Within QGIS, I have a 'cable' layer and within such layer I have the columns 'from' and 'to'. The use of this 'cable' layer demonstrates a real-life cable travelling from one piece of equipment to another.
Say I had a layer called 'equipment' with two point features I want a cable to connect to. These two points are labelled 'Point A' and 'Point B', is there a way to auto-populate two columns in the 'cable' layer to show that the line drawn is starting from 'Point A' and ending at 'Point B'?
