I am renaming the part which is in large assembly by right click the part in model tree, component properties, change the component name so that file name in the solid works explorer will be unaltered. it is working fine and immediately it reflects in model tree. But, it is fine in my system only and once check in and open in another system, the component name in the assembly is same as per file name. i uncheck the mark in options=> external reference=>update document name when documents are replaced. i can rename the file name itself in explorer. But, i have used same file for more than ten instances with different equipment number. So, i need this option. Kindly give an idea to export the local memory to server so that the rename can be available in all other system.
