- Visual comparison with reference

Helper Methods

Nesting Operations

DoNewQuickNest(bool singlePart = false)     // Create quick nest layout
SelectPartsBy(string option)                 // Select parts by criteria
Renest(RenestOption option)                  // Perform renesting operations
Recompute(RecomputeOption option = ...)      // Trigger recompute/retooling

Validation Methods

CheckLuxScreen(string folder, filename = "test")        // Bitmap comparison
CheckPartsInLayout(string folder, filename)             // Layout data comparison
CheckSelectedParts(string folder, filename)             // Selected parts validation
DoAnyPartOverlaps()                                      // Boolean: Parts colliding?
AreAllPartsNestedWithinSheet(bool includeTooling = ...) // Boolean: Parts in margin?

Key Enums

RenestOption

RearrangeToCreateRemSheet = 0  // 'a'
RearrangeToFullSheet = 1       // 'b'
SpreadPartsAlongX = 2          // 'c'
SpreadPartsAlongY = 3          // 'd'
SpreadPartsAlongXY = 4         // 'e'
Cancel = 5                     // 'f'

RecomputeOption

RetoolAllElements = 0              // Drop existing & retool all
ToolOnlyUntooledElements = 1       // Tool only untooled parts
Sequence = 2                       // Recompute sequence
Routing = 3                        // Recompute routing
Cancel = 4                         // Cancel operation

Key Patterns Used

UI Automation

Keyboard input: Utils.Type() for commands (e.g., ‘l’ for CutCAM, ‘n’ for nesting)
Mouse operations: Click, drag-and-drop, double-click, mouse wheel
Keyboard modifiers: Ctrl, Shift for special interactions

Part Coordinates

Parts are identified using pixel coordinates:

new (50, 90)        // Base part position
new (150, 90)       // Target position
new (87, 167)       // Intermediate point
new (1500, 1500)    // Far position for arrays

Flux Scripting Integration

Validates layout and part state using Flux C# scripts:

Utils.RunScriptWithOutput(commands)  // Execute Flux script & get result
Flux.Layout.Current                  // Access current layout
Flux.Layout.Current.Children         // Access parts in layout

Visual & Data Validation

Screen comparison: Renders to PNG, compares with reference (95% tolerance)
Text comparison: Validates layout dumps, part outlines, NC data
Bitmap comparison: Visual verification of rendering

Architecture Highlights

Modular design: Separate helper methods for common operations
Fluent assertions: Direct state validation via Flux scripting
Reference-based validation: Compares against baseline files/images
Multi-modal interaction: Keyboard, mouse, and scripting commands
Tolerance-based comparison: 95% bitmap similarity threshold for visual tests

This is a sophisticated layout/nesting validation framework ensuring correct part arrangement, positioning, and display in the Flux application’s cutting optimization engine.
