Comprehensive Documentation of the Production of a Tourist Attraction Planning Sand Table
Scale Control: 1:2500 full-scale terrain reproduction
Core Objective: To achieve three-dimensional visualisation of the airport cluster, high-speed network, and urban nodes in the mountain-plain transition zone
I. Terrain System Casting
Mountain Range Skeleton Shaping
High-density EPS panels CNC-cut into 15 layers of contour line bases
Fault cliffs manually shaped with epoxy modelling paste to recreate weathered rock layer textures
Valley depressions filled with semi-transparent blue resin to embed riverbed structures
Surface Ecological Layer Construction
Forest areas: Alternate spraying of 0.2mm/0.5mm mixed grass powder using an electrostatic flocking machine
Exposed rock layers: Basalt powder mixed with acrylic gel scraped and sintered
Plain areas: Mineral gypsum base layer, imprinted with real farmland texture patterns
2. Precision replication of transportation networks
Layered road network construction
Airport Expressway:
3mm amber-coloured acrylic laser-cut grooves
φ0.3mm optical fibres embedded in the grooves, covered with a frosted film to prevent glare
Phoenix Terrace Expressway:
Double-layer blue resin panels with UV-etched interchange structures
Bridge piers manually aged to simulate concrete weathering effects
Dynamic lighting effects system
Traffic simulation: Magnetic-controlled tracks densely populated with 0402 surface-mount LEDs, programmed to achieve bidirectional light particle flow
Hub prompts: East Station node equipped with breathing-style light rings, brightness gradually changing with the demonstration phase
III. Airport Cluster Construction
Airport Component Precision Engineering
Runway System:
2mm aviation-grade aluminium plate etched navigation markings
Embedded micro-light guides simulating indicator light sequences
Terminal Complex:
New Airport: Mirror-finished stainless steel etched architectural framework, UV-transferred glass curtain wall texture
Beixiang Airport: Gradient blue roof thermoformed, laser-welded support structure
Fenghuangtai: Red copper-etched ridge decorative components, chemically passivated for an antique copper finish
Suspended signage system
Conical signage:
White acrylic five-axis precision-carved cones
Magnetic suspension base enabling 15° self-rotation display
Hidden COB light panels at the base creating a soft glow
4. Professional colouring and texture enhancement
Colour engineering
Highway network:
Main road: Hot-melt amber resin frost effect
Ramp: Fluorescent blue night-glow coating
Terrain rendering:
Sunny slopes: Iron oxide red wet spray colour transition
Shaded slopes: Graphite powder dry sweep to enhance three-dimensional elevation differences
Trace restoration:
Toll station area: Silver powder paint simulating brake mark wear
Riverbank edges: Green rust powder mixed with resin to simulate water stain deposits
