Case study on the production of urban planning sand table model

1、 Preliminary preparation: the "first level" of precise restoration

After receiving the urban planning sand table order from Xuhui District, we first conducted on-site research and used drones to record terrain undulations and river directions. Then, we combined the planning drawings to sort out the layout of roads, buildings, and green spaces. The team repeatedly compares the logic of "real scene → blueprint → model" to ensure that every detail is based on evidence - such as the winding direction of rivers and the shape of green spaces, which must correspond to reality one by one.

2、 Material selection: Make the model "textured"

Topographic base: choose environment-friendly foam board as the base plate, which is light and easy to process;

Main body of the building: Cut the building outline with PVC board, and then stick acrylic board to make the exterior wall, simulating the transparency of the glass curtain wall;

Road system: Dark gray resin is used for asphalt roads, and light gray PVC is selected for cement roads to restore the true texture of the road surface;

Vegetation coverage: simulated lawns (green series) are used for green spaces, resin trees (simulated trunk texture) are used for trees, and small shrub models are used to enrich the layers;

Water performance: The river uses blue resin and reflective film to simulate the luster of the water surface; The lake is made of deep blue resin, highlighting the differences in water depth.

3、 Production process: the transformation from "flat" to "three-dimensional"

Terrain shaping:

First, use hot melt glue to pile up the ups and downs of mountains and river trends on the foam board, and then use sandpaper to polish the edges to make the terrain transition natural.

Building assembly:

Cut the PVC board according to the drawing ratio, paste it into the building outline with hot melt adhesive, then paste the acrylic board to make the exterior wall, and finally polish the joints with fine sandpaper to make the building stand firmly and look real.

Road paving:

Plan the road direction according to the blueprint, use resin/asphalt materials to paste in sections, and then use a carving knife to mark the lane lines, so that the road can "walk" smoothly and "divide" clearly.

Vegetation planting:

First, lay a simulated lawn in the green area, then insert resin trees and place small shrubs to simulate natural distribution; Trees are fixed with hot melt adhesive to ensure stability and prevent tilting.

Water body construction:

Fill rivers and lakes with resin, and then apply reflective film to simulate water surface gloss; Polish the edges of the river with sandpaper to make the water flow naturally.

4、 Post processing: Bring the model to life

Coloring and Details:

Use acrylic paint to color the exterior walls, roads, and vegetation of buildings, and then use fine pens to outline the building contours and road markings, making the colors "accurate" and "fine".

Lighting Design:

Embed LED light strips at the top of buildings and below roads to simulate nighttime lighting effects; Adjust the brightness with a controller to make the model "bright" with layers.

Overall adjustment:

Repeatedly check from different angles, adjust the location of buildings and vegetation density to ensure a 90% restoration degree - such as the slope of mountains, the curvature of rivers, and the arrangement of buildings, all of which should be "lifelike" to the real scene.

5、 Delivery acceptance: Customer's' satisfactory answer sheet '

After the model is completed, we invite the client to conduct on-site acceptance. The customer stood in front of the model, pointed to a building and said, "Here is exactly the same as in reality.
