many thanks. unfortunately it didn't solve the problem. It makes nice lines instead, but didn't help to make lines and areas operational for visyalization as polygon does.
i tend o think there is some problem with shapefile, but I have tried multiple times to export...
Could there be a problem with that there is to many points in a while to process?
Could you please share your workbook with us.If the Data is confidential then atleast share the picture which depicts the no of marks which is available at the Left Bottom of the page.
You can also check in another way like Zoom (Right Click-> show zoom Controls) the Area and see whether the marks are appearing appropriately or not.Please let me know if it works or not
