Tube pipe bending
Hi FreeCAD Family,
I have a project. This project is Tube Pipe Bending. When a value is entered in the x y z parameter then pipe will be draw it.
x parameter draws the pipe
y parameter is rotation. this parameter is very importing thing thah is turn all the pipes drawn up to now.
z parameter is bending. I need this programa macros ?
the other parameters is
radius:
pipe diameter:
can you help me this project ?

Re: Tube pipe bending
Hello mesutbarut, welcome to the FreeCAD forum.
I did not use it myself, but there is an addon tool, the flamingo workbench, which is used for piping stuff.

Re: Tube pipe bending
Hello mesutbarut,
Welcome to the forum.
What mesutbarut describes is a typical program (more like a simple table actually) to bend a tube using a multiple-axis tube bender.

FreeCAD does not allow you to create a bent tube from a tube bending program (surely a python macro could be done). You will have to manually draw or sketch the tubing path, add the tube profile to one end of the path, preferably centered; then create a sweep to generate a 3D solid, and finally void the solid to get a tube.
If all your bends share the same radius, you can do this pretty easily with a Draft Wire (DWire). A DWire can have coordinates in 3D, and it has a property to round the corners.
I made a video about it a long time ago:
Unfortunately, you need to know in advance the lengths of the theoretical intersections of each corners without the bends, which would require some calculation if bends are not 90 degrees. So it might be easier to use a series of sketches instead.
If you can give me a sample of values for one bent tube, I could demonstrate with an example file.
Welcome to the forum.
Piping has nothing to do with tube bending. At least, from what I could see from the Flamingo Github repository. It could work, but pipe size and corners seem to be limited to standard piping dimensions.

Re: Tube pipe bending
Hi by NormandC,
Thank you so much for your support and during this title.
When you watch this web site video https://www.youtube.com/watch?v=RnIls63PGGY you use to easy understand me.
ı need a table. Each step has 3 parameters (X-Y-Z). The total number of steps will be 20.
For example :
x y z
1.step 200mm +90 degree 45 bending
2.step 300mm -90 degree 120 bending
3.step . . .
. . . .
. . . .
. . . .
.20.step . . .
X parameters: Pipe length.
Y parameters: Rotation of drawn pipes in degrees
Z parameters: Pipe bending angle
when i access x y z parameters then the pipe will be drawn automaticaly.
I need macros for this project.
I'm waiting for your help

Re: Tube pipe bending
That's a nice macro!
Why don't you ask the guy on Youtube for his macro?
I'm sorry, I can't help. I don't know how to program macros. I only ever use the GUI.mesutbarut wrote: ↑Sat Mar 31, 2018 5:09 am I need macros for this project.

Re: Tube pipe bending
I see, thanks for the clarification. So tube bending is closer to the Sheet metal workbench than to Flamingo.

Re: Tube pipe bending
From what I could infer from Flamingo's "pype" tutorials, it uses standard piping elements. It is not modeled as such, but a U-shape ramp will actually be made of three straight pipes and 2 elbows.
