Navigating and interrogating a 3D BIM model used to mean relying on the viewer's default controls, with no quick way to measure distances, cut a section through the building, or walk through the space.
A floating toolbar now appears at the bottom center of the BIM viewer whenever you have a model open. It gives you four tools in one place, each accessible with a single click. Only one tool is active at a time: turning one on turns the previous one off.
ISO / 3D toggle switches the camera between isometric and perspective projection. The button reads ISO in the flat, distortion-free view that's best for comparing distances across the model, and 3D once you switch to a natural, true-to-life perspective.
Walk mode puts you into first-person navigation, with an on-screen guide the first time you turn it on. Move with WASD or the arrow keys, go up or down a floor with Q and E, hold Shift while moving to run, drag with the left mouse button to look around, and double-click anywhere to teleport there instantly. Use it to walk a space floor by floor before a site visit or review clearances room by room.
Measure tool lets you click two points anywhere on the model to see the distance between them, broken out along the X, Y, and Z axes. Toggle between feet and meters with the FT / M switch in the toolbar, and use Clear to reset and start a new measurement. Only one measurement is active at a time.
Section tool lets you drag a cutting plane through the model to expose interior geometry. It's the fastest way to look inside a wall assembly, check floor-to-floor heights, or review MEP routing without the surrounding structure in the way.
Alongside the toolbar, two other improvements arrive with this release. The Element Explorer now includes a Site scope, covering site elements such as topography, planting, and parking. Site elements render in a neutral off-white to distinguish them visually from the modeled building. Look for the Tree icon in the scope selector to find it.
Level data in the Levels popover is also more reliable. The viewer now reads level information from a broader set of model properties, including "Reference Level" and "Base Constraint," so the popover reflects actual building levels rather than returning an incomplete list for models where level data was stored under a non-standard property name.
