Wall Verify

 

Launch the Verify command to perform a model verification. The process is similar to the one performed during Calculate but the software does not design anymore the theoretical reinforcement areas but uses the real reinforcement in place and performs all required verifications. Useful when the wall is not calculated after preliminary sizing, when reinforcement cage is customized after calculation or when reinforcement cage is manually defined from scratch.

 

Errors and Warnings

When applying the Calculate or Verify commands, the Errors and warnings tab in the console displays warning and error messages regarding the design of the wall.
