Dawn I do your process. I export placement file, delete U29, change D2PAK with TO-263-3 in placement file, import placement file nothing happen but when I change D2PAK again, import file again it place D2PAK with REFDES U29. I Think I do some wrong kindly correct me.

Do you have the TO-263-3 footprint defined? A quick test, do a Place Manual (Advanced tab make sure "librry" is selected). Placement List pull down to Package Symbols. Do you see the TO-263-3?

Hello,
Just export your library in the path where is you brd file by using the File-->Export--Libraries, check all the options, let the dot in the directory line and click OK. You obtain all your packages and pads file...
Export the netlist by using the File-->Export-->Netlist/w properties, edit the netlist.txt file then replace your package component in it. The file structure is easy to understand. Use the file import-->Logic, folder other and check supersede all logical datas, the clic on import...
You will see the changes immediately.
