NASJIAI CAD is most useful when the output is editable geometry and the request is specific enough to verify. The difficult part is often not drawing a line: it is retaining the brief, respecting existing elements and checking that the result works. This workflow uses Nasjicad’s selection, agent and CAD tools to keep those checks visible.
1. Establish units, scope and constraints
Before requesting a plan, confirm the units and one measured dimension. Select the actual closed site boundary, not just a rectangular area around it. For an edit, select the elements or area involved and say what must remain unchanged. A screenshot can explain intent, but a measured boundary is a stronger geometric constraint.
Give the room list, priorities, known entrance edge and any confirmed setbacks. State unknowns as unknowns. Do not let an assumed scale or an invented setback quietly become a project requirement.
2. Ask for a layout before detailed furnishing
For an irregular plot, first review whether the room program can fit. Check useful room depths, door connections and circulation. Acute corners may suit open space or storage better than a bedroom. Furnishing an unusable room makes it look more complete without solving the underlying problem.
Example request
Use the selected closed boundary in metres. First propose a layout with an entrance, living room, kitchen, two bedrooms and a bathroom. Keep all built geometry inside the boundary. Show room areas and a continuous route from the entrance to each room. If the brief cannot fit, explain the conflict before reducing any room requirement.
3. Separate the drawing into reviewable tasks
Once the arrangement works, add walls and openings, then furniture, then dimensions and annotations. Request dedicated layers such as A-WALL, A-DOOR, A-WIND, A-FURN and A-ANNO. These are suggested project conventions, not a claim of compliance with a particular drafting standard.
Use library blocks where suitable, then check their units, view and insertion scale. For custom geometry, ask the agent to describe the design assumptions. An elevation or section should be checked against its source plan; selecting the right cut is only part of the job.
4. Check the drawing rather than the explanation
Inspect the result at both overall and detail scales. Use measurements and visible geometry to check the important constraints. If the agent reports a remaining fault, ask for a targeted correction that preserves the satisfactory work.
- Boundary: are the walls, openings and relevant projections within the permitted area?
- Access: can you reach every intended room without passing through an unrelated private room or fixture?
- Operation: can doors open and can furniture and equipment be used without collisions?
- Consistency: do symbols match the legend, and do sections/elevations agree with the plan?
- Delivery: are units, layers, dimensions, labels and the saved output usable by the recipient?
5. Repair locally, then save and reopen
Select a problem area and identify the exact correction. For example, move the basin and its label while preserving the walls and other fittings. Recheck that location and adjacent clearances. Rebuilding the whole plan for a small fault can introduce new mistakes elsewhere.
Save a separate revision and reopen it before handoff. AI drafting does not establish structural adequacy, code compliance or approval for construction. Use the relevant project requirements and professional review for those decisions. Nasjicad’s manual editing remains available; AI is an optional paid service, so start with a bounded task whose result you can assess.
