# About Entering 2D Coordinates [GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md) → [Concepts](Help%20System/GSTARCAD/2027/Commands/02%20Concepts/(Concepts).md) **Enter absolute coordinate** Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the *X* and *Y* axes. If you know the precise *X* and *Y* values of the point, you can use absolute coordinates.  **Enter relative coordinate** The last point entered is used as a base for relative coordinates and you can use them, if you know the location of a point in relation to the previous point.  **Enter polar coordinate** When creating objects, you can use absolute or relative polar coordinates (distance and angle) . The distance and the angle separated by an angle bracket (<) when you use polar coordinates to specify a point. Absolute polar coordinates are based on the origin.  Relative coordinates are based on the last point entered. If you know the location of a point in relation to the previous point, you can use relative coordinates.  --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences/About%20Entering%202D%20Coordinates.html) · © Gstarsoft Co., Ltd.
