Python IGES Geometry Library¶

This is the documentation for the Python IGES Geometry Library project, it is meant to be an all-encompassing document about every facet of the program - however a number of trivial or irrelevant details may be missing. The features and accompanying manual is in constant development too - so prudence is advised when there is something undocumented.

Working with this library should be simple, you will have your geometry in the form of points - whatever those points represents is up to you. Generally, those points define a profile or the outside of a surface they are stored in a numpy type or standard python type in the form [[x], [y], [z]] where z is optional. The next steps is to push your data into the IGES geometry, how and what way is covered in the tutorials section; also there are example files that show how to generate geometry that can be found in the Wiznet iges file examples page.

Beyond what is a canned, watch out there be dragons message, this package is useful when it comes to using Python to do something interesting - and in this case, that interesting thing is to make 3D objects. This library, package, or whatever the reader wants to consider it comes out of another project that is about the design of turbomachinery; what does this mean? Well simply that the library will be always kept up to date to work with Ansys and OpenFoam.

Realistically, this library is a trivial piece of code so there is only so many virtues that can be extolled about its development.

It should be mentioned that as a library this work comes under an AFL licence. This means for commercial players or others who are confused by licencing that you are free to link to and use the library with a program of any licence - however, modifications to the pyiges library (aka, a derivative work) must be made public (and preferably though a merge to the original work on GitHub) (clause 1, c). Why AFL? Then developers can all take advantage of the improvements that have been made. This public distribution of derivative works is similar to a number of other licences, however AFL is also easy to read. Check it out on http://opensource.org/licenses/AFL-3.0

The following sections are specifically about the development and source code of the project. Make reference to Index and Module Index which provides a general and module index respectively.
