Coordinate plotting grids for non-planar surfaces. Plotting locations in a 3D space is based on an XYZ coordinate system - while 2D Space is based on an XY system. Since surfaces are not necessarily planar - the UVW coordinate system is used to plot

Revit is often used for designing buildings and creating 3D models of architectural designs. It allows architects to create detailed building designs, visualize the project in 3D, and produce detailed documentation and construction drawings.
Revit is a contraction of Revise-Instantly.
