Revit 2021 Managing Structural Groups using Selection Sets


Some BIM Execution plans call for the Structural model to be split into the same levels and zones as the Architectural models. When it is required that the structural model must also be also for structural analysis using Autodesk Robot or some similar product, then the Structural model is composed of only one model or is divided at structural disconnects.

Structural models can therefore be large and, unless one has a great computer, can place a significant overhead on one’s hardware resources. There are various tricks one can use to mitigate this.

  • Crop plan views
  • Work in section boxes in 3D
  • Use groups

I name groups like I would a normal Revit file, and I include their names in the file database. This is because they can be written out as files on their own that can be linked in if the structural analytical model is not required and a linked model strategy is followed instead.

It is not possible to create a visibility graphics filter for groups, so instead a selection set is used to group groups instances together. The selection set is named after the group name.

Now it is possible to manage the graphics of the groups using the selection set by overriding the graphics in the view (not visibility graphics overrides)

Also create a vertical section box around the zone of interest, as this limits the graphics the computer must process.
