Named reference planes (by subcategory) for Constraints(GLOBAL, Walls, Floors, Doors, Windows, Pipes, Etc)

Named reference planes (by subcategory) for Constraints(GLOBAL, Walls, Floors, Doors, Windows, Pipes, Etc)

Allowing orthogonal reference planes as ASSIGNABLE constraints for objects would allow for elements to host to reference planes like levels without  the need for additional LEVELS which interfere with view templates view depths:

1. Corresponding Reference pane subcategory - "Walls:" in thie example, a "GLOBAL" subcategory is visible in all categories to help with filtering.


*or a "GLOBAL" available to all categories

2. Create reference plane:




3. "Global" and "walls" show up under constraint options. This one is an example for "Walls"






Beginning to see the "Level-3-BIM" models with everything in them. To that end:

Currently a datum that has an associated view (on or off a sheet) is what makes a level. Working views throw this off and wreck havoc on templates.


  • The Revit Database needs to be able to explicitly set apart datums from levels. 
  • 'Sub-levels' or levels dependent on a primary would also be useful to establish groupings and movements (We can do this with locked dimensions - however a more structured approach would bring clarity and permanence)
  • View depth control in recognition of levels
    • Include level with view depths as a checkbox so sub-levels and datums cannot interfere with view depths.
    • Worksets  by discipline should be attached to view templates and view ranges in particular for consideration of view depth and visibility. (I know worksets to control visibility is not the greatest idea.)
  • Ability to sort levels by height, not name, or have a columnar organization to sort by name or elevation on selection.

Bentley Open Building offers the ability for Sub-levels. The issue with BOB is that there is only one degree of separation. It might be worthwhile to have 2 or 3  degrees of separation as indicated in example below



Level (D=0)

Kitchen Counter (D=1) Level+900

Lower Cabinet Bottom Level (D=2) KC-800

Lower Cabinet Mid Level (D=3) LCBL+400

Upper cabinet (D=2) KC+900

Upper Cabinet Mid (D=3) UC+400

Upper Cabinet Top (D=4) UCM+400 / (D=3) UC+800 / (D=2) KC+1700


* D=X show degree of separation and specifies the referenced sub level





@kimberly.fuhrman  - I forgot I had already posted this 4 years ago... recently posted another ...


So this one can be merged or deleted : )




@WM_Ron_Allen ,

Thank you! I will merge so you keep the votes!
