Lets look at an example
 * Create a new file and add from the Part workbench a cube and a cylinder. We will stack the cylinder onto the tube. First we fix the base part, in out case the cube. Select the bottom face of the cube and select the "Locked" constraints (first icon in the Constraints toolbar). Select the top face of the cylinder and the top face of the cube. Then select the "Plane Coincident" constraint. Now the cylinder is moved into the cube and in the tree a new leaf with two childe nodes was added under 'Constraints'. Additionally the same two child nodes were added under 'Elements'. If you cylinder is inside the cube instread of on top of the cube, lets correct that first: select the child node under 'Constraints' that shows the cylinder face and with a right click in the context menu select 'Flip Part'. Now the cylinder is stacked onto the box.
