We manage projects effectively on a global scale, and the software supports very large, massive scale projects by allowing us to see live updates as everyone works from the same database. The intelligent modeling is beneficial because we can extract quantities from our models to pass to subcontractors, helping with purchasing and tracking MTO quantities, and we can compare these quantities with our subcontractors. It's excellent for large-scale projects, particularly for plant designs, modeling, and engineering. **What do you dislike about Octave Forte 3D (Intergraph Smart 3D)?** Some things that could be improved include change management. It would be useful to have a snapshot in time of the first initial revision of a design and then be able to compare new revisions, like rev one or rev two, with revisions stored in the database. Currently, all you can see is the live data, and you can't see previous revisions that were issued. There is also a learning curve; the initial setup can be complicated, though we have good knowledge in-house. Copying setups from one purchase to another could be made easier. It takes some skill, but once you know how to do it, it's quite straightforward. **What problems is Octave Forte 3D (Intergraph Smart 3D) solving and how is that benefiting you?** I use Octave Forte 3D (Intergraph Smart 3D) for plant design, industrial architectural, foundations, piling, and structural to manage global projects.
