There are times after the first load into SAMM while you shakedown / debugging when it is useful to modify some model code without having to go through the full model reload procedure. 

  * In Documenter make the code changes in the .dmm diagram and run dimensional analysis which will refresh the code on the server.
OR
  * Alternatively, in the appropriate ''sim'' or ''cal'' directory, locate the .t file for the calculator you want to modify (e.g. cal/dwellingsC.t).
  * Make the desired code modifications in this file. 

Then
  - Open SAMM 
  - //Set File Path...// to the appropriate cal or sim directory.
  - Go in the diagram to the calculator you want to patch the code for and open it up
  - Go to the Windows menu and choose Hierarchy 
  - Select from the menus //Hierarchy Actions | Reload Calculator...//.
  - The code can be verified from //Hierarchy Actions | Show Code...//.
Note: every variable downstream of this procedure will be out of date and need to be re-evaluated.\\ 
There are two ways to approach re-evaluating the model.
  - Single calculator
    - With the Diagram window active select Unevaluate Variables from the Diagram Actions menu.
    - Double click on the variable of interest in the diagram and the model will re-evaluate all of the unevaluated variables
  - Scenario
    - With the Scenario window active select Unevaluate from the Scenario Actions menu.
    - Double click on the variable of interest in the diagram and the model will re-evaluate all of the unevaluated variables

Note: the diagram code will not reflect the updated code. However, this can be manually updated from //Windows | Frameworks // and then //FW Actions | Load Diagram//.
