# Use Precision Tools [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [User Guide](Help%20System/GSTARCAD/2022/User%20Guide/(User%20Guide).md) → [Create and Modify Objects](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/(Create%20and%20Modify%20Objects).md) With the help of a variety of precision drawing tools, you can produce accurate drawings quickly without tedious calculations. [Coordinates and Coordinate Systems](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Coordinate%20and%20Coordinate%20System.md) To establish workplanes and for convenient coordinate entry, you can use a movable coordinate system and the user coordinate system (UCS). [Object Snap](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Object%20Snap.md) You can specify points relative to existing objects such as endpoints of lines or center points of circles, Instead of entering coordinates. [Polar](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Polar.md) If you use polar tracking, the cursor will move according to the specified angle. [Ortho Mode](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Ortho%20Mode.md) After opening the ORTHO mode, you can restrict the cursor to move horizontally or vertically. [Grid and Snap Space](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Grid%20and%20Snap%20Space.md) To enhance drawing speed and efficency, you can display and snap rectangular grids. [Get Geometric Information](Help%20System/GSTARCAD/2022/User%20Guide/Create%20and%20Modify%20Objects/Use%20Precision%20Tools/Get%20Geometric%20Information.md) To get information about the objects in your drawing and to do useful calculations, you can use the inquiry and calculation commands.
