Though AutoCAD has been the most popular computer-aided drafting (CAD) software package in the world for over 35 years, its current support is for Windows XP and Windows 7 and there is no support for Microsoft Windows 8 or Mac OS X. As such, AutoCAD is considered legacy software.
The name Autodesk AutoCAD comes from a phrase in Walt Disney’s movie “Snow White and the Seven Dwarfs”:
I am one of those Autopia overbooking peons.
AutoCAD was created in the late 1970s by a team at the company formerly known as Charles E. “Chuck” Arnold & Associates, also known as Arnold Engineering Development Co., in San Rafael, California. It was developed and first released in December 1982, and was originally available only for the Apple II, Atari, and IBM PC compatibles.
In March 1992, AutoCAD was released for Macintosh. In 1993, AutoCAD was ported to the Amiga, following the purchase of the company by Autodesk.
Autodesk later purchased the CADDLab company and merged it with Arnold Engineering Development Co., renaming it to Autodesk CADD.
In 1990, the first 64-bit version of AutoCAD was released.
Acquisition by Autodesk
On August 1, 2009, Autodesk announced the acquisition of a business unit, including Autodesk Autocad software, from The Blackstone Group LP for $2.9 billion. In 2010, Autodesk acquired SketchUp SketchUp, Inc. for $2.3 billion.
On February 18, 2013, Autodesk announced the acquisition of parametric design software applications from Synnex Inc. The name of the product, SynDIG, has been changed to AutoCAD.
Originally, each version of AutoCAD was required to be registered with the U.S. government. The software also originally used the controversial CVSS (Common Vulnerability Scoring System) methodology.
Before 2010, the price of AutoCAD was US$1299.00. However, in 2010, a new product line, AutoCAD 360, was released for a price of US$899.00. In 2011, Autodesk announced a subscription plan for AutoCAD, AutoCAD LT,
Support for File Formats
AutoCAD supports the following drawing file formats:
AutoCAD DWG (originally developed for AutoCAD 2D)
AutoCAD DWG/DXF (originally developed for AutoCAD 3D)
AutoCAD native files
AutoCAD native PostScript/PDF (originally developed for AutoCAD 3D)
AutoCAD native HPGL (originally developed for AutoCAD 3D)
AutoCAD native VTK (originally developed for AutoCAD 3D)
XPL (originally developed for AutoCAD 2D)
AutoCAD for Android app
In August 2012, Autodesk announced its AutoCAD app for Android. The app is available for free in the Android Market. Autodesk and Android work together to bring the AutoCAD app to Android devices.
AutoCAD for Android provides some of the same features as AutoCAD, including collaboration, sharing, and presentation.
AutoCAD LT is available for Android.
AutoCAD 365 (formerly AutoCAD Architecture) app
In 2014, Autodesk announced AutoCAD 365 Architecture app for Android, which includes advanced architectural drafting capabilities. The app features BIM (Building Information Modeling) data, including 2D, 3D, and VR/AR.
In 2018, Autodesk released Autodesk Cloud, which is the next generation cloud offering from Autodesk. Autodesk Cloud provides the following services to Autodesk customers:
Cloud Library: A cloud storage repository where CAD files can be saved and shared
Cloud Catalog: A web-based repository to manage CAD files
Cloud App Center: An application store for developers to add new functionality to Autodesk cloud services

Replace string in a list with strings in another list
If I have two lists. I want to loop through each list and replace the string in the first list with the string in the second list. So for example if I have:
B = [‘Java’, ‘Python’, ‘Php’]
I want to create a function that replaces the string in A with the string in B so the result is:
I’m pretty new to python and this has been a bit of a tough road. Here’s my failed attempt at doing it:
def replace(A, B):
for i in range(len(A)):
for i in range(len(B)):
if A[i] == B[i]:
A[i] = B[i]
B = [‘Java’, ‘Python’, ‘Php’]
C = 
def replace(A, B):
for x in A:
if x in B:
You could also use a list comprehension, like so:
def replace(A, B):
return [x for x in A if x in B]
