In AUTOCAD, Relative coordinates are based on the previous point entered. To specify relative coordinates, precede the coordinate values with an @ sign . with the help of @ sign the preceding point becomes the origin for the next point.
@@TECHCAD Thank you for your time to reply. Unfortunately it is not the same thing. I try to start a line at a distance relative to a known point to another point (relative or relative to another point, or in absolute coordinate). The relative to another point is managed by "From" in the context menu. I learned that "From" has some bugs. It might not work if the "Command Line" is not docked. I will try it later today.
Dear In Relative coordinates no angle will be taken, Actually u are asking about Polar coordinates. Kindly watch this video, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K8a1KJ2L51A.html
