[Windows] A request for a simple script of ldcad

[HWQ]

I hope to add a Lua script to detect and delete parts of duplicate coordinate axes
Sometimes I accidentally put in overlapping parts and it’s hard to find them. 
I think this should be easy to implement, such as detecting the same XYZ coordinates in the file and deleting them, but I don't know much about Lua.
hope someone can help me solve it.thk
