Why is the latest version in True View 2013? I have to do a volume surface for a client. I received a drawing from the primary engineer that was created in 2018, so I could not open it in my 2017. I asked her to save it down and resend which she did, to 2013. I didn't know why until I had IT download TrueViewer, and see that that is the latest option. Now when I try to use their contours to create a surface it tells me I can't because the objects were created in a newer version......

Please tell me there is a way to do this. I tried copying the ex and prop contours to a new drawing...nope. Thank you for any help you can give
