AutoCAD, from Autodesk and first released in 1982, is a powerful Computer Aided Design tool. It was, and still is, often considered the standard for CAD tools. Primarily for the IBM PC platform, it was ported to x86 machines with higher video resolutions such as the Zenith Z-100 and NEC APC. Intermittently, versions for the Macintosh appeared. Later versions use a dongle copy protection.

Claris CAD is a computer aided design program developed in 1988 by Claris Corporation in a joint effort with Craig S. Young of Computer Aided Systems for Engineering (CASE). It was based on MacDraw II and Young's earlier CAD application, EZ-Draft. Version 1 was released in 1989 for Macintosh computers running System Software 6 or later. The initial releases were plagued with bugs, especially with the bundled plotter driver.

EZ-Draft provides features that are comparable to those available on expensive mainframe CAD systems, at a fraction of the price. Features like automatic dimensioning with or without tolerance data, multi-layering to provide simplified drawing organization, zooming back and forth between a full size drawing and the smallest detail, powerful geometric construction forms like lines, arcs, fillets, chamfers, ellipses, polygons, boxes, hexheads, slots, and splines, the ability to snap to existing reference positions like endpoints, counterpoints or intersections, the ability to use templates from a pre-defined symbol library, the ability to move, copy repeat, mirror or scale a drawn object, extensive annotation capability including notes, labels and balloons, and support for a variety of plotters. EZ-DRAFT also has features unavailable on other PC based drafting systems like dynamic dimensioning, orthogonal and isometric projections, full compliance to ANSI Standard Y14.5 including geometric tolerances and surface finish an extensive selection of trimming excess constructions off the drawing and a full IGES interface so that drawings created on a mainframe CAD system can be down-loaded into EZ-DRAFT. The user friendly Macintosh interface complete with pull-down menus, mouse and interactive graphics helps the drafter quickly become adept at making high quality drawings - even without prior computer experience.

MacDraft is a powerful but easy to use 2D object oriented drawing environment. Supports auto dimensioning, area calculation, rotation, cursor position indicator, and much more while maintaining an appearance similar to Mac Draw. The product was targeted at users that only occasionally used a CAD program.
