Draw a Bay-Window Hallway and Understairs Enclosure — editor preview
Editor preview: this recording includes features that are not yet released in the public editor. The hallway is shown as a roof-hidden cutaway; the upper stair opening remains under review. Draw a bay-window hallway, fit a native understairs cupboard and identify the separate inner-door and sloping-ceiling AIB linings. Add the partition, separate access units and an outside exhaust route, then inspect and export the cutaway.

0:00Draw the bay-window hallway
This fictional drawing places an understairs cupboard within a bay-window hallway. Start from an empty plan and draw the connected room perimeter, including the angled bay returns. Attach the windows to the three bay faces and add the entrance at the south end. The hallway provides context for the cupboard and the approach to the work area. Keeping that surrounding room in the model helps explain where the enclosure and access equipment sit. The dimensions in this demonstration are illustrative.
0:33Fit the native understairs cupboard
Choose Normal Staircase from Assets and set the flight's width, run and rise in Selected. Check its direction in the plan. Enable Enclose beneath stairs to create the fitted cupboard beneath the straight flight. Choose the door side facing the hallway, then set the opening and swing. The door fits within the height available beneath the stair slope. This model is being reviewed as a roof-hidden cutaway. Hiding a ceiling is a viewing control; it does not create a physical stairwell or establish an upper landing.
1:09Identify the two example AIB linings
Enable A I B lining on inside of door and A I B panel beneath stair slope separately. The first marks the inner face of the cupboard door; the second marks the sloping ceiling beneath the flight. Open the cupboard door to expose the inner lining. For the sloping surface, the underside inspection view lets us look up beneath the stair. Temporarily hidden context layers make that surface visible. This is an explicit inspection cutaway, not a view of a completed stairwell. The red colour identifies the example material in the drawing.
1:47Build the surrounding enclosure
Draw the enclosure zone beside the cupboard, leaving the hallway entrance and approach visible. Build the partition from separate frames, with distinct openings for the airlock and baglock. The small north infill is two hundred and three millimetres wide. Add the upper panels above both access openings and the remaining full-height sections. Use Add sheeting to face so each sheet follows its supporting frame. The final section is a panel for the NPU intake. Keep the equipment at its intended size and adjust the surrounding layout to accommodate it.
2:25Connect the access equipment
Add a three-stage airlock and a separate three-stage baglock. Enter their position and rotation so their enclosure ends meet the framed openings. Assign both runs to the understairs enclosure zone. Place the negative-pressure unit outside the enclosure at the far end, away from those access connections. Select the clear panel and connect the intake only after the editor accepts its alignment. Check the cupboard door swing, the hall entrance and the access runs together. The plan should explain the approach as well as the enclosed work area.
3:03Route the exhaust outside
Use Route and Ducting to draw the discharge route from the NPU. Edit the route-point heights so the duct rises above the approach before continuing through the west side of the building to outside. Inspect the bends and wall crossing in three D. The route is part of the drawing, rather than an airflow calculation. Use both an elevated cutaway and a close cupboard view: one explains the overall arrangement, while the other shows the door lining and sloping ceiling. Restore the intended context layers after inspecting the underside.
3:39Save the cutaway and overall plan
Return to the plan and fit the whole drawing to the screen. Export the overall layout with its key, then save the cupboard inspection detail as a separate view. Preview each generated file before downloading it. The drawings explain the fictional enclosure position and the two cupboard linings. The upper stair and ceiling opening require their own completed-building review; the current roof-hidden view must remain labelled as a cutaway. This film demonstrates the software controls and does not specify an asbestos-removal method.
