What units does Canvas measure in, and how can I change this?
The Short Answer
The Canvas app will show measurements in imperial units by default, but this can be changed in-app. The default scale for the CAD files (.rvt, .skp, .dwg, or .dae) delivered will be in inches, and this can be changed easily within the CAD program you open the file in.
If you are importing the .obj file of the scan into another 3D program, the default scale is meters. However, different 3D programs have different conventions for how they import .obj files, so you may need to adjust the import settings and/or contact the support team for that particular tool to ensure scale is maintained.
The Long Answer
Canvas will show measurements in imperial (feet and inches) units by default, but the in-app measurements can be easily converted to metric (meters and centimeters). To change the measurements within the Canvas app, just tap on the title in the scan view, and it will show an option to change the units from "Feet" to "Meters" (and vice versa).
Once you toggle your first measurement to metric, it should switch the default measurements in that scan to metric, so every measurement you take after will show up in metric. This default is on a scan-by-scan basis.
If you use our Scan To CAD service, it will be important to note that all of our CAD files are sent with inches scale, but the majority of CAD programs allow you to change units very easily upon import (here is how to do so in SketchUp). An exception to this is AutoCAD, where you need to re-scale the drawing based on your desired unit of measurement.
