Sorry to bump an old thread but i've found a blender equivalent to the pipe building tool for 3dcrafter.
https://blenderartists.org/forum/showth ... ost2783290The tool is no way perfect but i have found it very useful and quick for building complex brakepipes or handrails.
You build an outline of the shape you want with a cube using the edges then just select the edges you want and a pipe will follow the edge.
You can adjust the amount of sides to the cylinder and the size then smooth.
There are some limitations that are easily worked through though. To set the pipe diameter i've found that placing a cylinder the size you want in the centre of one end of your pipe then scale up or down the pipe till it's the same.
You may be a mil or two out but i doubt even the most eagle eyed rivit counter would notice.
You also can't edit or extrude the ends of the pipe but that's something to do with the path it uses(i don't know the proper name).
You can adjust the length though by the paths vertice.
In a nutshell it is worth a try. A pipe that took me litrally an hour to build with Jerrys technique took five minutes with the tool.
I've only been using it a day so no doubt i've not discovered all it can do. The limitations could just be my lack of skill with the tool so far.
