Select the elements, click Create Group on the Modify | Multi-Select tab (or type GP), name the group and click OK. Model elements make a model group; view-specific ones, like text, make a detail group. Edit Group changes every instance at once.
Or, just select the elements and ask Mira to group and name them.
How to do it in Revit
Step 1: Select the elements and create the group
Select the elements in a project view, then click Modify | Multi-Select tab › Create panel › Create Group, or type GP. With one category selected, the tab carries that category's name instead. Name the group and click OK (Autodesk Help: Create a Group by Selecting Elements).
Model elements make a model group, and view-specific elements, such as text and filled regions, make a detail group. Select both and the view-specific part becomes an attached detail group (Autodesk Help: Groups of Elements). Include an existing group to nest it.
Step 2: Attach the tags and dimensions
Tags, dimensions and keynotes can't be grouped without the elements they reference, so they go in an attached detail group. Select the ones that belong to a model group and click Create Group on the Create panel, then name the attached detail group in the Create Model Group and Attached Detail Group dialog and click OK. It appears under its model group in the Project Browser (Autodesk Help: Create an Attached Detail Group).
Step 3: Place more instances
Click Architecture tab › Model panel › Model Group drop-down › Place Model Group, pick the group in the Type Selector and click to place it. For a detail group, start from Annotate tab › Detail panel › Detail Group drop-down › Place Detail Group. You can also drag a group from Groups in the Project Browser (Autodesk Help: Place Groups).
To show its attached detail groups, select the placed model group, click Modify | Model Groups tab › Group panel › Attached Detail Groups and check the ones you want in this view. They show only in the kind of view they were made in (plans, or sections and elevations), never in 3D.
Step 4: Edit once to change every instance
Select any instance and click Modify | Model Groups tab › Group panel › Edit Group (or type EG). The drawing area background changes color in group edit mode. Use Add and Remove on the Edit Group panel, then click Finish. The change reaches every instance of the group (Autodesk Help: Add or Remove Elements in a Group). To edit a nested group, select it first by pressing Tab until it highlights, then clicking.
Step 5: Exclude a member from one instance
When one instance has to differ, such as a wall that overlaps the unit next door, hover over the element, press Tab until it highlights and click to select it. Right-click and choose Exclude: it stays in the group but is hidden in that instance, and Revit tries to rehost anything it hosted. Move to Project on the same menu makes it a normal, editable element instead (Autodesk Help: Exclude Elements from a Group Instance).
To restore every excluded member, select the group and click Restore All Excluded.
Step 6: Ungroup an instance
Select the group and click Ungroup on the Modify | Model Groups tab (or type UG). Its members become individual elements you can edit one by one (Autodesk Help: Ungroup Elements).
The 2026 and 2027 help list Ungroup and Edit Group under a Group button on that tab; the 2025 help shows Ungroup directly on it.
Step 7: Convert a group to a linked model
Select the group and click Modify | Model Groups tab › Group panel › Link. In Convert to Link, choose Replace with a new project file to save the group as a new model, or Replace with an existing project file to link one you already have (Autodesk Help: Convert Groups to Linked Models). Excluded elements come back in the link. The command isn't available in Revit Cloud Worksharing models.
Step 8: Save a group to reuse it
Click File tab › Save As › Library › Group, choose the group in Group to Save, decide whether to Include attached detail groups as views and click Save. From a project it saves as an .rvt file (Autodesk Help: Save Groups). In another project, bring it in with Insert tab › Load from Library panel › Load as Group.
What to watch for
A model group can't hold annotation. A tag you place while editing a model group lands in the project view, not in the group. And Autodesk lets you detach an attached detail group from its model group only if it has no tags or dimensions in it.
Excluded members drop out of schedules. An element excluded from an instance isn't counted in schedules, so excluding a door from one unit takes it off the door schedule.
Duplicate the type when several instances need the same change. Right-click the group in the Project Browser, choose Duplicate, edit the new type and switch instances to it in the Type Selector; the original stays as it was (Autodesk Help: Duplicate Group Types). When you switch, Revit warns about anything that depended on the old group and can't find a reference in the new one.
Nested and mirrored groups need a second look. A nested group is a group type of its own, so Edit Group on it changes every instance of that type, wherever it sits. Before you edit a mirrored copy, read its name in the Type Selector: if it shows the same group type as the original, an Edit Group change reaches both.
Fewer groups, fewer surprises. Autodesk's performance advice is to avoid unnecessary groups, delete unused ones from the Project Browser, and review and fix warnings regularly (Autodesk Help: Model Efficiently). To delete a group, delete its instances first (right-click one instance, choose Select All Instances › In Entire Project, then Delete), then right-click the group and choose Delete.
At firm scale a group's name is what people go by. Typical units, workstations and toilet rooms get copied across the set and saved for the next project, so a group left as Group 7, or a second near-identical type, slows everyone down. Name each group for what it is, such as Workstation A, and check the Project Browser for an existing one before you make another. Mira, the AI agent for Revit, handles the routine part: select the elements, tell it the name, and it creates the group once you approve.
Or, just ask Mira to do it.
Mira is an AI thinking partner for Revit that automates the work you repeat and builds tools your team needs.
- Type this in Mira
Group the desk, chair and monitor I've selected and name the group Workstation A.
Mira tells you what it will group and what the group will be called, waits for your OK, then creates it.
