Change the extent
- One click, no window
- Affects the active view only
- Drag the datum ends per view once switched
Switch every grid and level in the active view to a 2D extent so you can drag the datum ends for this view alone without touching the others.
Grids and levels in Revit share one 3D extent by default — drag a datum end longer in one view and it stretches in every other view referencing that same extent. Customizing just one plan means switching each grid and each level to 2D mode individually, through a tiny round grip that only appears when the cursor sits exactly at the datum end.
A mid-size project with 15 grids and 5-8 levels means 20-23 elements, each needing its own click on the tiny 2D/3D grip, repeated for every plan that needs a custom look.
The mode-switch grip sits right next to the extend handle — miss it by a few pixels and you drag the datum end out of place instead of toggling the mode.
Revit gives no visual flag for which elements are already 2D — edit a grid you assume is isolated but is actually still on 3D, and the change leaks into every other view without warning.
Enlarged details, area plans and sheet-specific views each need their own, shorter datum ends — meaning the same 20-plus click routine repeats for every one of them.
The free ReviTea Grid/Level on the Autodesk App Store can switch 2D/3D too, but only bundled inside a Trim/Extend command that needs a reference boundary picked first, and its last update stopped at Revit 2017 — it won't install on Revit 2022 and later. Datum 2D skips the boundary step entirely, switching every grid and level in the active view in one click:
The interface is matched to the tool window running in Revit.
Create views in bulk (floor plans, sections, elevations) from a level × template × scope-box matrix.
Manage view templates: a full inspector, an A/B compare showing only differences, batch apply with confirmation.
Create sections along grid lines — named to the Vietnamese standard, depth and crop from the model extent.
