I created a worksheet for light and air calculation on one of the design layers and used in view port to show on a sheet.After few days when I opened that particular VectorWorks file. I could not find the worksheet I created. All I can see is that empty viewport on that particular sheet and worksheet no more available on design layer neither in resource browser. I am sure that I saved that file after I created that worksheet because I created the viewport after completing work on worksheet and viewport is there but not worksheet. Can somebody please help me with this?
