Can't extrude symmetrically in timeline - File attached

[rhetteshleman]

I may be asking for too much, but I'm trying to extrude the holes through the laptop base brackets (two small ones) after I've already extruded them for the arm itself. Hopefully the file will explain better. Also, I'm trying to use the 'Manufacturing Model' feature in CAM but I can't get it to even show up. It's enabled correctly in my preferences but I'm hoping to try it out for nesting all these parts. 

I know this file is a disaster, it started out nice and clean. Thank you for the help.

I hope I am looking at the correct holes.  Take a look at the Screencast where I make a suggestion on moving a couple of your bodies into the component containing the matching body.  I then demonstrate adding the holes from the existing sketch profile.  To get the select list where I pick the profile, hold down your left button while hovering over the profile.  That may not be obvious in the video.

As far as the Arrange command, you will not have access to it is your Fusion 360 license type is Personal.  If you have another type license, make sure it is enabled in the Preferences.

Thank you for that incredible response, John. You answered all of my questions and more. I have a subscription but was looking in the wrong place for the arrange and manufacturing model. Have a great holiday
