Hey I am trying to do a directory search using c# for soildwork parts that are duplicates or are the same part but with custom properties. I already compared parts of the same size with each other but that is not very accurate. Is there anyway for me to access solidworks hash data or part dimensions or unique part numbers that solidworks assigns to a created part. I am fairly new to solidworks and i have been told of the compare part option in solidoworks but i want to compare all parts with one another and find the duplicates. Please help.
