However, there is some debate over the definition of “CAD” software. While it is generally accepted that software that helps with 2D drafting and design, such as AutoCAD, is considered CAD, the term “CAD” can also refer to 2D or 3D rendering software. There are many types of CAD software, including:

2D CAD software

2D CAD software and 3D CAD software

2D and 3D drafting software

2D and 3D printing software


What Are the Types of CAD Software?

2D CAD software

This is the most common type of CAD software, and refers to software that helps you draft, create and edit 2D geometry, such as lines, circles, rectangles, arcs and polylines. 2D CAD software is used for 2D drafting and design. 2D CAD software can be used to create a variety of workspaces that can be projected to any size or scaled to fit the device or output device.

Autodesk AutoCAD is the most common 2D CAD software. Some other 2D CAD software includes:


FreeCAD is an open-source CAD program that is free to use and free to modify. FreeCAD is cross-platform (Windows, Linux, Mac OS X, Solaris, AIX, BSD, and HP-UX), has a modular architecture, and is written in Python.


JigSaw is an open-source 2D CAD program that is available on the Windows, macOS, and Linux platforms.


LibreCAD is a free and open-source 2D CAD software that runs on Windows, macOS, and Linux platforms.


Onshape is a cloud-based 2D CAD service for creating and sharing design work on any devices. Onshape was founded by Autodesk in 2013, and is now a separate company from Autodesk.

3D CAD software

This type of CAD software lets you create 3D models and designs from 2D drawings. 3D CAD software is used for creating and modifying 3D models and 3D designs. Some 3D CAD software programs include:

Because AutoCAD 2010 was developed using Windows Vista, it can be run as a 64-bit operating system on Windows XP.

AutoCAD 2010 is backward compatible with AutoCAD 2008, AutoCAD LT 2007, AutoCAD LT 2009, AutoCAD Classic 2007 and AutoCAD Classic 2009. However, many Windows Control Panel functions, such as the ones to manage the Windows Registry, become incompatible with AutoCAD 2008 (possibly because the version 2007 was not compatible with Vista). A third-party program, like the product Windows Registry Mechanic, resolves this issue.

Due to the new programming language VBA, users are now able to create custom macros. Macros can be executed, for example, if a custom keystroke combination is pressed or when a particular process is finished. AutoLISP is not supported by AutoCAD 2009 or higher.

Since its introduction in 2010, Autodesk replaced AutoCAD LT’s ribbon interface with a new interface based on a tab-like feature. The ribbon can be used to open and close drawing tabs (if the drawing file is saved in tab format). The ribbon also provides a new window mode, Tab-like Display (TLD). TLD replaces AutoCAD LT’s current dual interface model with a single window interface.

Other changes include the consolidation of the “Launch a Drawing” dialog box.

AutoCAD 2010 can run on the Mac OS X operating system.

On the Apple iPad, there are AutoCAD 2008 and 2010 apps available on the Apple App Store.

How to create a variable for an expression including pattern matching and then using it in a function?

I want to create a variable for the expression in order to use it in the function that takes a function as an argument. This is what I did but I get an error saying that variable pattern matches nothing.
func wildcard(_ patt: B, _ f: (A) -> A) -> A {
return f(patt.matcher(A.self))

let a = “abc”
let b = “abcd”
let c = “abcd”

let foo = wildcard(a) { x in x.hasPrefix(“abc”) }
let bar = wildcard(a) { x in x.hasPrefix(“abc”) }
let baz = wildcard(a) { x in x.hasPrefix(“abcd”) }
let moo = wildcard(b) { x in x.hasPrefix(“abc”) }
let nay = wildcard(c) { x in x.hasPrefix(“abc”) }

println(foo) // error: variable ‘foo’ used before being initialized
println(bar) // error: variable ‘bar’ used before being initialized
println(baz) // error: variable ‘baz’ used before being initialized
println(moo) // error: variable’moo’ used before being initialized
println(nay) // error: variable ‘nay’ used before being initialized


You have to use the Pattern (which can be thought of as a static struct that has a method.matcher(String) which is an instance of the more specific type, Match) inside the function definition.
That is, you need to write wildcard(_:patt:f:) instead of wildcard(_:patt:f:)
typealias Pattern = Match

func wildcard
