 ## Introduction
 
-This project is about autonomous SBC case creation. It utilizes the SBC Model Framework project to automatically generate cases based on the data for any of the 61 current SBC contained within the framework. This allows legacy, current and future SBC to have multiple cases available on day one of their inclusion in the framework. There are multiple base case designs(shell, panel, stacked, tray, tray-sides, round, hex, snap, fitted) available and each allows for different styles within the design.
+This project is about autonomous SBC case creation. It utilizes the SBC Model Framework project to automatically generate cases based on the data for any of the 84 current devices contained within the framework. This allows legacy, current and future SBC to have multiple cases available on day one of their inclusion in the framework. There are multiple base case designs(shell, panel, stacked, tray, tray-sides, round, hex, snap, fitted) available and each allows for different styles within the design.
 
 All case openings are created automatically based on SBC data and the dimensions of any case design can be expanded in any axis allowing for the creation of larger cases. If you reposition the SBC in a case, you will see i/o openings created or removed appropriately based on it’s proximity to the case geometry. These cases might be useful for prototypes or other in house uses to quickly and easily create standard, specialized and custom SBC cases thru different case designs, styles and accessories.

 All case data is stored in the json file sbc_case_builder.json with the accessory data stored in a separate file structure in sbc_case_builder_accessories.cfg.  An accessory group name for a given case is stored as part of the case data in the json file.  This allows for the reuse or sharing of an accessory set by different cases and can be used to manage groups of accessories.

 ### Accuracy
 In the past there was been no way of validating whether a SBC Model Framework model and it’s components were dimensionaly accurate in their size and placement other then trial and error. Along with producing cases this project provides a much needed model validation tool to assure model accuracy thru the use of test cases. It works on the very simple premise that if the real SBC fits the test case then the virtual model is accurate or otherwise shows were corrections are needed. This will further increased the overall accuracy of models.
 
-There are currently 58 SBC represented by 54 models, from 10 manufactures in SBC Model Framework.  Some SBC in SBC Model Framework have not been validated or may be missing component data and may produce one or more aspects of a case incorrectly.  SBC status is noted in sbc.png, the README.md file and at the beginning of the SBC entry defined in sbc_models.cfg, all a part of SBC Model Framework.  The color coded indicator of an SBC’s verification and completion as indicated in sbc.png is as follows:

 “tol”, located at the bottom of the Adjustments Tab, is a  tolerance fitment adjustment for the snap, fitted, round and hex tops.  Adjust accordingly if the tops are too tight or loose.
 
-Template creation and i/o panel layouts in a dxf format can be easily created and integrated into other designs or for hand fabrication by sectioning a case panel for the desired SBC. The case design “panel” will most likely work best.

 ### Case Designs and Styles
 The case naming convention for standard cases in the configuration file follow the basic form of “sbc”_”design”_”style” e.g. c4_shell or c4_tray_vu5.
