I drew lines and a rectangle to make the grooves

I choose the rectangle and turn to connect from geometry < compound objects < connect
then I pick the other lines
I choose the wall and turn it to brobolean from geometry < compound objects < brobolean
then I subtracted the connect objects then I got the wall with grooves
