|Build Status| |Documentation Status|

A python package for the analysis of arbitrary cross-sections using the finite element method written by Robbie van Leeuwen. sectionproperties can be used to determine section properties to be used in structural design and visualise cross-sectional stresses resulting from combinations of applied forces and bending moments.
