Hi all,

I want to create a 3d elbow geometries of angle 90, 60, 45 in gambit 2.3.16. Please help me i doing this. I know it is pretty simple job but i am not able to do it.
It would be very nice if anyone can help me and guide the steps that should i follow to create it.

Thanks & Regards
Shubham Mishra

*create first cylinder as volume
*create second cylinder as volume
*move (rotate) second cylinder with desired angle
*move (translate) second cylinder with desire vector
*unite both volumes (boolean operation)

Thanks for prompt reply
As suggested by you, i had already tried it but i am not able to get the smooth bend at the joining face. I also attach the picture of it. Kindly suggest some more steps for it..
Thanks in advance

can you sketch what you are expecting in this case (90°)

[shubham208011]

ya its elbow with 90 degree bend angle

ah ok, I missed "bend angle"

Then you can use sweep function: draw the path for your geometry (chain of axis), create the source disk and sweep with edges

*create the source disk (cap cylinder)
*from its center (you need to create the center as vertice) sweep it with desire height (will be cylinder height)
*continue the path, by creating the arc (for example you can create 2 vertices, but there are other methods)
*finish the path by sweeping end's arc-vertice with desire cylinder height
*Once your path is generated you can sweep your disk with edge (maybe you need to merge the 3 edges)

while sweeping it, an ACIS error 73006 message: The chain to be sweept is parallel to the path..

what are you sweeping= vertice or surface?

[shubham208011]

Max find this picture

[-mAx-]

sweep surface with edge
If it failed: split your path in 3 portions: line, bend, line and sweep surface 3 times: one time with first line, second time with bend and finally with second line

[shubham208011]

no surface created while sweeping through bend...

ok then I understand sweeps along lines are ok.
Check your radius it seems to be quite small, that could be the reason

[shubham208011]

What radius are you talking about??
Bend radius or radius of cylinder?

[shubham208011]

What radius are you talking about?
Bend radius of radius of cylinder??

[-mAx-]

bend radius

[shubham208011]

I has increase the bend radius but it gives me same error..

*enable perpendicular option in sweep surface tool*Your bend radius has to be greater than cylinder radius else you have self-intersection problem
