There are three options that can be used in the BIMcollab WebViewer to create measurements: (1) Point to point measurement, (2) Laser Measurement, and (3) Coordinate measurement.
To toggle between these, click the arrow to "Select Measurement type".
(1) Point to point measurement
This tool lets you measure the distance between two points.
The point-to-point measurement has a snapping mechanism applied which allows the pointer to snap easily to element corners and surfaces. This enables users to take accurate measurements from either point to point, surface to point, or surface to surface within the WebViewer.
In the example below, the height of the stairs is determined by placing the first point on the bottom tread, then placing the second point on the landing. In the next example, the diagonal measurements are created by snapping between two points.
(2) Laser measurement
This tool lets users place a point within the model, triggering three laser lines to extend towards the X, Y, and Z axes. If the laser line hits an object from both sides, then a dimension appears on the line and the line becomes solid, otherwise the line would stay as a dashed line and no dimensions would appear.
For instance, in the example provided, a vertical section plane was used to view a room's interior. By positioning the laser point at the room's center, dimensions for the Z and X axes were revealed.
This laser pointer tool can also assist in measuring angles. Simply it should be placed on an angled surface, and it reads the degree of the slope.
(3) Coordinate measurement
This tool shows the XYZ coordinates of a point in relation to the model origin (IFC 0,0,0) when placed on any geometry surface. When selecting this tool, a point will be added to your cursor which you can move over the geometry of your model to show a live coordinate.
By clicking on an element with your cursor where coordinates are needed, an annotation containing the XYZ coordinates of that specific point on the element can be created.
This can be used to help determine precise location data in your model.
Controlling Multiple Measurements
You are able to add as many measurements as you need to understand the dimensions of your building, and can use a combination of measurement tools.
When a measurement is placed and selected, the measurement control bar appears.
Some actions you can perform from the control bar include:
You can multi-select measurements by holding down the "CTRL" or "CONTROL" key.
To add more than one measure in one go, you can hold down the "CTRL" or "CONTROL" key when placing Laser or Coordinate measurements.
By default, Laser measurements are taken perpendicularly to the surface where the first point is placed.This constraint can also be temporarily disabled by holding down the "SHIFT" key to make a direct measurement.
You can easily toggle from which point you want the measurement to show from by pressing the "ALT" or 'COMMAND" key (Flip a measurement).
