This guide shows how to use the Snaptrude Agent for a commercial interior or workplace fit-out. The agent can trace the base building from a CAD file or PDF, build the space program from a headcount brief, test-fit layouts, place workstations, meeting rooms and amenities, add doors and furniture, and produce area tables and presentation sheets. Use it for office test fits, tenant improvements, coworking floors and other commercial interiors.

Before you start

Open the AI chat with the Agent button at the top of the far-left rail. Type in the Ask anything box. Use Attach files (image, PDF, or text) to give the agent a brief, an RFP or a reference image, and Redline this view to mark up what you want changed.
The agent works in Design, BIM and Present Mode, and can read your Program Mode sheets.
Steps that create BIM objects (walls, doors, windows, stairs, families) need BIM Mode, which is included in the Pro, Organization and Enterprise plans.
Every prompt uses AI credits. For long, multi-step jobs, open Boosts under the chat box: Fast mode runs up to 5x faster and uses 2x credits; Cloud processing keeps tasks running in the background.

1. Bring in the base building

Most interior projects start from an existing floor plate. Click the project name, choose Import, and pick CAD Files (.dwg) or PDF. Then ask the agent to trace it.

Try: "Trace the imported base building PDF for level 12: create the exterior walls, core walls, columns, windows, stairs and lifts. Treat the core as fixed."

Tip: Select the import and lower its Opacity in the Properties panel so you can see the traced walls clearly.

2. Build the program from the headcount brief

Try: "Read the attached brief and build the program: 180 people, 70% desk ratio, 12 meeting rooms in a mix of 4, 8 and 12 seats, 2 boardrooms, focus rooms, a café, reception, IT and storage."

Review the program in Program Mode (it opens in its own browser tab) and adjust targets before laying out the floor.

3. Test-fit the floor

Try: "Test-fit the program on the level 12 floor plate. Put workstations along the windows, meeting rooms and focus rooms against the core, reception and the café near the lifts, and keep a 1.5 m primary circulation loop."

Try: "Create a second option as a new design proposal with a more open plan: fewer enclosed rooms and more collaboration space."

Tip: Use Smart Layouts (on the canvas toolbar at the right edge) for repeating room layouts such as meeting rooms and workstation clusters.

4. Add doors, glazing and furniture

Try: "Add doors to every enclosed room, glazed fronts to the meeting rooms, and furnish the floor: 126 desks with chairs, tables and chairs in each meeting room, a reception desk, and café seating for 40."

Try: "Swap the desks in the north zone for 1.6 m benching and add lockers next to the core."

5. Check areas and headcount

Open the Areas tab in the right panel to check usable area by space type, or ask the agent directly.

Try: "Summarize the plan: total desks, seats per meeting room, area per person and how close we are to the program targets."

6. Present the test fit

Try: "Place the furnished floor plan and a 3D view on this sheet and add an area table."

Click an image on a sheet to open AI Inspirations for interior mood renders. Export from Present Mode with Export, as PDF, PNG or JPG.

Note: The agent gives you a strong starting point, not a finished, code-checked design. Review every result: check dimensions, clearances, egress and local code requirements with your own professional judgment before you rely on it.

Tips for working with the agent

Work in steps. Ask for one stage at a time (site, program, massing, plans) and review before moving on. It's easier to steer than one giant prompt.
Be specific about numbers: areas, counts, floor-to-floor heights, setbacks and grid sizes.
Say what must stay the same: "keep the core and the structural grid, only change the unit mix".
Use Redline this view to sketch over the model when describing a change is harder than drawing it.
Start a fresh conversation with + (Start a new session) when you switch to a different design question. The agent's Memory (in the ... menu) keeps preferences you want it to reuse.
Use Design Proposals to keep alternative schemes side by side instead of overwriting one option with the next.
Give the agent your client's standards up front, such as desk size, meeting room sizes and finish palette, and save them to the agent's Memory so every test fit follows them.
