AutoCAD, originally called Auto-Draft, started as an add-on module for the program Auto-Graph, which was developed by a company named Graphix. Auto-Graph is a program to create 2D graphs. However, in the early 1980s, it was difficult to run 2D graph programs on computer systems with less than 64 MB of RAM.
Autodesk acquired Auto-Graph, and Autodesk re-released Auto-Graph as AutoCAD. This new version was designed for the modern PC. AutoCAD was initially released in 1984 as a program for the Apple II.
AutoCAD was later released for the Mac in 1985. It was included in Auto-CAD and 2D Computer Graphics, a package that also included Auto-Align. Auto-Align is a program for editing and viewing 2D, 3D, and perspective drawings.
In 1987, the development of AutoCAD was taken over by the new AutoCAD Company. The new AutoCAD Company is a joint venture between Autodesk and the Japanese company Toshiba, which has an interest in the computer and electronics industry.
The latest version of AutoCAD is AutoCAD LT, which runs on Mac and Windows. AutoCAD LT was first released in 2004. The latest version is AutoCAD LT 2016, which is a major upgrade of AutoCAD LT 2015. The latest version of AutoCAD is AutoCAD R2014, which runs on Mac and Windows. The latest version of AutoCAD R2014 is AutoCAD R2016, which was released in 2016.
Other software applications that may be used with AutoCAD include:
– AutoCAD Tracker, which allows AutoCAD to track and update files that have been saved in external formats such as the STL, IGES, and STEP formats, and transferred to AutoCAD.
– HomeCAD, a free Windows desktop CAD software application. It is an alternative to Autodesk® AutoCAD® software. It is compatible with AutoCAD files, and can be used to create, edit, and manipulate drawing files.
– Trimble® Discovery, which allows users to browse CAD models online, design and perform engineering tasks on the cloud, and synchronize and share data among mobile devices.
– Windows® Mobile, which is a platform for apps that are available for Windows mobile devices such as
AutoCAD 20.1 Free [Mac/Win]
The software has several other modes of operation, including:
Graphical User Interface, or GUI, mode (v10 and above)
AutoCAD Civil 3D
AutoCAD PLM (Product Lifecycle Management)
Active Window Manager
AutoCAD is available for several platforms, including Microsoft Windows, macOS, Android, iOS and Linux. AutoCAD is available for both 32-bit and 64-bit Windows systems. For 64-bit support, AutoCAD is not the only CAD software, but it is the most popular CAD software on Windows.
The Windows version of AutoCAD is available in three major versions: X, XI and R13. X is the free version, XI is the paid version, which comes with the applications Standard, Architectural Desktop, Civil 3D, Mechanical Desktop and AutoCAD LT, and the R13 version, which is offered only as part of the AutoCAD R13 Maintenance subscription.
Supported operating systems
AutoCAD is primarily supported on the following platforms:
Microsoft Windows – Professional, Enterprise, and Ultimate
macOS – 10.6 and above
Android – Android OS 2.3.3 or above
iOS – 4.3 or above
Linux – Ubuntu 16.04 or above
Autodesk offers free and paid technical support services for users of their products. At a minimum, Autodesk will supply the web link to the support site for the product that you are using. At the time of this writing, Autodesk will provide support for AutoCAD on the Microsoft Windows platform for free, while support for other platforms is a paid service.
The paid support service is designed for professionals and business users. The support contract, which can be purchased at Autodesk’s website, is non-transferable and is valid for the purchase period.
Additional support for AutoCAD Architecture is provided by Autodesk’s Professional Services team. Unlike standard support, Architecture Support is designed for architects and consultants and requires some level of programming knowledge.
AutoCAD is available on Microsoft Windows operating systems.

how to create a custom UIButton that looks like a watch
I want to create a UIButton that looks like a watch, does not respond to touch, and has a colored band.
I can’t seem to figure out how to do it, it looks like I can only define a background image for a standard UIButton and use tint color on the existing image.
I want to know how I could achieve this effect, can someone point me in the right direction?
You can use a gradient button. The only trick here is to set the same mask for the button’s background as the gradient would, but set a tintColor of the same gradient that will be used as the background.
Check out UIButton’s -maskToBounds property and -tintColor properties for further info.
For example, here’s a gradient button with a green background and a black shadow.
// create the gradient
UIGradientLayer *gradient = [UIGradientLayer layer];
gradient.colors = [NSArray arrayWithObjects:
gradient.startPoint = CGPointMake(0.0f, 0.5f);
gradient.endPoint = CGPointMake(1.0f, 0.5f);
gradient.frame = CGRectMake(10.0f, 7.0f, 320.0f, 50.0f);
gradient.cornerRadius = 2.0f;
gradient.masksToBounds = YES;
gradient.backgroundColor = [UIColor colorWithWhite:0.0f alpha:0.5f].CGColor;

Added new commands to the 3D Command Manger:
Create, Cut and Copy: Select an object or a group of objects and create a cut and move, duplicate and rotate the objects, or change the properties of one or more objects.
Send as Batch: Send a series of drawings, cut, duplicate, or rotate them, and give them a name. You can also convert them to an annotative link, export the elements to a PDF or Word document, and more.
Create Connections: You can create dynamic links between objects. Any object can be the source of a connection, while the destination can be a section, block, layer, text, or a group of objects.
Move Target: You can copy objects to another location and apply an annotation or a dynamic link.
Layout: Draw new layouts to fit the new block positions.
Define and apply alternate grips. You can create a new object by drawing with a different grip.
Duplicate existing objects.
Delete objects and groups.
Zoom to an object.
Zoom to a viewport.
Convert to PDF, Word, PowerPoint, or Image.
Export objects as files or as PDFs.
Export to PowerPoint.
Export to Word.
Save a drawing as a PDF, including annotations, and add a short description.
Set/unset the color of text and annotative objects.
Set/unset the color of the non-printing background (default in PDF export).
