Measuring

Point clouds, Gaussian splats, XGRIDS scans, 3D Tiles, orthomosaics and maps all have measurement tools. They work on the hub and on client share links, on every plan, and they need nothing installed. The 3D model viewer (GLB, OBJ, FBX) and the BIM viewer (IFC) do not have them yet.

Where the tools are

Open a file and look along the bottom of the viewer. A small pill sits there, collapsed to a + button. Expand it and you get Select · Point · Distance · Area · Height, plus a ⋯ menu for units, coordinate system, Simple/Advanced and Clear all.

Tools a file cannot support are shown grayed out with a reason in their tooltip, rather than hidden, so the layout is the same on every viewer.

The four tools

ToolPicksWhat you get
PointOne clickThe coordinates of that point, and its elevation where the file has one
DistanceTwo or more clicksTotal length, point to point or along a path
AreaThree or more clicksThe plan area of the polygon
HeightTwo clicksThe vertical difference between the two points. 3D viewers only

Finishing a shape: double-click, press Enter, or right-click. Point and Height finish on their own. Backspace removes the last point; Escape cancels. On a touch screen a Done button appears in the pill while a tool is active.

The measurement exists as soon as you finish. A card appears above the pill with the value, a unit switch, the badge, an Advanced disclosure, Save measurement and Delete.

Height needs a third dimension, so it is not offered on flat maps. Still photos, video, PDFs and standalone 360° photos have no measurement tools, because a picture on its own carries no scale.

The exception is a 360° photo extracted from an E57. It opens beside its point cloud, and every measuring tool works in the photo: each click is placed on the 3D point the photo shows, so the numbers come from the scan and the measurement shows in the cloud too. See E57 scans with 360° photos.

The badge: what the numbers rest on

Every card carries one of three badges. The badge describes the frame the numbers are in, never the accuracy of the capture. A measurement is only as good as the survey behind it.

BadgeMeaningTypical files
GeoreferencedThe file sits on a named coordinate system, so coordinates and lengths are real-world and can be checked against controlOrthomosaics, 3D Tiles, vector maps, point clouds whose file carries a coordinate system
True scaleLengths are real meters, but the file has no map positionAn XGRIDS scan measured on its mesh (a georeferenced export is Georeferenced instead); a point cloud in a local frame with meters declared
IndicativeThe file carries no verified scale. Treat the number as a rough size, not a dimension. Not for construction, permitting or dimensional verificationGaussian splats; scans measured without a mesh

Click the badge and the viewer explains why that file got it.

Simple and Advanced

Simple shows the headline value. Advanced adds the horizontal and vertical components drawn on the model, the deltas, slope, bearing (where the frame is georeferenced), perimeter and edge lengths. For a Point it lists the coordinates in every system available for that file. Switch from the ⋯ menu or on any card. It defaults to Simple and is remembered on your account.

Units and coordinate systems

  • Your units follow you. Your choice of units, coordinates and readout is saved to your account and applies on every file. Until you choose, you start from your workspace’s default (Settings → Workspace → Units), or from where you are: viewers in the United States get imperial, everyone else metric. Share-link visitors start from the sharing workspace’s default.
  • Metric or imperial, with the unit chosen automatically by magnitude (m, cm, km; ft, in, mi) or fixed. Area follows: m², ha, km²; ft², acres.
  • Feet are international feet. When a file’s coordinate system declares US survey feet, the conversion honors that and the card says so.
  • Point coordinates can be read in WGS84 (decimal or degrees-minutes-seconds) with height, the file’s own grid where it has one (for example MGA zone 54), the UTM zone picked from the longitude, or the file’s local X/Y/Z. Elevations are labeled with their reference (ellipsoid, the file’s vertical datum, or local Z).
  • Click any number to copy it.

The same tools appear on share links for everyone you send the link to. A client’s measurements are for their session only and are never written to the file, so they can measure freely without changing anything in your delivery. Measurements you have saved and marked Shared appear on links that show notes.

Saving measurements

Measurements live for the session unless you save them. Close the file and unsaved ones are gone. The card can be dragged out of the way and stays where you put it; a count badge on the pill lists everything measured so far, and Clear all removes them.

Save measurement on the card keeps it: it goes into the file’s Notes panel with its value and view, and can be named, tagged, added to a list and shared. Saved measurements show in your current units. See Notes.

There is no volume calculation and no cross-section tool. To mark out a 3D region, use a Volume note: trace the outline, then set a height.

Notes by viewer

  • Point clouds: the badge depends on the file. A COPC that carries its coordinate system is Georeferenced; a local-frame file is True scale or Indicative, and the badge says which.
  • XGRIDS LCC and LCC2: measuring needs the scan’s collision mesh, the same mesh Walk mode’s collisions use. With a mesh the badge is True scale, or Georeferenced when the export carries a position on a named grid. Without a mesh, picks land on splat centers and the badge reads Indicative. Mesh chunks stream in by distance; a pick on an unloaded chunk asks you to move closer rather than failing silently. While a tool is active, click-to-walk is suppressed.
  • Gaussian splats: always Indicative. The numbers assume the file is in meters and each pick lands on the nearest splat, not a true surface. Picks need the whole file loaded, so the tools wait until the loading indicator has gone.
  • 3D Tiles: picks land on the tileset and the terrain. Heights are WGS84 ellipsoidal and labeled as such.
  • Orthomosaics and maps: planar math in the file’s own coordinate system, with a UTM fallback.
  • 3D models and BIM (IFC): no measuring tools yet. To measure a building, use the point cloud of the same site.
