Buffer analysis

[AbhishekSobbana1]

Happy New Year City Engine Folks, 

So, Is there a way to do buffer analysis. Let's say I have split the plot into parts and I want building placed such a way that 10 meter buffer around it there shouldn't be any other building.  

Also, If possible I want to set it for specific like front and back of the building.

I don't want to use setback and offset, since it will use the space in the plot, as you can see I have set the distance building between by using offset rule.

This is quite a difficult task.

One way to achieve such a result without setback is with the CGA minimum distance function this allows for such checks without use of setback and offset. But there is no way in knowing, if it is the distance to the front or backside of the building.
