❖The Length Dimension tool can be used to draw a length indicator in metres next to objects in your scene, simply click on the tool to make it active, it will then be greyed, then click in your scene and move to the end point, then click again to finish (while drawing you can right click to undo and then replace it):
Your length dimension has been drawn and added in a new layer called Dimensions. This layer can of course be styled like any other in its Layer Properties.
