is it possible to configure the measurement tool readout in a Geospatial Portal instance?
Although there are some base units in Metric and Imperial that are required, this measurement tool is configurable in the web.config of a Geospatial Portal instance.
By opening the web.config found in (default location) C:\Program Files\Common Files\Hexagon\Services\Instances\yourinstance\ using a text editor program the changes can be made. This is covered in the 'Settings connected with client user interface and it's behaviour' section of that file. Here it will explain what is configurable and what is required.
Please see attached for screen shot of desription section and configurable section.
