This opens a screen that has three tabs.

General tab:

This tab allows a user to select whether the Model Inspector will be shown each time calculations are completed. The Model Inspector may also be started by clicking Tools > Model Inspector on the main menu.

Library Updates tab:

This tab allows the user to select their preferences for managing TREATs two distinct library types: Non-Editable and Editable. Non-Editable Libraries should be updated by default to take advantage of the new appliances, surfaces, etc. that are added to the libraries periodically.

Inputs in the Editable Libraries area allow selecting editable libraries that will be updated with editable data set on your machine when a TPGX file is opened. These may include contractor data, customer information, specific workscopes, etc. This functionality should be used with caution, because it allows overwriting the libraries stored in the existing TPGX file with new ones, which may cause data consistency problems, if the file is again open by previous users of the TPGX.

Note: Once a user adds information in one of the editable libraries, you must select Project Group -> Store Editable Libraries -> [Select which libraries to update] and then click Store. These options will now be available in the corresponding dropdown menus whenever a new project is started. These options will also become available for selection in older Project Groups as well.

After you import daily weather data into a TPGX, you may want to update the libraries for other TPGX files with the latest weather data. This may be done as follows:

  • Select Project Group -> Store Editable Libraries menu option and click OK to Daily Weather Library upgrade. The Daily Weather Library will be stored to the central library depository.
  • Open Project Groups -> Options window. In the Editable Libraries area select Prompt to Upgrade Libraries and select Daily Weather Data checkbox.
  • Click Save to save the new inputs and close the window.

After that, each time you open a TPGX, the selected editable libraries will be replaced with the versions of these libraries stored on your computer.


Use caution when upgrading editable libraries — especially the Contractor, Customer and User libraries — to prevent data loss or inconsistency in project data. For example, you may have a project in ProjectGroup1.tpgx that has customer John Smith, who is customer #3 in the Customer library. While working on ProjectGroup2.tpgx, you choose to store its Customer library to the internal library depository. In that version of the library, customer #3 is Tom Brown. If you replace the Customer library in ProjectGroup1 with the Customer library from ProjectGroup2 using the TREAT library upgrade feature, then all projects in ProjectGroup1 that referenced John Smith will now have Tom Brown as a customer. Information for John Smith will be lost.
