How engines work

Non-destructive by design

An engine is a separate layer saved alongside your drawing. Work in it as long as you like. The plan underneath never changes. Switch engines freely. The plan you drew once feeds every one of them.

Engine documentation
  • Draw once, reuse the same plan
  • Region & standard aware (US / UK / EU / AU)
  • Colour plans by category, switch or zone
  • Images, PDFs and report exports
