Help & getting started

Opening PDFs, setting scales, saving files, and keyboard shortcuts.

Your first drawing

  1. Open a PDF from your computer, or drop it into the workspace.
  2. Choose AEC for construction tools, or Simplified for everyday reading. You can change this in Settings.
  3. For measurements, set the page scale first. Use a known dimension when the printed scale is uncertain.
  4. Choose a tool, place your markup, and use Properties to change its appearance.

Browser & desktop

The browser editor uses local PDF processing. A current desktop browser works best; large drawing sets depend on the device’s available memory.

Browser beta. Clipboard, downloads, and keyboard shortcuts depend on browser permissions and reserved keys. Mobile use and full browser parity are not promised.

Saving your work

In a browser, Save downloads a copy. Confirm that it appears in your Downloads folder before closing. Local drafts are recovery aids, not cloud backups; clearing browser data can remove them.

PDF annotation appearances are designed to travel with the file. Advanced measurements, formulas, and custom tool behavior can differ between PDF applications.
