can anyone help
Welcome to the forum. It may be difficult to diagnose the problem without the model. Can you attach it here? Click on the text "Use advanced editor" at top right of the Reply box and then there will be a link at lower right to attach files.
I had recently installed the solidworks to my computer. I saved the model and closed it once and reopened its fine now.
Thanks. But donot know why it happened.
