Can anyone please tell me about a software that can convert large iges models to stl models.

I have a rather large (175 Mb) iges model that I want to convert to an stl file. I want upload the stl file to my Wordpress website, because the software will not accept iges or jt models. Also, the maximum file upload-size for Wordpress is 20Mb.

I tried one of the free-on-line file conversion services, but it could not handle the large iges file. The resulting stl model was garbage. Then I tried converting a much Smaller iges model of 3.5Mb, and it converted successfully into a very usable 413kb stl file, a reduction in file-size of about 11%.

If anyone knows about a converter that will handle large iges files, free or otherwise, please let me know.

Thanks!
