Hi all
i am trying to use Caesar buried modeler i read help
i model a piping system and after that use buried modeler
when I convert the model the underground pipe generator shows this warning

user defined nodes on the bend curvature will be deleted . CAESAR II space the nodes automatically .

and after that when i come to new piping model input i cant run the analysis because of bend errors
please help me

Do these bends have a large bend radius? You may have to only adjust the error tolerance for teh minimum bend angle. The default is 5 degrees. Go in to the Configuration File (/Tools from the Main Menu) and reset this default minimum bend angle to, say, 1 degree.
Does that help?

It helps
thank you very much
regards
