Build a House and Rear Soffit Enclosure — editor preview
Editor preview: this recording includes features that are not yet released in the public editor. Create a house shell and rear soffit enclosure from blank. Attach the upper frame to the fascia, complete the framed openings, sloping ends and wall returns, then connect separate access units and an outside NPU before exporting.
Before you start: A fictional software demonstration recorded in the development editor. Preview features may differ from the live editor. British male AI narration and English captions. Site-specific design checks are still required.

0:00Build from an empty drawing
This fictional example starts with a blank drawing and builds a bungalow with an enclosure along its rear soffit. Choose Structure and Room to create the footprint, then use Selected to enter the building dimensions. Here the footprint is seven metres by five metres, with walls two point seven metres high. The front entrance will remain clear while the enclosure sits at the back. We will add the roof edge, supporting frames, sheets and equipment, then inspect the model and export the drawing.
0:33Define the roof and soffit
Set the roof to Gable, with a thirty-degree pitch and a tiled covering. Enter the overhang and enable the fascia and soffit. Select the rear eave run and mark that run as the example A I B soffit. The colour is a drawing designation for this fictional job, not a diagnosis of an actual material. Add the door and windows to make the building easy to recognise. Switch to three D to see the roof shape and the relationship between the building and its edges.
1:06Attach the continuous upper frame
Back in the plan, draw a lean-to frame along the rear elevation. Enter its width, depth and lower height. Set the frame's top host to Fascia and choose the bungalow's rear eave. The selected roof edge controls the upper attachment height. With the open-front option enabled, the continuous upper frame can work with separate front sections. Choose the roof face under Sheet this frame, then add sheeting. It follows the chosen frame surface, so the host frame remains the place to adjust its geometry.
1:42Complete the supported boundary
Add separate goalposts at the airlock and baglock positions. Each opening receives a supported upper panel. Build the remaining front sections, including a clear panel for the NPU intake. At each end, set the frame's Top height difference to follow the roof slope, and connect the end sheet to the matching edge of the roof sheet. Finish with a three-hundred-millimetre return to the house wall at both ends. These short returns, upper panels and sloping ends complete the modelled boundary. Inspect their connections in three D before using the drawing.
2:20Place separate access and extraction
Draw the rear soffit enclosure zone and select Outline only in three D, because the physical frame and sheeting are already present. Add a three-stage airlock and a separate three-stage baglock, positioned against their framed openings. Link each to the rear zone. Place the negative-pressure unit outside, at the far end away from the access units. This example uses the fifteen-hundred-class right-exhaust planning model. Its class is not an airflow calculation. Match its actual dimensions and orientation to the adjacent sheet before attempting the connection.
2:59Check the intake and the corners
Select the intake panel, choose the NPU, and use Connect intake opening once the alignment check passes. A connected opening is now visible in the sheet. Orbit around the rear of the house to inspect the equipment and the boundary. The upper panels sit above the access openings, the end closures follow the slope, and the short returns meet the house wall. Check the NPU from the side as well: its intake faces the enclosure and its discharge faces outside. These views make the geometry easier to assess than the plan alone.
3:36Export plan and 3D views
Open Export from the view you want to save. A three-dimensional export uses the current camera angle, so first choose a view that shows the relevant junction. Keep the key in its separate margin and preview the result before downloading. Return to two D, fit the whole plan to the screen, and export the overall layout with its dimensions. The downloaded views show different parts of the same drawing. This complete editor walkthrough was built from blank. It is a fictional software example, with site-specific design and professional checks still required.
