Issue spheres creation with Revit macro

My current work place uses Dynamo to generate issue spheres to visualize clash location. However, it requires a lot of user’s effort, from installing Dynamo to the system, to opening Dynamo file, etc. In this respect, using Revit API or macro to generate the spheres makes more sense. Below is a macro code written in C# that reads .csv file generated from Navisworks and place sphere family in Revit.

Spheres generated from the macro and color filtered with the attirbutes
