I often find myself in situations where I want to move an object to just one specific coordinate of the 3d-Cursor. Like in below example I want to move a wheel along the y-axis to the center given by the 3D-cursor but I don't want to move it in the other directions (as Shift-S and Selection to Cursor would). I'm aware that I can just copy the x/y/z location of the cursor from the N-Menu. Still, is there a faster way that works with shortcuts maybe?
I don't think this is possible while creating the objects but you can move them all to the same z-coordinate at the end instead. To achieve this, select all the objects you want to move and then set the Y-coordinate (or whichever property to want to have in common). Then right-click the coordinate property and select 'Copy Single to Selected'.
