Yes, the extra information was helpful.[quote=“Angel, post:3, topic:44832”]
I don’t know if there is any way for you to embed the Rhino version into the files so we can see without opening them in rhino.
This information is embedded in 3dm files. The ‘trick’ will be to get Windows Explorer to show it to on some reasonable way.
Explorer’s “Type” column only shows type of file - basically a descriptive name for the file extension. So this isn’t going to work.
Windows files can have Properties. To view, right-click on any file and pick Properties > Details. It may be possible to provide some additional data here. If so, you could view by turning on additional columns in Explorer’s Details view.
Another approach would be to provide a Shell Extension (aka plug-in) for Explorer. Rhino already installs a shell extension which lets you view a 3dm file’s thumbnail preview. Perhaps we can just extend this to show you the version of Rhino that wrote the file.
