Is there an Equiv to AI Divide Tool? If not...

If not - what is the best way to replicate that tool?

I attempted myself but I cannot tell what it's doing exactly to replicate it in VBA.  It sort of looks like its trimming & intersecting but not really. It's kind of hard to decipher. In any event I need a tool similar... Is there a post for this by chance or anyone who can help? 

IF there isnt. Is there a post or someone who can help with a node function similar to inkscapes / extension/ add node function? It like evens out all the nodes along a curve with a value (and doesnt alter the shape). If not that's cool. The divide one im looking for as of now. 

Any help would be appreciated.
