Piping branch connection

Hi you should probably look at how these would be manufactured. I doubt that a hole will be drilled in the side to create a branch and the end of the pipe scalloped out. It's far more likely that there will be branch tee fittings and clean normal cuts on the pipework. You should model up branch tees and add ports to allow them to be aligned properly.

Hi Anand,

In your example, did you have your pipes "solidified"? also, what version of Creo are you using?

I ask because I just ran a test using Creo 3 M110.

Here is an image of my pipes "before solidification" - it looks much like yours did:

I then did a quick "Pipe Solid" to solidify my pipelines into solid geometry...

Looking closer...

When I change my view to be "hidden lines" - I get the following:

Similarly... my new "pipe solid PRT model" looks like this:

Please let me know if this is not the case on your end - I'd be more than happy to help debug.

Thanks,

Hopefully I have some big news here. I mentioned this thread to my counter part at another business unit, and he said his system copes the pipes. We are running off of the same settings, so we did some digging to figure out it. This might not be an all-inclusive solution, but we found a way to make it work every time for us, and ways that it does not work for us.

Just to tease the point, here are the ways it doesn't work first:

1. Using sketches to define both pipelines. There is no trimming done on the 2nd pipe or hole in the first.
2. Extruding first pipeline. Adding a datum point to it (offset from the end) to locate your second pipe, and then extruding from there. There is no trimming done on the 2nd pipe or hole in the first.

A VERY slight modification to either method is what we found works every time (for us). Create your first pipe in whatever means you find best. Doesn't matter if it is following a sketch, extruded, etc. Where you want your second pipe, Insert a straight break component (we used a tee). Doesn't matter what one, what the size is, or anything. Delete the fitting (notice it also deletes the pipe joint but leaves the datum point.) Use this datum point as the start point for your 2nd pipe.

Our only explanation is that the datum point is then associated with the pipe extrude, instead of just the pipe end, but this still seems crazy to me. Either way, it works!

Spec driven could also make the difference.

James, how are you creating your pipe segments? Would you mind testing it in one of the manors that I said didn't work (without using specs either) to see if we can replicate it?

Thank you!
