For the engineers who actually build it
One canvas, three disciplines.
Process, electrical and automation engineers work side-by-side on the same project. The symbol library knows which variant to render for each drawing type.
// ELECTRICAL
Electrical engineers
Schematic, single-line, power, terminal, wiring, earthing, incomer drawings on the same project. IEC 60617 symbols. Switch the project to UL 508A and wire colours, designators and net labels follow.
Electrical workflow →// AUTOMATION
Automation engineers
PLC drawings with one rack per sheet, auto-generated I/O list. Sensor and relay-board connections, panel-to-panel interfaces. Custom symbol creator for vendor-specific devices.

Engineering features, not just drawing
Built to do the work, not just record it.
The features that turn a 4-tool workflow (CAD + Excel + email + manual numbering) into one tool.
01
Multi-variant symbols
One library part stores up to seven variants — schematic, SLD, three-phase, P&ID, control, panel front, terminal — the canvas picks the right one for the drawing.
02
Switch the standard, project follows
IEC ↔ UL 508A ↔ cUL/CSA ↔ AS/NZS ↔ NEMA. Wire colours, reference designators (K vs CR), net labels and terminal palettes update across every drawing.
03
P&ID lines auto-colour by fluid
Water blue, oil red, air cyan, hydraulic. The pin’s fluid kind on the symbol drives the line colour automatically — no convention to remember.
04
Cable sizer (IEC 60364-5-52)
Enter load, voltage, install method, ambient. Get the cross-section in mm² with the rule it applied — one click to apply to the selected wire.
05
Terminal strips auto-generated
Wherever a wire crosses a panel boundary, the system generates a terminal row with sequential number, IEC/UL wire colour, cable ID and references. No more hand-numbering X1:1, X1:2…
06
PR-style drawing reviews
Request review, approve / changes-requested / rejected, full history. Built for teams who already work this way in software.
07
Read-only share — no login
A /view/<token> link your client opens on a phone. No account, optional expiry.
08
Odoo integration
Sync the parts library from product.product. Push the project BOM straight into Odoo as mrp.bom for manufacturing.
09
Browser-native, no install
Built on Konva.js. Works on any laptop, tablet, and on a phone for read-only viewing. No Java, no plug-ins, no IT ticket.
Drawing types
15 drawing types. One canvas. One symbol library.
All on the same project, sharing the same components and netlist. Add a contactor once; it shows up correctly on every drawing it appears on.
Choose a standard at project creation — the wire colours, designator prefixes and default net labels switch project-wide.
