Problem Description:

Many user has raised the issues about getting,’Value Cannot be null.Parameter name…..’  error during Isometric generation through Openplant Modeler CE. 



And some times Unhandled Exception of JIT(Just in Time)

Reason

        This issue might sometimes is also caused to modification in folder structure or any file missing from default path such that it does not get read.    In Presently scenario whenever using click on Generate Iso he get the error,’Value Cannot be Null’ or either Unhandled exception of JIT (Just in Time ) error directly.

Solution:

          Verify the folder & files are being present in defined path such that it will help to generate the isometric wrt to OOTB environment folder structure.In Below path it can seen that in IFC style cell and config folder is present in OOTB Environment.


           Sometime during modification in Folder structure one more folder is added e.g Isometric styles.In which subfolder with style’s config and cell is defined.



During Isogeneration user view Isometrics Styles icon instead of selecting different styles into that folder

Result:

Restart OpenPlant Modeler CE



And try to Generate the Iso by selecting the proper style:The type of style gets displayed properly directly and upon selection of desired type Isometric can be generated successfully without throwing error.
 
 


Thus resolving the issue during Generation of Iso.
