I have investigated using grid systems but it just doesn't seem to be designed for the architectural industry. The company that I work for does a lot of architectural feature work such as stairs, awnings, canopies and lobbies. We need to follow a lot of architectural details and use the grid system setup by the project. We do most of our modeling fairly closely following the Skeleton Sketch Part Method for Large Assemblies. I would really like to see a number of improvements made to the grid systems to better work for our industry. I would like to get some feedback from other people/companies that might be in a similar situation so we can submit one enhancement request that covers most of the ideas. I'll post my thoughts and ideas if there is some interest in this thread.
Feel free to post here if you use grid systems and let us know what you do with them.
