When 2D drafting in AutoCAD, you are always drawing in a top-down view in which the X-axis is horizontal, and the Y-axis is vertical. 3D modeling tools are not included in AutoCAD LT.Īll objects and points in every AutoCAD drawing are located at a specific location on the XY grid. However, the Z-axis is utilized in the full version of AutoCAD for 3D modeling. In our tutorials, only 2-dimensional drafting will be addressed, so the Z-axis will not be used. Cartesian is a mathematical term referring to the XYZ axis coordinate grid system. Make sure you have our free AutoCAD class files downloaded prior to beginning the tutorial.Īll drawings in AutoCAD have an absolute XY plane with an origin at 0,0 on a Cartesian XY grid. Learn about the Cartesian XY Grid and its importance in AutoCAD. All drawings in AutoCAD have an absolute XY plane with an origin at 0,0 on a Cartesian XY grid.
