Hello, I am trying to get this piece to overlap itself{aluminum Venting Pipe) and then try to unfold it using the flatten tool with sheet metal, but i am haveing a problem with it. Can someone have a look and tell me what i'm mdoing wrong.
Also i am looking at doing the same thing but using a spiral, the problem with that is I can extrude the spiral does anyone know where i could get the info to extrude a spiral.
Which way is beter for designing? ftp://24.42.130.192:21
Thanks
Hi Mike-
It looks like the inner and outer radii in the small jog are not concentric to each other. This will trip the program up with this sort of bend - i.e. when there is a closed loop and a Arc-Arc condition - the program does not know which profile to chase and since the inner & outer are not "parallell" then it gags. Alternately you might use a single profile open and use the base-flange insert, but in my opition, you have the better of the two methods started (model + sheet metal insert).
I made a change to the model and added the concentricity on the two inner&outer sets of radii and was able to get a viable sheet metal definition into the model.
Recently there was a question almost exactly like this one - check out the model and "how to" at:
This might help you (but no "how to" for this one, just blow by blow "rollback"):

Hey thanks for the help, I got the first pipe done with the equal radii, but I still can't figure out the spiral part. How can I make a spiral to extrude. I been trying every thing to do this but still I am having no success with it. even if I get this to work what is the better way to create the pipe. once I do get the spiral to extrude can I get the dimension to read it as the original circle. eg. if the spiral was made from a 3" circle can I still get that dim once the spiral has been created and extruded.
Hi Mike,
Are you wanting to make a version similar to the pipe (shown above) but without the little jog at the end? I.e. the same thing but with a smoooth transition?
I think this is what you are after (your other post indicated this possibly).
If so, I think we will need something similar, but whatever the sizes, we will need one arc and a slightly larger arc that is "thickness+cheating" larger than the base arc. Where you would transition from the small to the large is a judgement call - I would break-off the main arc 90 degrees from the "top".
If this is the case, we can make anther sample if it helps.
Regards,
SMA
