# Booth Layout Guide

## Overview

The Expolinc Booth Designer supports the standard trade fair booth layout types. Each layout determines how walls are arranged, which sides are open, and what components are needed.

## Layout Types

### Inline (Row Booth)

A booth with one back wall and open front side. The most economical and common layout for small spaces.

```
         Front (open)
    ┌─────────────────────┐
    │                     │
    │                     │  ← Side wall (optional)
    │                     │
    └─────────────────────┘
          Back wall
```

| Property | Value |
|---|---|
| **Open sides** | 1 (front) |
| **Typical dimensions** | 3m–6m wide × 2m–3m deep |
| **Walls** | 1 back wall, 0–2 partial side walls |
| **Connectors** | 0–2 corner connectors |
| **Best for** | Small budgets, product display, 1–2 staff |

**Example command:**
```
Build a 4m wide inline booth, 2.5m high, with 2m depth, 
and double-sided side walls
```

### Corner (2-Side Open)

A booth with two adjacent walls forming a 90° corner. Two aisles of foot traffic.

```
         Front (open)
    ┌─────────────────────┐
    │                     │
    │                     │
    │                ┌────┤
    │                │    │
    Side (open)      └────┘
                     Wall B
```

### Face-to-Face

## Grid System

Expolinc components use a **990mm grid** (standard exhibition grid). Wall widths should ideally be multiples of this grid for optimal component fit.

| Grid Units | Width (mm) | Standard Sizes |
|---|---|---|
| 0.5× grid | 495 | — |
| 1× grid | 990 | 950mm (nominal) |
| 2× grid | 1980 | 1950mm |
| 3× grid | 2970 | 2950mm |
| 4× grid | 3960 | 3950mm |
| 5× grid | 4950 | 4950mm |
| Custom | Any | Built from multiple sections |

The layout engine automatically selects the best combination of standard sizes to match requested booth dimensions.

## Component Placement Rules

### Wall Orientation

```
        Z (up)
        │
        │   ┌──────────────┐
        │   │              │
        │   │    Wall      │──→ Y (depth)
        │   │              │
        │   └──────────────┘
        └────────────────────→ X (width)
```

- Walls are created in the XY plane (vertical)
- Rotation is around the Z axis
- 0° = facing +Y direction
- 90° = facing +X direction
- 180° = facing −Y direction
- −90° = facing −X direction

### Corner Joining

When two walls meet at a corner:
- The corner connector is placed at the intersection point
- Each wall is inset by half the profile thickness from the corner
- The connector bridges the gap and provides structural continuity

### Storage Room Placement

Storage rooms are placed behind a wall (on the exterior side):
- Width matches the wall section it attaches to
- Depth extends outward from the booth
- A door is placed on the interior side

## Size Recommendations

| Booth Size | Layout | Components Estimate |
|---|---|---|
| 9 m² (3×3m) | Inline | 1× Classic Frame wall, 2× side walls |
| 12 m² (4×3m) | Corner | 2× walls, 1× corner connector |
| 18 m² (6×3m) | Peninsula | 3× walls, 2× corner connectors |
| 24 m² (6×4m) | Island | 4× walls, 4× corner connectors |
| 36 m² (6×6m) | Island | 4× walls (larger), 4× corner connectors |
| 48 m² (8×6m) | Island | 4× walls + storage rooms |
| 88 m² | Custom | Multiple wall sections, storage, backlit |

## Combining Classic Frame and Light Frame

Classic Frame and Light Frame modules are fully compatible and can be mixed within a single booth:

- **Classic Frame** — Standard wall sections with SEG fabric graphics
- **Light Frame** — Backlit sections for highlights, logos, product emphasis
- **Integration** — Same frame dimensions, connectors, and grid system

Design guideline: Use Light Frame for 20–30% of wall area (brand focal points) and Classic Frame for the remaining area.
