Trouble finishing piping

[cpascual]

Okay so I am trying to model the internal dimensions of some piping, but I am currently having trouble completing the portrayal of the part. If you look at the picture you can see the skeleton of it. I tried using the loft command but wasn't getting the results I wanted. I tried using various extrudes but I couldn't get it either. The part has been tricky for me because I could model it easily if it was just a plain elbow but you can see from the picture that the top part meets at a point while the bottom part is more elbow like. Any suggestions or help would be greatly appreciated. Thanks.

Slice an elbow?

that slice command is cool an all but I still am not getting the correct results. I think it has to do with the part not having a constant diameter from the measurements I took. I am going to try to fidget with it now.

Could you not just draw a line that represents the curve and strait parts of the object you wish to create. Draw the circle to represent the size of the piping. 3dRotate the circle to the proper orientation put the center point of the circle on the end point of the line you created and extrude along a path?

No that ain't working. That is what I was basically trying to do from the start when I was using the loft command. But as you can see from this image that one side of the piping is elbow-like while the other side is more like a corner. What I am going to try to do now is make the corner side be more of a line than just a point, so hoefully this will work out.

I got it to work. I use the Slice command on a Torus and it created the exact elbow I needed at that point. Sweet thanks for the help guys.

Is this what you were trying to do?

Larger Size

I posted what I had to do. I know how to do a regular elbow for a pipe, but the one I was trying to do was not able to be done with the method you were explaining to me , just because I was having problems with the loft command. Doing it with a Torus and then slicing it allowed me to make the elbow I wanted.

Would it actually be made the way you have it shown in the weld shop though? I would think the fabrication guys could come up with something better.

[cpascual]

Luckily I don't have to worry about that in this case, but you're right, I imagine there must be some other way to do it, but I have yet to figure. At least the way I did it will suffice for now.

I'd like to think that as designers we do give some thought as to if the objects we design can actually be built the way we draw them. To not do so may cause delay along with a waste of time, resources and material down the road.

I would assume to get the same effect a fabricator would take 3 lengths of strait pipe figure the needed angels (if not already supplied) cut the middle leg with angles on both sides the the outer legs with corresponding angles on one side. That way when you can match the elongated opening on the pipe when cutting on an angle. Make the wields and be good to go. However you would not have the rounded outside edge it looks like you were going for. To be honest im not sure how you would match the pipe openings if you cut a standard elbow to the desired shape to make the sharp corner on the inside and maintain the rounded outside. If it didn't matter I guess you could try and fill the gap with wield.

Was this the result you were looking for? With curved Outside and Hard inside? I drew this in 2d to see the inside outside curve hard courner. I than drew the circles and revolved with a center point on the edge of the circle 45 degrees. This gave me my rounded outside with the hard line inside. I mirrored the solid and rotated to get the other joint than connected the strait piping. Was this the desired effect? Or am I still missing what you were trying to draw.
