I have built my model in caesar & done the analysis. Now i want to generate stress iso in cadworx. I do not have this model in cadworx but want to take the caesar input file & generate stress iso. Is it necessary to build the model again in cadworx. Because to generate the stress iso, in cadworx it is asking for variuos data.

Please advise.

In CADWorx Plant (or Pipe if you have an older version) click the menu item Pipe, then Accessory, then CAESAR II, then System In...

Use the dialog box to select your CAESAR II input (and output!) file and watch CADWorx draw your iso.

For the stress ISO: click the menu item Plant (or Pipe), then Accessory, then CAESAR II, then Stress ISO...

For the output: click the menu item Plant (or Pipe), then Accessory, then CAESAR II, then Annotation...

Try this too: click the menu item Plant (or Pipe), then Tutorial...

My response is simple because the process is simple. Since you have ample software documentaton describing these features my response is directed more to the general readership who may not know of CADWorx Plant.
