Hi,
If your work often involves Dynamic Components (DCs), you’ve likely faced the issue where these components automatically rename themselves when their size or attributes change, resulting in multiple DCs of the same type with different names and definitions. I created this plugin to solve that problem. It quickly merges duplicate Dynamic Components, corrects small numerical errors, and cleans up your Definition List with one click, streamlining your design process and keeping your models organized.
It’s FREE.

Try my Replacer at https://community.sketchucation.com/post/1614911 . Perhaps this is something you've been looking for.

NT Replacer is a SketchUp plugin that lets you quickly swap one or multiple entities with another while preserving their materials and layers. It offers three replace modes:

1. Normal Replace – Standard replacement.
2. Scale to Fit – Replacement scaled to match the target’s dimensions.
3. Paste In Place – Replacement pasted into the exact same position.

IT'S FREE! I hope to make a small contribution to help make your work easier!
