Ever wish your diagrams could tell you when something is out of place? This tutorial dives into the "smart" side of Lucidchart, showing you how to use formulas and conditional formatting to enforce diagramming standards automatically.

What you’ll learn:

  • Data-rich containers: How to assign custom properties (like "ID" and "Type") to containers—such as VPCs—and the individual components within them.
  • Smart formulas: Using the does not contain and contained by formulas to create logic that knows where a shape belongs.
  • Automated coaching: How to trigger alert icons and custom hover text that guides users to move shapes to the correct location in real-time.
  • Control at scale: Leveraging custom shape libraries to maintain consistency across your entire team.

⚙️ A note on the UI

Recorded around 2024, this video features a previous version of the Lucid interface. While the buttons may have a fresh look today, the formula logic and conditional formatting power shown here are still fully supported.
