setting up Robot so the results would be using standard rebar mat 5m x 2m (150mm spacing) for practicality

Dear Structural Engineers,

I am doing a small project, how do I setup Robot to give me the slab to use standard 5mx2m ø10mm or ø12mm rebar mat that is 150mm O.C. (on center)?

See Attached ROBOT file. 

Any help, direction and or instruction are very appreciated.
