Creation of geometries by Coordinate system methods using AutoCad
AIM: Create the geometries from P1 to P2 using all the coordinates system methods. You need to use the Line tool to create the geometry.
About:
- There are two coordinate systems in AutoCAD. World Coordinate System (WCS) and User Coordinate System (UCS) define the angle of the XY plane you are working in.
- The WCS should always be used to reference geometry to ensure everything aligns to the center of a file in a real-world location.
- The UCS can be used to orientate the screen to a site. Drawing files will usually have the WCS set by default.
- The current WCS or UCS orientation is indicated by the UCS icon in the bottom left corner of the screen.
- The following questions are done using the coordinate system methods in AutoCAD.
