AI for facades: from visual options to checked panel schedules

Keep visual choices connected to the elevation

An architect may use AI to explore finish combinations, organize material information and identify mismatches between elevations and schedules. The work becomes useful when each result can be traced to approved geometry and a specific revision.

For a visual study, hold the openings, entrances, storeys and building edges fixed. Compare one design variable at a time, such as joint rhythm or the distribution of finishes. Overlay each returned image on the approved view to check that it still represents the same building.

Record which choices were accepted: finish mark, extent, colour reference and approval status. A screen image does not establish the purchased product's texture, reflectance or colour under actual lighting. Connect the material sample and decision record to the same finish mark used on the drawings.

Define a layout rule before generating panels

Panelization is a geometric task with constraints: datum lines, nominal module, joints, edge clearances, allowable infill sizes and priorities around openings. List corners, reveals, movement joints, parapets and penetrations separately. A repeating pattern alone does not resolve them.

Use a parametric tool or a checked script for repeatable geometry. A language assistant can help formulate the rule, explain exceptions or process the output table. A configured CAD connector may execute supported actions, but its actual selection and changes still need review.

Ask for unresolved regions instead of allowing the system to stretch a final panel to fill a gap. The architect may need to move a datum, change a module or redesign a corner. That decision should remain visible.

Worked example: close a simple dimension chain

Consider an illustrative strip 6000 mm wide. It contains ten equal panels, nine internal joints of 10 mm and two edge clearances of 15 mm. There are no corners or openings in this simplified strip, and these values are not product recommendations.

Using the supplied 6000 mm clear strip, calculate ten equal panel widths with nine 10 mm internal joints and two 15 mm edge clearances. Return the inputs, calculation and closure check. Do not choose a stock product or round individual widths. Flag any ambiguity about the faces defining the strip.

The available panel width is 6000 − 90 − 30 = 5880 mm. Dividing by ten gives 588 mm per panel. The check is 10 × 588 + 9 × 10 + 2 × 15 = 6000 mm.

Next verify that 6000 mm was measured between the faces to which the clearances apply, rather than between opening centres. Then check whether the proposed dimensions are manufacturable and supported by the selected system. Correct arithmetic does not establish either condition.

For a real elevation, request panel boundary coordinates, type marks and an exception list. Independently check a regular bay, an opening and a corner. After an opening moves, confirm that changed panels and schedule rows match the affected region.

Reconcile marks, areas and products separately

Compare elevation assignments with the finish schedule using agreed keys. A description such as “metal panel” is too broad if several finishes, coatings or colours exist. Preserve original strings beside any normalized comparison key.

Return four useful exception lists: marks absent from the schedule, schedule rows with no placement, one mark with conflicting properties, and surfaces counted twice. Include the source row and elevation location for every finding.

Distinguish projected elevation area, actual cladding surface and fabrication material. Define deductions for openings, treatment of reveals and returns, and exclusions belonging to another trade. Panel counts require type and size information; they cannot be recovered reliably by dividing area by an assumed nominal module.

Likewise, a support-system specification is not a finish-area table multiplied by a typical consumption rate. Check it against the actual layout and engineering information supplied by the responsible specialist.

Review interfaces with the relevant documents

At an opening, review the elevation, section and detail together. Check material names, thicknesses, references and the continuity described by the documents. A matching detail number establishes a connection in the package; it does not demonstrate the detail's technical performance.

Use the project's actual jurisdiction, adopted sources and selected system evidence for fire or other performance questions. Do not infer whole-system suitability from a single material description. Keep unresolved applicability questions with the relevant reviewer.

If a PDF is the only drawing source, establish whether it contains vector geometry or a scan. Autodesk's PDF import documentation describes the limits of recovering CAD information from PDF. Any reconstructed elevation needs separate geometric acceptance.

Use ARAI for a bounded drawing check

Prepare a facade drawing-inspection request. Attach a supported DWG/DXF, or export the required Revit view and matching PDF first. Specify units, objects and expected evidence. Review the unsent draft; the request establishes a drawing task, not a promise to design the facade system.
