Actual part geometry is shown with a solid outline while the dashed rectangle is the conservative packing envelope. V1 still packs trapezoids by bounding box, so it is not polygon-optimal nesting. Material % measures actual part area; envelope % is the space reserved by the algorithm.

Operation & welfare
How to use the model in winter
Construction alone is not enough. Placement, moisture, bedding, weather and routine inspection directly affect real-world shelter performance.
This is an auxiliary outdoor shelter, not a substitute for keeping a dog indoors during dangerous cold or severe weather.
The shelter should remain dry, protected from direct drafts and raised from cold or wet ground.
The dog needs enough room to stand, turn and lie normally, while excessive interior volume makes heat retention harder.
Regularly check water, bedding, moisture ingress and entrance condition.
During extreme cold, snowstorms or freezing rain, safe indoor shelter takes priority.
Ventilation should limit excess humidity without creating a direct local draft. The PROVISION zone only coordinates location; the actual vent insert requires real-use verification.

0 / 9steps completed
Build the raised base
Assemble the compiled grid of vertical supports and horizontal runners. Use a suitable isolation foot/pad below each support to keep timber off wet ground; adapt anchorage and bearing details to the actual site.
Assemble the insulated floor
Enclose the insulation between lower and interior floor panels so the animal cannot access it.
Assemble walls to the compiled joinery plan
Front and rear walls remain full width while side walls fit between their inner planes. Use the compiled side lengths/heights and entrance dimensions; do not extend side panels through the corner zones.
Weather-protect the four exterior corner edges
Install compatible exterior corner trim/sealing over the vertical joints so cut panel edges are not exposed to water. The selected trim and overlap must follow the exterior finish system.
Reserve the high-rear ventilation insert zones
Transfer the compiled PROVISIONAL zones to the rear wall and keep them clear of studs. Do not cut the final opening until a specific adjustable vent insert is selected; its cutout and net free area are product-specific.
Install insulation and interior linings
Dry-fit the XPS, enclose it with the interior linings and confirm that no insulation edge is accessible to the animal.
Install roof and waterproofing
The roof falls from front to rear, making the rear edge the natural runoff edge. Select a roofing system that explicitly permits the compiled slope, follow its layer/overlap instructions and detail edge/drip protection so water sheds behind the shelter, away from entrances.
Install a compatible purpose-built heating product
Follow the heating product manufacturer instructions; mains adapters and unprotected connections do not belong in the animal space.
Perform the final safety inspection
Check stability, sharp edges, water ingress, ventilation, entrances and interior dryness.
