In my map, there are lots of points in layer A. I want to make a line layer B and I want to make start & end points of lines snapping to points in layer A manually.

Can I use points of layer A as a coordinate attribute selection index for my line layer B? Thank you.

    Are you seeking an automated process (i.e. no mouse involved) or you want to draw the lines manually but wish for the points on layer A to be guides to start and end points of the line(s)?

  • Yes I want to draw manually but I want to snap the lines to points A as a guide.

In Settings->Snapping options, you can select layers to which the points of a line can snap to.

You may set the snapping radius to 10 pixel in Settings->Options->Digitizing , to see the mouse snap to the points of the other layer.

After creation of the line, you may move the nodes with the node tool, where snapping is also working.
