First you have to show the center of mass in your part or assembly (Go in the inspect window and click on the show center of mass case) then you will be able to show the center of mass in the drawing view using the properties and showing it the same way you do for a sketch. Right click on the view, click properties, in the display tab there is a button called part list options and then click list all, there you should see the center of mass in the list.
