When i open an .igs model in Isodraw cadprocess 7.0, all the parts of an assembly are visible. But, when i open the same .igs model in Isodraw 6.1 or 7.3 , there is some dataloss i.e., some parts are not visible or missing. Can ayone explain me what might be the problem or do i need yo reinstall the softwares or are there are any plug-ins missing.
Thanks in advance.
