For some reason an outsource ally in the business uses '18 & the current project on site is still '17. Simply save saveas 2017 version is IDEAL.
Sorry...I didn't see the content you typed into the quote.
Um...you obviously don't understand the question I asked. I did not tell you the difference between 2d and 3d.
This is way oversimplified, but boiled down to the very basics, Autocad is a very fancy set of tools for making lines between points. Those points can have Z values, and thus Autocad is 3d capable. But still, the data it keeps in it's file format, again way oversimplified, is a list of points that have lines between them. You can put out a new version, adding all sorts of new tools for drawing lines between points, and still the file format can remain the same, because it doesn't care about which tool you used to draw the lines between points, it only cares about keeping track of the points.
Revit is a completely different animal.
I asked you a question. I'm trying to help you understand something. I'll ask it again.
If Revit adds a new feature...let's say something like vertical wall reveals...how can you possibly expect a model containing such a feature to work in an older version of Revit that did not have vertical wall reveals? Where would the parameters for the new feature be stored in the older database format?
