AutoCAD Crack Free [April-2022]
AutoCAD is a 2D drafting and design application that uses either a stylus and/or a mouse for drawing, measuring, and working with "shape libraries." Shape libraries are collections of 2D or 3D objects, including path, polyline, spline, ellipse, circle, rectangle, quadrilateral, polygon, and more. Each shape library is associated with a company, manufacturer, or a client. Shape libraries are called "libraries" because they are like groupings of tools.
The standard unit of measurement in AutoCAD is the decimal, and its units of measurement are inches, centimeters, millimeters, and microns. The dimensions of 2D objects (lines, shapes, text, and coordinates) may be expressed in millimeters or microns.
Like most computer software packages, AutoCAD may be used on personal computers, tablet computers, smartphones, and workstations. The minimum specification for a computer to run AutoCAD is a Windows operating system with an Intel-compatible processor and a graphics adapter with 256 MB of RAM (and at least 300 MB of free space) and at least a 32-bit graphics display driver. Many of the features of AutoCAD are not available in mobile apps, and it does not have the capability of drawing, editing, or designing with 3D objects.
The version of AutoCAD used for this report is 2020, with the available specifications listed in the following table.

PostgreSQL: drop a table if the original table's name changes
