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).
Note: Objects that were previously highlighted in red will be kept. To remove the highlight, first clear marked objects. See Unmark objects.
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.
Note: This command is not required if creating drawings using a drawing process as the process automatically filters out a single instance of each part mark.
To access the command
