im trying to place points at a fixed distance from each other, is there a way to place two points at a fixed distance from each other?
One way would be to use the CadTools plugin. There you have a Rectangular Point creator.
The Select Line Segment button (left one) lets you select a line segment of an existing line in a line layer. This line is used as a local coordinate system as the x-axes. You enter how many map units you go in x- and then y-direction for the new point.
Another way is through the Advanced Digitizing panel. In construction mode you can fix the distance for creation of new point in relation to a clicked point in map.
The advanced Digitizing Panel is available when the Advanced digitizing toolbar is on, you layer is editable and the add feature button is activated like below.
