Shapes

Mark equipment zones, room areas, and site boundaries.

Overview

Shapes allow site teams to define specific boundaries and zones.

  • Cloud: Highlight revision areas and change zones.
  • Rectangle: Mark equipment footprints and room boundaries.
  • Ellipse: Circle specific components or regions.

Quick Examples

Activate shape tools with the `toolControl` message.

Cloud

iframe.contentWindow.postMessage({
  type: 'toolControl',
  payload: { group: 'drawing', action: 'SHAPE_CLOUD' }
}, viewerOrigin);

Rectangle

iframe.contentWindow.postMessage({
  type: 'toolControl',
  payload: { group: 'drawing', action: 'SHAPE_RECTANGLE' }
}, viewerOrigin);

Ellipse

iframe.contentWindow.postMessage({
  type: 'toolControl',
  payload: { group: 'drawing', action: 'SHAPE_ELLIPSE' }
}, viewerOrigin);

Deactivate

iframe.contentWindow.postMessage({
  type: 'toolControl',
  payload: { command: 'clear' }
}, viewerOrigin);

Complete Implementation

Complete workflow: initialize the canvas, load a file, then manage tool activation.

// CONFIGURATION
const VIEWER_URL = 'https://your-canvas-domain.com';
const VIEWER_ORIGIN = 'https://your-canvas-domain.com';
let activeTool = null;

// INITIALIZE CANVAS
const iframe = document.querySelector('[data-viewer-iframe]');
iframe.src = VIEWER_URL;

iframe.addEventListener('load', () => {
  // LOAD FILE
  iframe.contentWindow.postMessage({
    type: 'view',
    payload: { fileUrl: 'https://example.com/document.pdf' }
  }, VIEWER_ORIGIN);
});

// LISTEN FOR EVENTS
window.addEventListener('message', (event) => {
  if (event.origin !== VIEWER_ORIGIN) return;
  if (event.data.type === 'fileInfo') {
    console.log('File loaded:', event.data.payload.fileInfo.name);
  }
});

// TOOL CONTROL
function activateTool(action) {
  iframe.contentWindow.postMessage({
    type: 'toolControl',
    payload: { group: 'drawing', action: action }
  }, VIEWER_ORIGIN);
  activeTool = action;
}

function deactivateTool() {
  iframe.contentWindow.postMessage({
    type: 'toolControl',
    payload: { command: 'clear' }
  }, VIEWER_ORIGIN);
  activeTool = null;
}

function toggleTool(action) {
  activeTool === action ? deactivateTool() : activateTool(action);
}

// USAGE
// activateTool('SHAPE_CLOUD');
// toggleTool('SHAPE_RECTANGLE');
// deactivateTool();
