Project development: 3D design of buildings and terrain

Design the whole development in 3D — pick building type and main form, model terrain with elevation spots, place parking and outdoor areas, and capture images from several angles.

Project development: 3D design of buildings and terrain

In Projektudvikling you design the entire development in 3D — from address to an approved layout with buildings, terrain, parking and outdoor areas. You follow a guided flow, position the buildings on the parcel and capture images from several angles, so the project can be carried forward to sales potential and the report.

1Start from an address

Open Projektudvikling in the left sidebar. The first step in Development is to choose an address — Arcili fetches the parcel and base data automatically.

Search address…

The flow runs in four steps, shown at the top:

AddressTypeSetupSite plan
Note

Once the parcel is loaded, Plot area, Cadastral no. and Parish are shown together with the plan guidelines — Coverage percentage, Max floors, Max height and Free area. These figures are later used to validate the development.

2Choose a building type

In the Type step you choose what you are developing:

Rowhouses
:icon[house]
1-3 floors, private gardens
Apartment building
:icon[building]
Apartments, multiple floors

Confirm with Continue with Rowhouses. Your choice determines which shape parameters appear in the next step.

3Define the main building form

In the Setup step you set the building geometry before the layout is generated. For an apartment building you choose a Building form and Dimensions:

Building form

Rectangle L-shape U-shape T-shape H-shape Curved facade Circular Freeform

Dimensions

Building length · Building depth · Number of floors · Floor height

Under Roof you choose the roof form — Flat roof Pitched roof Mansard roof Hip roof Green roof Roof terrace.

You can let Arcili suggest an optimal layout with Generate layout proposals, or choose Skip proposals and place manually for full control.

Tip

For Freeform you draw the building footprint yourself: click on the map to set points, following the hint "Click on the map to the right to draw the building footprint".

4Place and model in the site plan

In the Site plan step you work in two views. Switch between them in the toolbar:

Site plan3DFacadeFloor planVisualisation

In the left side toolbar you find the drawing and placement tools, grouped:

Tools

Measure measure distance on the parcel Draw path / road · area · waste area Objects parking spot · cycle rack · canopy · trees Terrain place terrain regulation (PG elevations)

Model the terrain

The terrain tool lets you place elevation spots to raise and lower areas — for example for drainage and fall toward the road. In the terrain tab you see Excavation, Fill and Net, and can switch the Elevation display between FF EG DVR90.

Important

Points that deviate more than the allowed limit from the existing terrain are flagged under BR18 §3.1.4 — neighbour notification may be required. Watch for the warning in the terrain tab.

Use Z to undo and Z to redo.

5Capture images from several angles

Once the layout is in place, you capture the project from several angles. Arcili stores the images in named slots:

Your perspective
:icon[camera]
Your current camera angle
Corner SE/SW
:icon[box]
Auto-positioned corners
Corner NW/NE
:icon[box]
Auto-positioned corners
Site plan
:icon[map]
Top-down from the map

Switch to 3D and set the camera before capturing Your perspective. The corners and bird's-eye view are positioned automatically, and Site plan is captured from the top-down view. Finish with Next: Sales Potential to carry the images forward.

Note

This part is built for desktop (screen ≥ 1024 px), where the 3D editor and toolbars have room. Use a computer for the design work itself.
