Caddie is a mid-range computer-assisted draughting (CAD) software package for 2D and 3D design. It is used primarily by architects, but has tools for surveyors and mechanical, civil and construction engineers. It was initially designed as an electronic drawing board, using concepts and tools clearly related to a physical board. [2]
The table does not include software that is still in development (beta software). For all-purpose 3D programs, see Comparison of 3D computer graphics software. CAD refers to a specific type of drawing and modelling software application that is used for creating designs and technical drawings.
CorelDRAW is a vector graphics editor developed and marketed by Alludo (formerly Corel Corporation). It is also the name of the Corel graphics suite, which includes the bitmap-image editor Corel Photo-Paint as well as other graphics-related programs (see below).
Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export. The tables in this article compare general and technical information for a number of vector graphics editors.
The software was first developed by Alias Systems Corporation as StudioPaint, before being acquired by Autodesk and then being spun out into an independent company, Sketchbook, Inc. Originally developed as commercial software, it evolved into a subscription model before eventually being made freeware for personal use.
It is intended to be a feature-based parametric modeler with a modular software architecture, which makes it easy to provide additional functionality without modifying the core system. As with many modern 3D CAD modelers, FreeCAD has a 2D component to facilitate 3D-to-2D drawing conversion.
A man using AutoCAD 2.6 to digitize a drawing of a school building. AutoCAD was derived from a program that began in 1977, and then released in 1979 [5] called Interact CAD, [6] [7] [8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.
AutoSketch 9 running on Windows XP Professional. AutoSketch is a 2D vector drawing program by Autodesk. It is less powerful than Autodesk's AutoCAD and does not support 3D models. AutoSketch uses SKD and SKF, in later versions, as its native format, [citation needed] but can support DWG and DXF. Version 2.1 for Windows supported macros which ...
