Issue with Duplicate Names on Cloning & Dynamic 3D Measurements

Hello Verge3D Team and Community,

I am building a modular sofa configurator. Users can add and remove 5 different types of modules. I have encountered a major blocking issue regarding object naming and dimension tracking.

1. The Cloning Name Collision Issue
My current logic for naming clones is based on the count of active modules.

The Problem: If I have modules named corner_1, corner_2, and corner_3, and I delete corner_2, my total count drops to 2. When I add a new module, the logic names it corner_3 again.

The Result: I end up with two objects named corner_3 in the scene.

Console log example: visible : corner_1, corner_3, corner_3
This naming collision prevents me from correctly identifying objects in my “visible modules” list and breaks my measurement calculations.

2. Dynamic 3D Dimensions (L x W x H)
I need to display the overall dimensions of the sofa assembly in the 3D viewport.

It must update in real-time whenever a module is added or removed.

I want to show a line for the total Length, Width, and Height.

I need floating annotations/labels at the center of these lines displaying the values.

My Questions:

What is the best way to implement a persistent global counter for IDs that never resets or decreases, ensuring every clone has a strictly unique name regardless of deletions?

How can I calculate the “Global Bounding Box” of a list of specific objects (clones) to get the overall dimensions?

What is the most efficient way to render these dimension lines and labels so they follow the sofa’s bounds dynamically?

Any advice on the Puzzles logic or small JavaScript snippets to handle the bounding box would be extremely helpful !
