Totally not.
After seeing the video over and over again, because I was very excited, I'm again dissapointed, and here's why:
In the video, Cris is saying that it's a plug-in object with 3D objects in it and that the only thing the plug-in object does is creating the 2D part of the 3D objects. This means that it isn't like symbols at all, which I though it was at first. This means no worksheet data like symbols, no usage like symbols, no usage in walls like symbols, no extra data, no linking between text and data, no IFC data, ...
This had to be a feature they needed to make part of the symbol object that already exists, not a new plug-in.
Although you could use this plug-in inside a symbol, you can't change the height of the section plane symbol per symbol, so at the end, it only makes our life just a little bit easier because we don't need to draw the 2D part, if we can get good results of course.
This is yet another example of the many many features that are getting introduced into VW half-baked, and never to work on it again untill they find another half-baked feature to replace it. Anyone remember wall recesses? (A functionality that is easier and better done with symbols, except the height changing for the 2D part) If only NVW would throw that and this auto hybrid togheter then put it in the symbol object, then we would have a great feature! And only a symbol object, instead of 3 kind of objects that only does some parts that are meant to be togheter.
Also the use of this will be very very minimal in architecture.
Can you elaborate about why it isnt useful when you make a symbol of it?
