In the Revit API, I need to develop a script or application that identifies clash intersection areas and marks them with rectangles. Specifically, I'm looking for guidance on how to programmatically create rectangles to highlight these clash regions within the Revit environment.
The beam is clashing with the column here.
In this scenario, the beam clashes with the column, and I need to visually represent the clash area, possibly using rectangles.
I think you should spend some time on researching optimal workflows and best practices for this kind of task manually through the end user interface before thinking about addressing it programmatically. You have so many options in Revit to affect the view representation of individual elements or areas, and you should make optimal use of those.
For instance, you can change the colour of individual elements in individual views to indicate that two elements clash. You can create individual views that display only clashing elements. There are almost infinite possibilities, and I am sure that others have already invested a lot of time and effort in researching the best presentation methods.
I doubt that simply drawing rectangles around the areas of interest is the optimal way. That said, though, you can certainly draw view-specific rectangles highlighting clashes using detail curves, just like your image suggests.

There are several methods to show the intersection area
1. Get the Intersection Geometry and create a Direct Shape and change its color (To Show the Exact Area as rectangle).
2. Create a Sphere family, get the center point of the intersection and place the family over there (Intersection Point).
I hope this two will help you 🙂
