This tool selects and highlights only a single object of each group of elements with the same assembly or single part mark (depending on the Single Parts / Assemblies switch).
If the Drawing - Single Part tool is called, a shop drawing for each position number group is created. Without this command, each part is detailed as many times as the parts exist in the model if the system default is set to allow duplicate drawings.
Access the command
In the Output tab Part marks panel, click (Select objects with different part numbers).
Command line: _AstM5CommEqualPartsOnePartOutOf
Select objects with different part numbers
Individual parts for each part number should be selected for drawing creation if done manually rather than by a process.
