How to Use the 3D Shed Builder
Follow these seven steps to design your shed and check your openings.
1STEP 1 – Select your wall side
Start with the camera buttons in the 3D preview and select the wall side you want to work on first: Front view, Back view, Left view or Right view. These buttons change the camera view only.
2STEP 2 – Enter your shed dimensions
In the Design your shed panel, choose Imperial (feet) or Metric, then enter the shed length, shed width and wall height. These dimensions set the shed’s overall size. Metric values in this version are displayed in metres (m).
3STEP 3 – Choose your roof
Select a roof style and pitch. Gambrel uses fixed 6/12 upper and 24/12 lower slopes; the other styles use the selected pitch.
4STEP 4 – Add your doors
First choose the Door Wall where the door should be placed. Match the camera view to that wall to inspect it. Then enter the door quantity, choose single hinged or double hinged, and enter the total opening width and door height. The Door Wall selector sets placement; camera buttons only change the viewing angle. For double doors, the opening width is the combined width of both leaves.
5STEP 5 – Add your windows
First choose the Window Wall where the windows should be placed and match the camera view to that wall. Then enter the window quantity, width and height. The Window Wall selector sets placement; camera buttons only change the viewing angle.
6STEP 6 – Inspect your shed in 3D
Select Front, Back, Left or Right to inspect a wall; choose Top view to look down from above. Drag the model with your mouse to rotate and scroll the wheel to zoom. On touch devices, drag or pinch where supported. Choose Reset view to return to the default camera position.
7STEP 7 – Check your opening placement
The placement summary beneath the preview reports doors and windows requested and placed, plus any omitted openings. Read the summary and inspect each wall to confirm openings are where you expect.
