Based on QCAD 3
In addition, you can make good use of the ' Set Relative Zero' option from the Snap tool-set.
For example if we set our new relative zero point at an intersection, we can now draw new
entities (lines, circles etc.) with starting points 'relative' from this new 0,0 'relative' coordinate.
In this example I am drawing a circle with a radius of 10. After choosing the circle option (Center, Radius cr), I am presented with snap options.
The snap option I am using is 'Coordinate' (sx).
This snap option presents X and Y coordinate input fields (in the top tool-bar) for either 'absolute' or 'relative' coordinates, in this case my starting point (center of circle) is relative to the last position I set (Relative Zero).
* Note -you must 'Tick' the relative field input box!
* Once you have specified your first point for example with a line - click on the green tick to set this point.
To exit this snap option (coordinate sx) you can either click on the Restrictions Off (+) snap button or on the Auto (SA) snap button.
