Copying one part to project library copies whole library

#Tcl Script to help to copy a part from the source library to destination library.

# Please copy the tcl code to a notepad or notepad++ and save it as copy_part.tcl.
#Now open Orcad Capture and go to capture command window(if command window not visible go to View-->Command Window).
#Type in Command Window , source {<path_of_tcl_file>/copy.tcl}and press enter.

#After sourcing the tcl code, open the destination olb, part is now available to the olb.

#Getting the current session.
set lSession $::DboSession_s_pDboSession
DboSession -this $lSession

set lStatus [DboState]

#Package/Symbol/part name that is presnet in source library and need to copy to destination library
set partName "LMC6482"
# puts $partName

set partNameCS [DboTclHelper_sMakeCString $partName]

#set the source library from which you want to copy the part
set srcOlb [file normalize {C:\Cadence\SPB_17.4\tools\capture\library\OPAmp.olb}]
#set the destination library where you want to paste the library
set destOlb [file normalize {C:\Cadence\LIBRARY2.OLB}]

set srcOlbCS [DboTclHelper_sMakeCString $srcOlb]
set destOlbCS [DboTclHelper_sMakeCString $destOlb]

#Get the dboLib from the source library
set srcLib [$lSession GetLib $srcOlbCS $lStatus]

# puts $srcLib

#Get the Dbolib from the destination library
set destLib [$lSession GetLib $destOlbCS $lStatus]

#Get the package from the source library
set pkageName [$srcLib GetPackage $partNameCS $lStatus]

# puts $pkageName

#Copy the package to the destination library
set copyPkg [$destLib CopyPackageAll $pkageName $partNameCS $lStatus]

#Mark library for save
$lSession MarkAllLibForSave $destLib

#Save the library
$lSession SaveLib $destLib

#Remove the libarary form the current session
$lSession RemoveLib $destLib

Hope this helps!

 The root cause of this problem is:LMC6482 have Part Aliases

you can save OPAmp library as a temp library ,then  delete all  Aliases . and then copy LMC6482 from the OPAmp library and then paste it into the project library
