1. Hey, I am not spreading any rumours first. Also, it's a Adsk forum not Cadworx forum to make ppl to get fear. I clearly mentioned that it's a rumour.
2. I am the happiest person if rumour is true. Because not good interoperability is there with Intergraph products.
3. If you see the latest version of CAESAR ii, Intergraph have removed the dwg interface.
4. No possibility to bring smart plant vue in Navisworks. one can see dgn, Rvm files in Navisworks, why not smart plant?
5. Adsk Plant 3d is not dependent on other software, they have their own ISO engine, it's not as equal to Isogen, but ok, one can manage. Hope it will be equivalent to Isogen soon.
6. If you take Intergraph Cadworx, they directly dependent on Adsk Autocad. When they are dependent to them why shouldn't they extend their interoperability.
