Extrusion along path to generate a pipe geometry

Posted by Ashish Kumar at May 15. 2018

I want to mesh a given pipe. I have the information about the trajectory of the pipe, which is just lines. I want to generate a hexahedral mesh around the given trajectory (refer link-1). I am trying to accomplish this by creating a face and extruding that along the given trajectory. This works fine until pipe trajectory remains less than 90 degrees. 

Link-1 for trajectory: https://www.dropbox.com/s/w1y9g946hsg46su/pipeTrajectory.PNG?dl=0

If I create the starting face at the vertical section then vertical section geometry is correct, but horizontal section geometry is incorrect, as shown in the following figure

If I create the starting face at the end of the horizontal section then horizontal section geometry is correct, but vertical section geometry is incorrect, as shown in the following figure

Can you please suggest some trick to achieve a uniform solid along all segments of the pipe. Please refer to the following python script for my case.
