Previously, the Element Explorer listed model categories but gave you no quick read on how much of each category was actually in the model — you had to open Revit or dig through properties to get a length or area figure.
The Element Explorer panel now pulls real length and area values directly from the model and displays them inline next to each category. Linear categories show a linear-footage (LF) total; area-based categories show a square-footage (SF) total. The numbers update to reflect whatever scope or visibility filters you have active, so you can check quantities on a subset of the model without counting manually.
Isolating a category is now faster too. Double-click any category name in the Element Explorer to isolate it — everything else in the viewer steps back, the isolated category is highlighted, and the view automatically fits to the elements in that category so they fill the screen. Double-click the same category again to exit isolation and return to the full model. The highlighted state makes it visually clear which category is active, so you don't lose your place when switching between categories.
These two changes work together: isolate a category to confirm it looks right spatially, and read its LF or SF total directly from the panel without switching tools or applications. If you want to verify the square footage of all exterior glazing on a floor, for example, you can isolate that category, confirm the geometry visually, and read the area total — all in one step.
