Hi Mahmound, 

If you just intend to change the geometry, you can use the use edit tool to create a new line across the polygon. 

Constructing polygons from the shapes of other features—ArcMap | Documentation (arcgis.com)

Is this what you were after?

firstly thanks for your replaying 

the tool that you notified it is not work for what i want and make gaps and clip each build according to the red polygon like that 

i want tool split by percentages each red polygon split to polygon and on the build's edge and without gaps

like that
