OpenSCAD - Profile along a Path

OpenSCAD is a quite powerful tool, but sometimes you happen to hit its limits.
One of the "features" i was missing is the ability to create a profile along a given path.
So I developped a python library, which extends openSCAD with this feature, but also other generative features can possibly be added.

Prerequisites
-----------------

* Python 3.5 installed
* alongpath.py
* samples (optional)

Use the samples and/or create own applications with fit your needs
This is how it works:

SETUP
---------

* Edit the python sample file with your needs, use python syntax to create a profile and a path function
* use alongPath to combine these functions
* add an openSCAD Section which uses these figures
* use writeOpenScad to write the openSCAD file
* run the python script
* open it with openSCAD to display the result

USE
-----

To change/alter/tweak the result:

* change parameters in the python file
* save it
* run it.
* OpenScad will automatically updat
