Hi, as an IT professional I have a problem with files SLDASM, namely: Sometimes it is so that the engineer writes a file on a network drive (under control of Novell), and when you try to re-open the file using SolidWorks 2010 SP 4.1 SolidWorks indicates that the file format is unsupported. The only possibility is to create the assembly file from the beginning. Moreover, E-Drawning opens the file without any problem. Does anyone of you can just have that symptom? problem does not occur in the case save on the local disk. I would be grateful for every response, I do not know what else I can do that is so not happening.
