As of version 2016, AutoCAD is the fourth-most-popular application on the Mac App Store.
The first product that has been called AutoCAD was released by Draft-Eze Systems in 1981. Autodesk acquired Draft-Eze in 1994. When AutoCAD was released, the version number for the product was always greater than 10, whereas other products would usually be released with a version number of 10. AutoCAD has been modified in many ways since its first release. In 1985 Autodesk released AutoCAD 1.0, which was a 16-bit program that required a 286-based computer to run. Later it was released on the MS-DOS operating system in a version called AutoCAD 2.5.
AutoCAD and AutoCAD LT, two types of AutoCAD, have been available since the earliest versions of AutoCAD.
AutoCAD is a high-end drafting application used for architectural, mechanical, and civil engineering projects. It supports both the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) CAD standards for drafting. AutoCAD is widely used in the transportation industry. In 1999, 74 percent of the transportation-related project value in the United States was in the transportation civil engineering industry, and the use of AutoCAD increased by 18 percent during the five-year period of 1998–2002. Autodesk has ported AutoCAD to operating systems other than Windows.
Types of geometry
AutoCAD can recognize any type of geometry that a user can imagine and create. There are three types of geometry:
Geometric primitives, such as lines, arcs, circles, splines, and spline segments.
Geometric solids, such as boxes, cones, cylinders, pyramids, and spheres.
Dimensions, such as linear or angular dimensions, as well as projective or geographic dimensions.
Each geometric primitive is user-definable. Some users prefer a more rigidly defined geometric primitive, while others may require a greater degree of flexibility. The following table illustrates how a user can vary the behavior of a line.
AutoCAD supports the following CAD functionality:
AutoCAD can perform the following tasks:

Efficacy and safety of dabigatran etexilate versus warfarin in patients with atrial fibrillation.
Trial data suggest that the direct thrombin inhibitor dabigatran etexilate (DE) is as effective as warfarin in the prevention of stroke or systemic embolism in patients with nonvalvular atrial fibrillation (AF) at relatively low doses. However, the study populations in the RE-LY and ROCKET-AF trials had substantial differences in baseline characteristics. Consequently, the benefit of DE over warfarin at the clinically relevant dose (150 mg twice daily) has not been established. We assessed the safety and efficacy of DE compared with warfarin in a randomized, double-blind, phase 3 trial that enrolled 2393 patients with AF and a prior history of stroke or transient ischemic attack (TIA) to determine the relative efficacy of DE at a dosage of 150 mg twice daily (DE150 group) compared with warfarin at a dose adjusted to maintain an international normalized ratio of 2.0 to 3.0 (warfarin group) and the safety of DE at a dosage of 110 mg twice daily compared with warfarin. The primary efficacy end point was the composite of stroke or systemic embolism. The primary safety end point was major bleeding. For the primary efficacy end point, a hierarchical testing procedure was used to examine dose-dependence and to determine whether the relative efficacy of DE150 compared with warfarin was noninferior to that of DE110 compared with warfarin. For the primary safety end point, a generalized estimation equation approach was used to test for superiority. The overall primary efficacy end point occurred in 37 patients (1.6%) assigned to DE150 and in 36 (1.5%) assigned to warfarin (hazard ratio, 1.05; 95% confidence interval [CI], 0.72 to 1.54; P=0.
