Hi Dynamo users,
I have a question about How can I find the areas where lines intersect?
I share sample screenshot .
Thank you for any idea 
Hi @sovitek big thank you, I installed now the Ampersand package and I find this used node and work. No problem for work.
Have a great day !

For those looking for a non-custom node method:
- Build an overall surface for your geometry.
- Group the girds by vertical and horizontal, and extrude vertically by a unit,
- Translate the extruded surfaces down by a half unit
- Convert each group into a polysurface, resulting in two polysurfaces.
- Split the original surface by the first polysurface.
- Then split the set of surfaces by the second polysurface.
- Flatten the resulting list.

yeah a great package, and some of the oldest there still work without any maintance…if you open these nodes many of them is just OOTB nodes…but as Jacob say its possible many ways i think
