teaching yourself about it.


There is so much to learn with 3D CAD that you will never stop learning, which I think is one of the things that makes it so enjoyable. Best of luck with it.


Hope this helped. If it didn't come back and ask again and I will try and help.

I don't understand very well your problem (maybe my english is not good enough), but an advice: Try to model the real situation.


Good luck !

Thanks so much for the rpely and suggestions. I will spend the day learning about axes and then get back to you...I am trying to upload a picture of a homebuilt processor that we want to model and then redesign...hmm, I keep getting error trying to upload the image..

Well, imagine... a tank. 31" in diameter, and 90 inches tall, with a slight domed lid of about 3" rise in center, similar to a household well water pressure tank. The 3/4" steel pipe is welded or threaded on to the top about 20" from center on both sides..

Send me the SWfiles maybe I can help you [email protected]

I havent yet gotten that far to have any sw file. I have been experiementing with how to accomplish this.. does my last post make sense enough. I am studying the reference geometry and the axes but it is confusing so far

Design the parts all in context and uncheck the merge parts list when you create the pipes.

Make sure you have multiple bodies for everything that you will need seperate.

then INsert - features- save bodies create a folder and type the name of your assembly there. Select the bodies to be split and re- assembled then hit ok.

Should be easier to build the pipes in context.

to flush the end of teh pipes out extrude up to surface and pick teh inside or upper dome to end teh extrusion, or offset a surface 0 inches and use that as a surface to "cut with surface" to flush up teh end of your pipes on the water heater side.

thank you very much for you rsuggestion., I will give that a shot tonight.. thanks
