![Image](SBC_Case_Builder_GUI.gif)
### View Tab
The View Tab allows the selection of various viewing modes and the selection of the device model for which a case is being generated. The *view* pickbox allows the respective case to be displayed as a 3D model, platter for 3D printing and as an individual case part, which can be selected using the *individual part* pickbox. The *section part* checkbox sections the selected part for dxf or other 2D export. The *sbc model* pickbox selects the device (SBC, MCU, Motherbaard, etc). The *sbc off* and *sbc information* are self explanatory. The *sbc highlight* shows the subtractive openings that are being automatically created by SBC Model Framework while the *accessory highlight* shows the subtractive openings being generated by entries in the file sbc_case_builder_accessories.cfg. The later is useful when trying to visually place a subtractive accessory.

### Folded Case Adjustments Tab
This tab exclusively deals with folded cases. At this time the bend allowance equations are not complete and limits its use to paper and other thin materials with a low bend radius. Once folded metal cases are implemented the bend allowance equations will be complete and allow for any bendable material of any given bend radius. With that said, these adjustments are used for the paper_full-top and paper_splt-top case designs and the *material thickness* and *bend Allowance* adjustments still need to be set appropriately for proper use. The *bottom clearance* adjustment allows additional bottom height adjustment for those wishing to use user provided standoffs on the bottom of the device for better stability. The *flat blank section* checkbox generates a flat blank based on the aforementioned settings. Once it has been generated the model must be rendered(F6) to produce a 2D blank that can then be exported as a DXF or SVG file for printing or fed to a CNC cutter.

### Rack Mount Case Adjustments Tab
Both 1U and 2U, 10" and 19", rack cases are configured in this tab. The first entry *rack width* selects if 10" or 19" rack cases are being created. The *rack size* sets wether 1U or 2U. There is a 2mm wall in front of every removable bay. *removable bay height* allows the tray height to be reduced to form an opening which allows for tray removal and venting when installed with other rack cases above. The remaining tab is divided into six groups of settings each representing a virtual bay. Each bay group specifies the SBC thru the pickbox *Rack Bay1* respectively. With *rack bay1 xyz loc* and *rack bay1 rotation determining the position and z-axis rotation. The type of bay is set in the *rack bay1 face* pickbox followed by two checkboxes for the internal dividing wall, rear fan and a bay conduit selection pickbox.

### Using Accessories Dynamically
Having SBC Case Builder running while editing the sbc_case_builder_accessories.cfg file using a seperate text editor will aide in visual accessory manipulation and placement. OpenSCAD will automatically regenerate the model preview when the accessory configuration files is saved.

## Accessory Subsystem
Case accessories entries are kept in the file sbc_case_builder_accessories.cfg. Newly created accessory group names also need to be added to the variable accessory_name in sbc_models.scad on or around line #128 in order for them to appear in the GUI pickbox. Any new accessory group names must be added to the pickbox entry or they will not be present in the GUI. This can be done manually or the helper script get_customizer_values.scad can be used to generate a complete accessory names list for copy and paste from the console.
