iges | A portable | Compression library

I can not figure out how to prevent code dublication for that code block.

There is a base class That is Base_Reader and derived types like JT_Reader, IGES_Reader etc.

But base class dont have methods that childs have. Also I can not Change these because they come with dll.

Here are code sample;

i wanna insert an ansys apdl code code text in my thesis. I have tried the \begin{lstlisting} for my code (english) since i have tha package. My thesis template is put to have greek as default language so when i compile the lstlisting in latex i get this output latex output (greek characters). I have tried use \eng{} inside or outside of the \begin{lstlisting} but i get greek characters either way. this the code :

I'm having challenges with some IGES/STEP models where my code is not able to classify faces bases on the underlying classification of edges i.e whether an edge is a Straight line(non-rational Bspline curve) or arc(rational Bspline curve). I have been using the code below (which works for some models):

I'm looking to convert a series of ordered (pretty dense) 2D points describing arbitrary curves into a NURBS representation, which can be written into an IGES file.

I'm using scipy.interpolate's splprep to get a B-spline representation of the given series of points, and then I had presumed the NURBS definition would essentially be this plus saying all weights are equal to 1. However I think I am fundamentally misinterpreting the output of splprep, specifically the relation between 'B-spline coefficients' and the control points needed to manually recreate the spline in some CAD package (I am using Siemens NX11).

I've tried a simple example of approximating the function y = x^3 from a sparse set of points:

So I have this function to import 3d file formats in my application but can't filter the file dialog to only show 3d files. I am using this way of filtering:
