Hey Paul,

Use 'snap on Endpoint' for this.
Using the specific snap options is the way to go in all CAD work.In most CAD programs there is an 'auto' snap command which will snap to the nearest exact precise snap point - which normally is end, middle, centre etc. Hopefully at some point there will also be this option in LibreCAD, but for now just make sure you have the correct snap option selected.
