3DA - 3D Scanner

How much paint do I need for this room? Read your selected 3DA evidence in ChatGPT and calculate paint with confirmed coats, paint-label coverage, allowance and opening deductions. Replies default to feet/inches, square feet and US liquid gallons/quarts; explicit metric requests are honored. The default paint scope is all supplied walls plus an explicitly assumed flat ceiling matching the usable floor area. Missing or irregular ceiling evidence needs clarification. Calculated volume and rounded whole-can quantities are distinct; measurements and coverage remain approximate.

Get 3DA scan data opens the verified Apple listing. Tap Open if offered, or open the installed app manually. In 3DA choose a saved room → Share → Compressed Scan Data → Share Selected Files → Copy in the iOS share sheet. Return manually to this ChatGPT conversation → Paste → verify the ZIP file attachment → Send. Copy Prompt copies text. If Copy does not attach the file, use Save to Files and ChatGPT's attachment menu. Direct sharing to ChatGPT may start a new chat. No automatic capture, file retrieval, clipboard reading or return is provided.

Calculate using ChatGPT is the primary panel action. ChatGPT reads accessible selected evidence and verifies arithmetic before presenting one consistent result. This path does not automatically send measurements to 3DA. General measured-room questions remain available. Attachment and parsing support depend on the ChatGPT client and available tools; a filename does not prove access. Inspect actual export contents and distinguish measured geometry from representative models. Do not assume opaque RoomPlan/USDZ parsing or guaranteed PLY inclusion. No native update or development-only export is required.

Calculate with 3DA instead is an optional collapsed calculator. After disclosure and authorization, it validates supported RoomSummary measurements and computes room basics and paint. Only selected dimensions, relative geometry/transforms, confidence and confirmed paint inputs go to 3DA for in-memory processing. ZIPs, photos, room names, filenames and file links remain outside this request. Our application does not save these measurement payloads/results or pair accounts; OpenAI storage and hosting-provider handling are separate. See https://3da.app/privacy/.

The optional MCP request supports up to 12 KiB of measurement JSON within a 16 KiB RPC envelope, 32 records per category, and eight floor polygons with up to 128 corners each. These are measurement limits, not ChatGPT ZIP attachment limits. No server file picker or archive-upload tool is offered. Its supplied-geometry validation does not prove physical accuracy or complete capture. Wall height is not a measured ceiling height. Verify critical dimensions and paint-label inputs before buying. Observed successful arithmetic tests do not guarantee every future ChatGPT answer.
