Look things up.
Read-only tools — they never touch the model, so they're always safe to fire off mid-thought. Answers come back in the pane as lists and counts.
List anything
Levels, views, sheets, schedules, grids, worksets, wall types, family types, view templates, view filters — all listable by name.
When: orientation, or before a change — checking a type name exists before you swap to it, a level name before you build on it.
Inspect one element
Every parameter of a single element — instance and type, as one readout.
When: "what is this thing?" — checking values before a bulk change, or chasing why one element behaves differently.
Find elements by condition
Search a category by type name, level, or any parameter condition — combine conditions with AND/OR, numeric or text.
When: building the set you're about to change or check. Pairs naturally with select, colour, or set-parameter as the next command.
Returns up to 50 matches at a time.
Find what's missing
Elements in a category with no value for a parameter — empty or absent, instance or type.
When: QA passes before a deadline. The classic: doors without a fire rating, rooms without a department.
Count things
Any category, counted and grouped by level, type, or workset. Or the whole model's statistics in one shot — element counts per category.
When: progress checks, sanity checks, "how big is this model anyway".
Material takeoff
Material name → volume (m³) and area (m²), for a selection or the whole model.
When: quick quantity questions without building a schedule first.
Model warnings
Revit's open warnings, with the elements involved in each.
When: health checks before sharing the model — and as the to-do list for a cleanup session.
Where am I, what's selected
Project info (name, number, Revit version, units), the active view and its settings, the elements visible in it, and your current selection.
When: mostly Copilot uses these itself for context — but they answer directly too.
