There are two options that can be used in BIMcollab WebViewer to create measurements: (1) Laser Measurement and (2) Point to point measurement.
To toggle between these, click the arrow to "Select Measurement type".
(1) 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.
(2) Point to point measurement
This tool lets you measure the distance between two points.
By default, measurements are taken perpendicularly to the surface where the first point is placed. However, this constraint can also be temporarily disabled by holding down the "shift" key.
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. You could also measure the length of a building by placing points on the surfaces of two opposite walls.
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 the Laser and Point to Point measurement tools.
When a measurement is placed and selected, the measurement control bar appears.
