Functional Purpose

What This Dialog Does

Panel Dimensions & Pick Point Configuration

The pp_dlg dialog configures fundamental panel properties:

  1. Panel dimensions (width, height, thickness)

  2. Pick point placement (lifting insert locations)

  3. Auto-placement options (automatic grid patterns)

  4. Engineering verification requirements

  5. Face orientation (left/right)

User Need

Essential Panel Definition

Before adding features (welds, chamfers, etc.), users must:

  • Define panel physical dimensions

  • Specify lifting point locations for handling

  • Ensure pick points are engineered for panel weight

  • Set up grid for automatic placement options

Typical Workflow

Basic Panel Creation:

1. User in mp_dlg clicks [Panel Parameters]
2. pp_dlg opens
3. User enters dimensions:
   • Width: 12'-0"
   • Height: 8'-0"
   • Thickness: 6"
4. User enables auto pick points (ppa checkbox)
5. User selects grid: 2 columns × 1 row
6. System calculates positions
7. User clicks OK
8. Returns to mp_dlg with parameters set

User Interaction Examples

Example 1: Auto Pick Points for Standard Panel

Scenario: 12’×8’ panel, 2 pick points

1. User: In mp_dlg, clicks [Panel Parameters]
2. pp_dlg: Opens
3. User: Checks [x] Auto place Pick Points
4. User: Selects Columns: 2, Rows: 1
5. System: Calculates positions:
   • ppd1 = 4'-0" (1/3 from left edge)
   • ppd2 = 8'-0" (2/3 from left edge)
   • ppe1 = ppe2 = 4'-0" (mid-height)
6. User: Verifies positions look reasonable
7. User: Clicks OK
8. Result: 2 pick points positioned for balanced lift
9. Note: "Must be verified by Engineer" warning

Example 2: Manual Pick Point Placement

Scenario: Irregular panel requires custom placement

1. User: Opens pp_dlg
2. User: Unchecks auto-placement
3. User: Manually enters:
   • ppd1 = 3'-0" (first pick point)
   • ppe1 = 5'-0"
   • ppq1 = L (left face)
   • ppd2 = 9'-0" (second pick point)
   • ppe2 = 5'-0"
   • ppq2 = L (left face)
4. User: Leaves other fields blank (unused)
5. User: Clicks OK
6. Result: 2 pick points at specified positions

Example 3: High Panel with 4 Pick Points

Scenario: 12’×20’ tall panel needs 2×2 grid

1. User: Opens pp_dlg
2. User: Enables auto-placement
3. User: Selects Columns: 2, Rows: 2
4. System: Calculates 4 positions:
   • Row 1: ppd1=4'-0", ppd2=8'-0" at ppe=7'-0"
   • Row 2: ppd3=4'-0", ppd4=8'-0" at ppe=14'-0"
5. User: Reviews engineering feasibility
6. User: Clicks OK
7. Result: 4-point lift configuration

Engineering Considerations

Warning: Engineer Verification Required

Critical Notice:

"Must be verified by Engineer"

Why Required:

  • Pick point locations affect structural safety

  • Inadequate placement can cause panel failure during lifting

  • Load distribution must account for:

    • Panel weight

    • Dynamic lifting forces

    • Embed capacity

    • Concrete strength at lifting

Best Practices

Column/Row Selection:

  • 1 column: Not recommended (unstable)

  • 2 columns: Standard for most panels

  • 4+ columns: Heavy or large panels only

Spacing Guidelines:

  • Minimum edge distance: 12” (typical)

  • Maximum span: 16’-0” (varies by panel type)

  • Balance required: Center of gravity alignment

Load Calculations

Formula (simplified):

Pick Point Load = (Panel Weight × Safety Factor) / Number of Points

Safety Factor: 2.0 minimum (dynamic lifting)

Special Features

Auto-Calculation Algorithm

Spacing Calculation:

; Horizontal spacing
(setq h-spacing (/ panel-width (+ columns 1)))
(setq positions (list h-spacing (* 2 h-spacing) ...))

; Vertical spacing
(setq v-spacing (/ panel-height (+ rows 1)))

Example (2 columns × 1 row on 12’ panel):

Spacing = 12' / (2+1) = 4'-0"
Positions = 4'-0", 8'-0"

Face Direction (L/R)

Purpose: Specifies which panel face has pick point

Options:

  • L (Left): Pick point on left face (when viewing from front)

  • R (Right): Pick point on right face

Typical: All pick points on same face for consistency

Grid Limitations

Maximum Grid: 8 columns × 4 rows = 32 pick points

Typical Usage:

  • Small panels (< 10’): 2 points (1×2 grid)

  • Medium panels (10’-16’): 4 points (2×2 grid)

  • Large panels (> 16’): 6-8 points (custom)

Importance

Why CRITICAL:

  • First configuration step in panel creation

  • Pick points are structural safety feature

  • Required for every panel

  • Affects panel handling and erection

Dependencies:

  • Many dialogs reference panel dimensions

  • Pick points affect crane planning

  • Critical for construction sequencing


Technical Notes

Pick Point Numbering

Grid Numbering (row-major order):

Column:  1    2    3    4   ...
Row 1:   1    2    3    4   ... (ppd1-ppd8)
Row 2:   9   10   11   12   ... (ppd9-ppd16)
Row 3:  17   18   19   20   ... (ppd17-ppd24)
Row 4:  25   26   27   28   ... (ppd25-ppd32)

Coordinate System

Dimensions measured from:

  • Horizontal (ppd): Left edge of panel

  • Vertical (ppe): Finished floor elevation

  • Face (ppq): Left or Right face
