igesout updated

IGES Converter for points, lines, and NURBS curves and surfaces

IGESOUT converts nurbs surfaces, curves and polylines to a single compact IGES format file.

Vectorizing was implemented wherever possible, so the code should run quickly.

Daniel Claxton originally crated igesout but seems to be currently unavailable to maintain it. Assuming his consent, I am taking the liberty to upload this version which fixes a number of issues that prevented my files from being loaded correctly.

Important: If you are upgrading from a previous version and you are exporting geometry measured in inches, you need to update the code to reflect that, as I have changed the default to millimeters.

To use inches, please call the export function like this:

igesout(geometry,filename,'unitflag',1,'units','INCH')

I have only tested this on Windows 11. It should work on macOS and Linux as well, but I have not tested this. Windows versions before 7 will probably not work, but this can be fixed by setting the default author to an empty char array.
