Splitting a polygon by an overlapping feature

Question

I am using ArcGIS 10.3 with access to advances extensions. There is two features that I have (attached): i) grid (fishnet) of 30 meter:

and ii) Building footprint:

I am interested in splitting/having the building footprint in each grid-cell:

Therefore I have used the Split tool (Splitting a polygon by an overlapping feature). However, the process is always terminated:

I am interested in having building footprint in each grid-cell. Any tips and hints is highly appreciated.

You want to see how much of the foot print is within a given cell, right?  I see in your building footprint attribute table

Area_build  and of course

Shape_Area

When you intersect the building footprints with the cells, the resulting Shape_Area of the new feature class can be used to determine the ratio of how much of the each polygon has been affected by the geoprocessing function.

Let's say your original building footprint data looks like this:

Area_Build = 100

Shape_Area = 500

After the intersection, the the resulting Shape_Area is 250. So you have a reduction of 50% (250/500)  Area_build does not update until you use .5* Area_Build.....

Correct, I would be interested in the amount of building area wich falls into each grid-cell. However I did not get what you mean by:
"If you are interested in your Building area, you should capture the two fields before you intersect with BulidingArea_orig and ShapeArea_Orig.  That way you can proportion what you end up with...."

I appreciate if you explain it in more details...

check if Intersect solves your issue. The output feature class will have the attribute of both the input features.
