Point Reactor With Site Massing

New to grasshopper-

I'm trying to use the point reactors to manipulate the buildings on my rhino site. I want them to control the size in the Z direction ( the heights ) . If anyone could help me with the grasshopper definition I would appreciate it.

I know that I need to use the distance/divide/minimum components but I have only practiced this when it was a rec grid. Not sure where and how I input the buildings that have already been defined as masses.

Attached is the DWG of the site. The 3DM was too large to upload; so I'm also attaching a JPEG sample of it.

Thank You!

you need to recreate your masses... i recomend you to extract and use the building curve in plan (i supose that the dwg file contains the curves?), use area component to extract center points, locate your attractor points and check for distance to center points, finally you can use a extrude component in z direction (heights) on the curves, where the height is controlled by the distance/function.
