IGES Import
Message 1 in thread
Hello,
I know this might be a little bit besides the group topics but maybe
the group can point me in the right direction :)
I currently write an application that is used as a CAM system for a
robot. At the moment I can only load in geometry that exists as stl
(triangle net) file. In the near future I need to implement support
for nurbs surfaces as well and therefore would like to import and
export also iges files....
Unfortunately I have yet no idea how to start and I also thought that
there might be some free available source already for this problem.
Maybe the group has more information on such a topic.
Thank you very much in advance.

A little beside? I think one could use this mail to define what's definitively
out of the scope of this list;)

IGES is an ANSI standard, so just read the text...

There are several translators (just because IGES is often used as intermediate
data representation for data exchange), every commercial CAD system I'm aware
of is able to import IGES. PythonCAD is free but doesn't contain an IGES
import (but its maybe a point of contact for you). I know that there are
IGES->PostScript converters, which has been used to create images from IGES
files (for documentation purposes). Maybe some of it are free and its source
code is available.
Not much help, but maybe a starting point...

Hi to all of you.
in fact i know that this is very off topic...but I want to implement
the iges import into a qt based application and therefore maybe its
not that much off-topic anymore :)

Shure I can just read the text but why should I make myself the work
if there is already existing code I could probably use :)

Thanks for those hints...I will look this up.

Thanks anyway very much.
I will keep you informed about the status.
Best regards,
