Layer Maker Course: Formulas In Automations

Automation formulas in Layer let you write conditional logic that computes a result and writes it to a field the moment a trigger fires — not just copy data, but calculate it. In this tutorial, you'll learn how the Calculate a Value action works, why it's fundamentally different from a formula field, and how to chain it with other actions to build genuinely intelligent AEC workflows. The distinction matters: a formula field is always live and read-only. A calculated automation value writes at a specific point in time, which means it works with editable fields and can push data directly to Revit parameters — something a formula field can't do. What's covered: Calculate a Value vs. formula fields — when to use each and why it matters Concatenating room survey notes (floor, base, wall, ceiling) into a single summary on status change Chaining a cost threshold formula: auto-flag work cost estimates above $25K for coordination Cascading actions — trigger emails, create elements, and push to Room Data Sheets from a single automation Where to find the full formula function reference in Layer Docs 📖 Full formula reference: layer.team/docs (look under Formulas) 🎬 More tutorials: layer.team/video 🚀 Start free: app.layer.team/sign-up
