Hi,
what i want do is, read mxs, check for certain objects by name, append matching to new mxs and save.. simple, but always python crashes after i call getObjectNames(). If i am getting object by name, everything is fine, but in this case, i am not going to know the name before real processing..
any ideas? am i doing something wrong? thanks a lot.
environment is: Mac OS X 10.7.5, Python 3.2, pymaxwell 2.7.20..
