C&K Join & Unjoin

Batch process geometric joins, unjoins, and switch join order between groups of Autodesk® Revit® elements using precise category, family, and type rules.

$2.00/month

C&K Join & Unjoin is a highly optimized batch utility designed to automate the tedious process of joining and unjoining intersecting model elements in Autodesk® Revit®.

Whether you are resolving overlapping structural elements, aligning architectural finishes, or cleaning up complex geometry, this tool allows you to target specific elements with precision, saving hours of manual work and helping eliminate overlapping-volume warnings.

Unlike standard Revit tools, C&K Join & Unjoin lets you drill down from the category level to the family and specific type levels to create custom selection sets. It pre-checks elements for physical intersection in memory before calling Revit's Join API, delivering maximum speed even on large, complex models.

Key Features

Batch Join & Unjoin:Process hundreds of elements simultaneously bydefining two target selection lists (List 1 and List 2).
Granular Tree Hierarchy:Drill down from Model Categories to Families and individual Family Types to target only the elements you need.
In-View Processing:Scans only the current active view, making the selection and execution process fast, predictable, and safe.
Instant Text Search:Easily filter large lists of categories, families, and types in both panels using live text search.
Performance Optimized:Built-in bounding-box overlap checking ensures that the tool only invokes Revit's Join/Unjoin API for elements that physically intersect, helping prevent performance lag.
Smart Join-Order Switching:After joining, the tool automatically evaluates the join priority. If the cutting element is not configured correctly, it automatically switches the join order based on your list hierarchy.
Execution Logs:Generates a detailed text report listing successful joins, failures, and warnings, which can be viewed immediately after completion.
Settings Memory:Automatically remembers your last selected categories and configurations, enabling faster repetitive runs.

Compatibility:Revit 2023, 2024, 2025, 2026, and 2027.

Prerequisites:An active Revit project with an open view.

Frequently asked questions (FAQs)

What else should I know about this product?

Optimized Performance: The app uses bounding box intersection pre-checking so it only attempts to join/unjoin elements that are physically near each other, saving significant processing time on large models.
Scope: Processes elements visible and present within the current active view for maximum control and safety.

Are there any known issues with this product?

Elements must physically overlap or intersect in space in order to be joined.
Only model categories containing physical geometry (such as Walls, Columns, Floors, etc.) are loaded into the trees.
