Remove duplicate geometry

Anonymous — Tue, 17 Sep 2019 17:14:10 GMT

I somehow ended up with a scene that has most of the geometry cloned on top of each other, in the same exact position. This is quite a large scene so manually deleting will take too much time. I was wondering is anyone knew of a method or script that could delete identical geometry on top of each other. Thank you.

Thanks for posting your question on the 3ds Max forums!

I found this script on Scriptspot, but wasn't able to get it to work at first (I'm a novice with MAXscript).

As @miledrizk notes below, If you run the script, it will add the option to add the script to the toolbar. You can add this script to the toolbar by navigating to Customize > Customize User Interface > Toolbars tab. Under the Group "main UI, search for "Duplicate Geometry Remover", and add it to a new toolbar.

For more information about making Toolbars, see the Learn article: Toolbars Panel.

I hope this helps, talk to you soon!

Hi,

Actually the first script works,

Maybe you tried to run it from the editor, in that case, it will be installed as a new action

Without being executed. You need to add it to the UI by going to the Customize menu,

Customize User Interface, and then, if you like to create a toolbar for it, in the Toolbars tab,

In the Category: look for "Niklit Scripts", click New to create a new toolbar and drag the script to it.

It's better than the second one because it's based on the Vertex counts, the second script is

Based on the names of the objects, so if you clone an object its duplicate will have an incremental

Name and will not be deleted. Now the first one is not perfect eighter, because some objects might have

The same number of vertices without being duplicates. So it has to be used with caution, and better make a

Copy of the original file first.

Hi!

I just gave the script a try in Max 2018.4 and some warnings:

- first I opened it in Script Editor because ANY Macro is suspect, specially coming from russians!
- selecting the code and "Evaluate all" just bring the first bit of code:

messagebox "If selected 0 Work to all objects\nIf Shift pressed then will select objects by geometry vertex count.\nIf Shift NOT pressed then will select by center objects position" messagebox("Category: \"Niklit Scripts\"")

- I did open it the with "Scripting/Run Script" instead, then "Customize/ Customize User Interface/Toolbars/Niklit Scripts" and drag "Duplicate Geometry Remover" to my Custom Toolbar

- WHITOUT selecting any Objects in my scene, press the icon... and it selects all duplicates. Press delete and works like a charm!!

Hope this helps others!

LAO
