## Description

We had the measurements tool implemented in the viewer. [LINK](https://xeokit.github.io/xeokit-sdk/examples/#measurements_distance_createWithMouse)

This is an essential tool for collaboration and coordination in the BIM environment. We should reimplement this functionality and also define the UX for this use case.

Hint from <mention class="mention" data-id="48453" data-type="user" data-text="@Reinhard Wimmer">@Reinhard Wimmer</mention>: see BimVision as a positive example for measurement tools.

Specification as discussed during Monday's call:

  - Measurements button in the toolbar with a drop down
      - length
      - area
      - volume
  - Measurements get listed in a separate tab in the properties inspector pane
      - A button for deleting all measurements
      - A button after each measurement to delete that single measurement
