The drawing editor
The toolbar, sheet sizes and layer toggles on each of the plant designer's two drawing canvases, plus importing a DXF or KMZ/KML background.
Plant Layout and Single Line Diagram each have their own drawing canvas and toolbar. Because the canvases are independent, the active tool, undo history, snap/ortho state and layer visibility on one do not affect the other.
Drawing tools
The first toolbar row holds the drawing tools, mutually exclusive — one is active at a time, and the active one is highlighted. ▷ Select is active by default.
| Tool | What it does |
|---|---|
| ▷ Select | Selects an element |
| ✥ Move | Moves the current selection |
| ✋ Pan | Pans the canvas |
| ╱ Line | Draws a line |
| ▭ Rect | Draws a rectangle |
| ◯ Circle | Draws a circle |
| ⬡ Polygon | Draws a polygon |
| T Text | Places a text label |
| 📏 Measure | Measures a distance |
| ⟺ Dimension | Places a dimension |
| ⟳ Rotate | Rotates the current selection by 90° immediately, rather than staying armed as a persistent tool |
| ✎ Edit Text | Edits the current selection's text immediately, rather than staying armed as a persistent tool |
Copy, undo and canvas controls
The second toolbar row:
| Control | What it does |
|---|---|
| ⧉ Copy | Copies the current selection |
| ⎘ Paste | Pastes the copied selection |
| 🗑 Delete | Deletes the current selection |
| ↶ Undo | Undoes the last action |
| ↷ Redo | Redoes the last undone action |
| ⤢ Fit | Fits the whole drawing into view |
| ⌗ Snap | Toggle, default on |
| ⊾ Ortho | Toggle, default off |
| 📁 Import | Imports a DXF or KMZ/KML background — see below |

Sheets
A size combobox — A0 / A1 / A2 / A3 / A4, default A3 — sets the drawing sheet's paper size. 🗏 Add Sheet frames the current drawing's bounding box with an ISO A-series sheet border and a bottom-right title block, added on its own layer so it exports with the drawing.
Layer toggles
Six layer toggles control what's visible on the canvas, all default on: equipment, connections, sketch, text, import, sheet.
Importing a DXF or KMZ/KML background
📁 Import opens a file picker filtered to .dxf, .kmz and .kml
files, then reads the chosen file using the form's Latitude and
Longitude fields as the georeferencing anchor. Imported entities land on
the import layer, which is force-shown, and the canvas zooms to fit.
- DXF — units are auto-scaled to metres from the file's own unit setting. Lines, polylines, circles, arcs (tessellated to a polyline) and text entities are read; the drawing is shifted so its bounding-box corner sits at the origin.
- KMZ/KML — every coordinate list in the file's first KML document is projected from WGS84 to local metres, centred at the form's Latitude and Longitude, then shifted to the origin the same way as a DXF import.
