I can do this conversion for you, but i think I need to see the file, all depend on the usage you need to do with the final product.
if you need to use the IGES for a CNC machine the file meed to be checked also on surfaces in order to have your tool pat smoot.
so please if you send me the file I can be more precise on the job that need to be done, any way my bid is there and the price is set.
hope to have news from you .
have a nice day
