Options for 'base grid'

Since a couple of versions there is some kind of ‘base grid’ on the Z=0 level. It is useful when starting to model from scratch.

A couple of requests actually:

  • Make it possible to set a level (or plane) for this grid. Similar to a workplane in Revit. Preferably not only horizontal but also vertical, let the user move it around, …
  • Give us the option to hide it. The “Grid” button only shows/hides actual grid lines from the IFC schema, not this base grid.
