i need a script to make edges become pipe,just like skin operation,but i need circle shape not square£¬please help me£¡
Not sure this will help but it’s worth a shot:
(Assuming you have a poly model of the thing you want to make into pipes)
- Edit mode > select all > delete > only faces
- Object mode > Object > Convert to > Curve from Mesh/Text
- Use the Curve settings in the Object Data panel to extrude out the pipe shapes (in the “Geometry” section).
Example (I started with a torus):

Add a subsurf modifier!
but the ‘curve bevel’ method is not so good!
so that’s the reason i don’t wanna use ‘convert mesh to curve’
i think turning on/off 3d for curve might help.also try ctrl+n before converting to curve.
It seems like there was a “make pipes from mesh” script a while back. When I get home this evening I’ll check my files.
thanks for your help,safetyman!
Turns out the “make pipe” plugin I was thinking of was for Lightwave, not Blender. 
Hopefully the suggestions we’ve made so far will help.
check catalogue script
there is one for doing this type of edges effect
dont’ remember what the name is !
happy bl
I wanna creat a petro chemical plant,so i need creat a lot of pipes,i don’t wanna use CAD software,so who can help me to write a script to create these pipes easily!!
this is the pic i wanna to create,but the pipes ,you know it’s so hard to
it’s hard to accomplish in blender!
Not so hard…Duplicate cubes, grab, scale, set Edge-mode , select > random edges, separate selection, convert to curves, set bevel depth and bevel resolution.

@TynkaTopi: There is this distortion thing OP mentioned in #4 -
Beveling cubes before select loop to convert might help, likely.
as mention before you can make a mesn path and use the skin modifier
or for rounded but this will require some editing at different location
or use bevel curves
if not for close shot
anothere way would be to use the wireframe clasdd ine dit mode
but this makes more like square tubes not rounded one!
happy bl
I approach the problem this way: Script or not, you will need to layout piping run geometry. Make this out of edges. Layout piping elbow, and put object center at the corner of where pipe centerlines intersect. Duplicate the elbow as much as you need. Snap the elbows on to the pipe run corners and rotate to proper orientation. All you do now is to joint all the elbows to gather and bridge the ends to form pipe run.
Since all the pipes and elbows are standard size, to create additional pipes, just duplicate and edit pipe run; make it longer, shorter, put bend in different location.
I didn’t have much time to make it better…I wrote you step below
1.Delete the cube
2.Add Cylinder
3.Into edit mode delete top and bottom faces
4.Select top vertices(whole circle) and press alt + r
5.Now in the properties panel on the left make x to be 5
6.Select the far right circle of the pipe and move it along z axis until You think it’s good and also the one next to it if needed
7.Smooth it
8.Add subdivision surface modifier
9.Add more modifiers if you want(I only smoothed it and added subdivision)
ridix’s way is better 
@superlimo: That picture can’t be done in 1 or 2 clicks – it will take time, no matter what method you use.
@JA12: I never know about the wire frame thing! Thanks for the tip.
@ridix: Great way to make some pipe runs.
