ISSUE FACED in SOLIDWORKS: Very limited functionality available in the Pack & Go or Copy Tree. Parts from the design library are always copied. Limited file naming possibilities. Properties need to be updated manually. SOLUTION in CustomTools: Use your own file naming rules. Modify and propagate custom property values. Exclude files from the design library. Update drawings with new property values. BENEFITS: Easily reuse existing design data. Save time. Keep the folder structure under the main assembly. Rename your files based on your own naming convention.
