I would suggest to add Grid system at column bases and also create floor levels.
This would help us to isolate the grid views & floor levels during the time of geometric modelling.
Grid Manager (As available in Steel AutoDrafter Workflow)
This Feature is found very Good for all the 3 Axes Views.
I am glad to hear that you found this very good. My question though is for what purpose? Your idea is to have a gird that has what characteristics and what benefits should it offer? There is already a couple of grid tools (one in the Analytical Workflow and another in the Physical Workflow) that can be used to define parts of a model. What are you specifically looking for that these tools do not provide?
