Carport
The Carport Wizard places a carport structure. Set the footprint size and click to place on the canvas, then configure the roof and posts in the sidebar.
Start the Carport Wizard from the Add Object panel. Set dimensions in the sidebar and click on the canvas to place. The sidebar shows three configuration steps: Roof, Posts, and Apply.
Step 2 — Posts
Set post cross-section size and the number of intermediate posts along the long span.
Set footprint dimensions
In the Footprint section of the wizard sidebar, enter the Width (side-to-side) and Depth (front-to-back) of the carport slab. A standard single-car carport is roughly 3 m wide by 5 m deep; a double-car carport is typically 6 m wide. Click the canvas to place the carport at the desired position, then drag the placement handle to fine-tune the origin.
Choose the roof style
In the Roof step, select the roof type: Flat for a clean contemporary look, Mono-Slope (Shed) for a single-pitch roof that sheds water to one side, or Gable for a symmetrical peaked roof with more central headroom. Adjust Pitch (deg) to control the slope angle and set Front Overhang and Side Overhang to extend the roof edge beyond the posts. The live 3D preview updates as you change each value.
Assign roofing material
Below the roof geometry controls, click the Roof Surface material swatch to open the material picker. Choose a photoreal material such as a metal sheet, polycarbonate, or timber to represent the roof cladding. The Structure Metal swatch controls the color and finish of the posts and beams — click it to match your structural frame to the property's existing metalwork.
Configure post layout
Move to the Posts step. Toggle Enable Posts on to show structural supports. Under Layout, choose Corners to place a post at each corner only, or Sides to add intermediate posts evenly spaced along the front and back edges — useful for wider spans. Set the Post Width and Post Depth to match the cross-section of your chosen structural profile.
Set post and roof heights
In the Height section, enter the Post Height — the clear height from ground to the underside of the roof beam. For a standard vehicle clearance, 2.4 m is the minimum; 2.7 m or more is recommended for larger vehicles. The Roof Peak Height field shows the calculated apex; for Flat roofs it matches the post height, and for Gable and Mono-Slope roofs it adjusts automatically based on the pitch and width.
Grade terrain and apply
If the carport sits on sloping ground, enable Grade Terrain in the Apply step to pad-deform the terrain under the footprint to a flat level, matching the carport slab. Review the full 3D preview in the canvas, then click Apply to commit the carport as a parametric object. You can re-enter the wizard at any time by selecting the carport and clicking Parameters in the inspector.
A Mono-Slope roof is ideal when the carport sits against a boundary wall or building facade — slope the roof away from the wall so rainwater drains outward rather than pooling against the structure.
The wizard adopts any selected rectangle as the carport footprint. Draw your parking bay first using the Rectangle tool, select it, then open the Carport Wizard to skip the manual dimension entry step.
Enabling Grade Terrain flattens the ground mesh under the carport footprint. This is a terrain deformation — if you later delete the carport, use the Terrain workspace to restore the original ground contour manually.
Key Parameters
| Name | Default | Description |
|---|---|---|
| Width | 3.0 m | Side-to-side dimension of the carport footprint. |
| Depth | 5.0 m | Front-to-back dimension of the carport footprint. |
| Roof Type | Flat | Flat, Mono-Slope (Shed), or Gable. Controls roof geometry and water drainage direction. |
| Pitch (deg) | 10° | Roof slope angle in degrees. Applies to Mono-Slope and Gable roofs; ignored for Flat. |
| Front Overhang | 0.3 m | Roof extension beyond the front posts. |
| Side Overhang | 0.3 m | Roof extension beyond the side posts. |
| Post Height | 2.4 m | Clear height from ground level to the underside of the roof beam. |
| Post Layout | Corners | Corners places a post at each corner only. Sides adds intermediate posts along the front and back edges. |
| Post Width / Depth | 0.1 m × 0.1 m | Cross-section dimensions of each structural post. |
| Grade Terrain | Off | When enabled, flattens the terrain under the carport footprint to a level pad. |
Frequently Asked Questions
What roof styles are available for a carport?
Three styles are available: Flat (level roof with a slight drainage slope), Mono-Slope / Shed (a single-pitch roof higher on one side), and Gable (a symmetrical peaked roof). For modern and industrial properties, Flat is common. Mono-Slope suits boundary installations where drainage must flow in a specific direction. Gable provides the most central headroom and suits traditional property styles.
Can I attach the carport to an existing building wall?
The Carport Wizard places a freestanding structure with posts on all sides. For a lean-to shelter attached to a wall — where one side of the roof connects directly to the building facade — use the Covered Patio Wizard instead, which has a dedicated wall-attach option.
How do I edit a carport after placing it?
Select the placed carport on the canvas. In the inspector panel, click Edit to re-open the wizard with all current settings pre-loaded. You can adjust dimensions, roof style, post layout, and materials, then click Apply to update the object. The footprint entity on the drawing is updated automatically.
The carport sits on a slope — will it look right in 3D?
Enable Grade Terrain in the Apply step. This deforms the terrain mesh under the footprint to a flat pad at the placement elevation, so the carport posts sit flush with the ground rather than floating above or cutting into a slope. Without this option, the carport geometry itself remains flat regardless of the terrain.
Can I use a double-car or triple-car width?
Yes — there is no width limit. Increase the Width field to accommodate multiple bays (typically 5.5–6 m for two cars). For wide spans, switch the Post Layout to Sides so intermediate posts support the roof beam at closer centres, reducing the unsupported span.
