Session 2 of the Layer Maker Course
This session goes beyond basic fields into the field types that turn a flat list of elements into a connected project model: relationships, formulas, lookups, and rollups.
By the end of the hour, you'll know how to link elements across categories, calculate derived values, surface data from related records, and aggregate up to totals.

What we'll cover
Relationship fields: linking a Door to its Room, a Room to its Finish Schedule, an Asset to its Manufacturer
One-to-many vs. many-to-many relationships, and when each makes sense
Formula fields: calculating areas, totals, percentages, and conditional values from other fields on the same element
Lookup fields: pulling values from a related element into the current one
Rollup fields: aggregating across a set of related elements (sum, average, count, concatenate)
Common patterns: door-to-room schedules, FF&E-to-room rollups, condition-score averages
Who it's for
BIM managers and data leads building schedules and matrices in Layer
Anyone who has used basic text, number, and select fields and is ready to model relationships between elements
Firms migrating from Excel-based schedules where everything is flat and duplication is the cost
If you haven't seen Session 1, the recording covers the foundation this session builds on.
