Element Groups

Element groups allow you to organize BIM elements into logical collections based on configurable rules. Groups update dynamically as elements change.

Overview

Element groups provide a way to categorize and filter elements beyond classifications. You can define groups using property conditions, element categories, or other criteria. When elements match the group's rules, they are automatically included.

Creating an Element Group

1. Navigate to Element Groups in the admin sidebar
2. Click Create
3. Configure the group:
4. Name - A descriptive name (e.g., "Exterior Walls", "Load-Bearing Elements")
5. Description - Purpose of the group
6. Grouping Rules - Define conditions that determine group membership

Grouping Rules

Rules use a condition-based system to match elements:

Field	Operators	Example
category	eq, in	Category equals "IfcWall"
properties.*	eq, ne, gt, lt	Fire rating > REI60
classification	eq, in	Classification code starts with "21"

Multiple conditions can be combined with AND/OR operators.

Managing Groups

From the element groups list, you can:

• View Members - See which elements belong to the group
• Edit - Modify the group name, description, or rules
• Delete - Remove the group

Use Cases

• Safety grouping - Group elements by fire rating or structural classification
• Phase grouping - Group elements by construction phase
• Discipline grouping - Group by architectural, structural, or MEP discipline
• Custom reporting - Create groups for specific reporting needs

Permissions

Creating and managing element groups requires write access to the project.
