Electrical – Project libraries don’t show in Altium 14.1

You probably have edited the the schematic symbol in Sch library after placing its footprint on the layout design.

In situations like this, you need to update your schematic design from library (Tools/Update From Libraries...), then update your PCB with the updated schematic. If problem still there, remove the footprint from PCB file and update the PCB file with schematic again.

Also make sure the symbol in schematic sheet has the same footprint model name as it has in Schematic and PCB libraries.

• Create a folder and name it "Altium Libraries" (or any other name you prefer). This folder will contain all your libraries.

• Within that folder create several subfolders with names like:
  "Resistors" (for all resistors you will add to the resistors library),
  "Capacitors" (for all capacitors you will add to the capacitors library),
  "Atmel" (for all parts from Atmel you will add to the this library),
  "Samtec" (for all parts from Samtec you will add to the this library),
  ...
  

• with Altium open and running, click on file tab (left bottom corner of work space, find "Blank Project (library Package)" and click on it. A new Library Project will be created.
• in Projects tab (next to the Files tab you clicked before) right click on the new library project and add to the project a new PCB library and a new Schematic library.
• save this project and its two added files in the "Resistors sub-folder" with proper names (such as Resistor.LibPkg, Resistors.SchLib, Resistors.PcbLib"
• now add all Resistors Schematic symbols (each with its P/N as Design Item ID), Then Footprint with name such as "0402-0.4mm", "1206-1.2mm", ... and add to each symbol the correct footprint.
• right click on "Resistors.LibPkg" within the Projects Area (left column of your screen) and compile it as integrated library. Don't forget to address compile errors and warnings.
• Do these steps for all other libraries. You are going to have several compiled libraries
• Now in your real design project, try to find "Libraries tab" and click on "Libraries..." button and install the integrated libraries (if you can't find this tab go to the View menu/Desktop Layout/Default.)
• This way you always have your libraries for all projects. Whenever you have a new component, simply open the relevant library project, add the component and its footprint, and recompile.
