Hi Rajesh,
C2Isogen will open the output file and read its data, but it can not sort out the maximum value for any load case. You need to find it out on the output processor, and use the third tab "Nodal Annotation" and type that value under the column "User Annotation", then you can see the maximum loads on isometric drawings.
Regards,
