Macro to save bodies into individual SOLIDWORKS part documents

{ width=250 }

This macro saves all selected bodies bodies (or all bodies if none selected) from the active part document into individual part documents.

Configuration

Specify the option to handle the transfer of custom properties by modifying the CUT_LIST_PRPS_TRANSFER constant

Specify the output directory in the OUT_DIR. If this variable is empty then bodies will be saved in the same directory as source part document.

Const CUT_LIST_PRPS_TRANSFER As Long = swCutListTransferOptions_e.swCutListTransferOptions_CutListProperties 'move properties to cut-lists
Const OUT_DIR As String = "D:\Parts" 'Export bodies to the Parts directory

Notes

• Bodies remain linked to the original part
• Output files will be named after the bodies
• Special symbols which cannot be used in the file name (e.g. ?, *, : etc) will be replaced with _
• Macro will not create an output folder if it does not exist and will fail

Const CUT_LIST_PRPS_TRANSFER As Long = swCutListTransferOptions_e.swCutListTransferOptions_FileProperties
Const OUT_DIR As String = ""
