Hazardous area classification
Zone drawings and volumes from release sources.

Screenshots and a short video come with the listing (AL.3).
Overview
Planned. This add-on is not built and no host app mounts it. Hazardous area classification is planned (roadmap row CH.17) to turn release sources on the P&ID into zone extents, then into zone drawings in CadCraft (plan and section) and volumes in BimCraft, so the drawings follow P&ID changes. The roadmap calls it an open field with few dedicated tools. A library exists in the lab; no app uses it yet.
Who it’s for
- Electrical and process safety engineers who classify areas.
- Drafters who produce zone drawings.
What you can do
- Nothing works yet. Planned: release sources with grade and ventilation, zone extents, plan circles and section chords on zone layers, 3D volumes, and a check of equipment placed in a zone (CH.17).
Methods and standards
Planned by clause from IEC 60079-10-1 and API RP 505. The library today uses a simplified screening rule that says it is not the standard's table; real tables are meant to be entered as a classification pack by a person with the standard open.
Data and sources
A classification pack (cadcraft-area-pack) typed from the standard by a person. None is bundled. Gas group and temperature class are stored as text only.
Verification
Planned: no add-on test yet. The engine library behind it has a test, tools/process-test/test-safety.mjs, which the session log chem-safety_PART_3 records as 151 passed, 0 failed on 2026-10-28. It checks the library's arithmetic and file handling, not an add-on, and not against a worked example from a published guideline. The checks cover the library's shapes and arithmetic, not any standard's table.
Limits
Not built: the standard's outdoor chart distances, enclosure, pit and trench volumes, dust classification (IEC 60079-10-2), and the drawing commands. Classification is the responsibility of the engineer.
Files and formats
Planned: zone layers in DWG and DXF drawings, and 3D volumes in the model. Nothing is written today.
Get started
- Nothing to open yet. The add-on is planned and cannot be added.
- Watch the roadmap row named in this listing for when it is built and enters the lab.
