[Komal]

I have used an example code of CAN loopback using nucleo STM32F446RE 
the location is 
C:\Users\.........Your User Name.....\STM32Cube\Repository\STM32Cube_FW_F4_V1.27.1\Projects\STM32446E_EVAL\Examples\CAN\CAN_Loopback

Unable to bulid this project and it is showing Nothing to build for project STM32446E_EVAL.

how can I solve this problem

The better solution here is to switch to STM32CubeIDE which is superior to SW4STM32 in every way.
