The World Coordinate System (WCS) is a fixed coordinate system that defines the location of all objects in a drawing. By default, the UCS is coincident with the WCS.   --- **Related References：** - [Commands about 3D Views (GstarCAD 2026)](../../2026/Commands/Command%20Groups/Commands%20about%203D%20Views.md) - [Commands about the UCS (GstarCAD 2026)](../../2026/Commands/Command%20Groups/Commands%20about%20the%20UCS.md) --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences/PLAN.html) · © Gstarsoft Co., Ltd.
