P&IDs that are a view of your model

Place from a standards library, tag it once, and every sheet stays the same drawing.

The ErgoPlanner P&ID editor walkthrough: an AI prompt places a pumping station, the layers panel and bill of materials open, the view zooms, the symbol library is searched and the side panels collapse.

What this replaces

The same change redrawn on five sheets, because each sheet is its own file

Nobody can say which drawing is current without asking the person who issued it

A symbol library that drifts from the standard the client asked for

How it works

01Place from a symbol library filed by standard — BS 1553, ISA-5.1, ISO 10628, PIP or IEC

02Tag the equipment and connect it; tag formats are checked as you go

03Sheets and process-area views are both views of the one model, so neither can fall behind it

04Save a named version at a milestone, and restore any earlier one

What you get out

Drawing sheets as PDF, SVG or PNG
DXF — one sheet or a multi-sheet set
Tag register (CSV)
Version register (CSV or JSON)
Drawing register — on screen, one row per process-area view; no file export yet

Drawings, registers and exports are produced from your model as you build it. They are working engineering documents and need a competent engineer’s review before they are issued.

What it is built to

BS 1553 — symbol library
ISA-5.1 — symbol library, and the tag-format validation rule
ISO 10628 — symbol library
PIP — symbol library
IEC — symbol library

Technical capabilities

Symbol libraries, by standardThe shipped corpus is filed into BS 1553, ISA-5.1, ISO 10628, PIP and IEC buckets from the library file it came from, and a symbol carries its standard with it. Rendering a model against a second standard is a Professional-plan capability; a Starter organisation works in one.

Sheets and process areasA sheet view has bounds and a title block; a process-area view is a named set of elements with interface points for the connections that cross out of it. Both hang off the same model, and an element is not copied into either.

Version historyVersions you name yourself — mark a milestone, restore it later, and the restore takes its own backup first. Automatic capture runs alongside it, throttled to one revision every ten minutes and pruned to the last thirty, so it is a safety net rather than a record of every keystroke.

TaggingTags are assigned, validated for duplicates and ISA-5.1 format, renumbered in bulk, and exported as a register. The validation set checks tag format and uniqueness — it does not check a symbol against its standard.

Working togetherEdits merge through a CRDT rather than a file lock, so two people on the same drawing do not overwrite each other, and edits made offline merge when the connection returns. The editor canvas needs a browser with WebGPU.

ExportPDF, SVG and PNG per drawing; DXF for a single view or a multi-sheet set. There is no DWG writer — DWG is accepted on import only.

Questions people actually ask

Is a sheet a file?

No. A sheet is a view with bounds and a title block over the one model, and so is a process area. That is the whole point of the page: there is no copy of the pump on sheet 3 to forget to update, because sheet 3 is a window, not a document.

Can I export to DWG?

Not today. You can export DXF — a single sheet or a multi-sheet set — and PDF, SVG or PNG. DWG works in the other direction: you can import a DWG and we will read it. If DWG export decides a purchase for you, tell us, because that is the kind of thing that gets built.

Which standard do the symbols follow?

Each symbol is filed under the standard its library came from — BS 1553, ISA-5.1, ISO 10628, PIP or IEC — and you pick which library you draw from. Rendering one model against a second standard is a Professional-plan capability.

Does it check my drawing against the standard?

It checks what it can check mechanically: tag format against ISA-5.1, and duplicate tags. It does not decide whether a symbol is the right symbol under BS 1553 or ISO 10628 — that is still a competent engineer’s call, and we would rather say so than imply a compliance check we have not written.

What happens to a drawing I imported from CAD?

It is mapped, not recognised: each block in a DXF or DWG is matched against your mapping table and becomes a tagged element, and blocks with no mapping are kept as placeholders for you to resolve. A scan or PDF goes through recognition instead, and you review every proposed symbol before anything is placed. Import & Recognition has the detail.
