AutoCAD LT is designed for use by students and teachers who need a free, low-cost, quick-turnaround 2D CAD drafting and design program, and may lack the financial or technical resources for a more advanced CAD program. AutoCAD LT runs under Windows 95, Windows NT, or Windows 2000 and the Macintosh OS (system requirements are listed at AutoCAD LT is available as a desktop app or as a web app. AutoCAD LT allows users to edit existing drawings and add new ones.

You can also download AutoCAD and AutoCAD LT mobile apps for Android and iOS devices. AutoCAD LT is a separate CAD program from AutoCAD.

AutoCAD LT only comes with a limited trial version, which does not let users save their drawings. AutoCAD and AutoCAD LT can be purchased as a perpetual version, which allows users to save their drawings, or as a perpetual, no-fee version that lets users save drawings without charges.

Post notes: The resources listed below refer to the free, perpetual, no-fee version of AutoCAD and AutoCAD LT, which is called AutoCAD.

AutoCAD Crack [Win/Mac] 2022

Autodesk’s AutoCAD Free Download program started as a DOS-based version, AUTODRAW, and it originally shipped as a retail product. A later version, AutoCAD R12, added object-oriented programming, which brought the software beyond a simple drafting tool and into the realm of a general-purpose computer aided design (CAD) software package.

The current version is AutoCAD 2014, and it was released in October 2013.

In 2005, Autodesk acquired a version of LDraw, originally developed by the German computer firm, Matra Datavision. This version of LDraw, known as LDraw 2.2, is now included with AutoCAD, and can be used for editing and adding data to drawings. It is the primary source of free GIS (geographic information systems) content and has its own software development kit.

Starting with AutoCAD 2012, AutoCAD is offered in a variety of editions, including AutoCAD LT, AutoCAD LT Premier, and AutoCAD Architect.


AutoCAD has had various editions since its debut in the early 1990s.

Release history

AutoCAD originally came in two main editions: AutoCAD and AutoCAD LT. The latter is a less expensive alternative and is no longer available for purchase.

In the late 1990s, several major updates to the software were released to AutoCAD. These included the major release of AutoCAD 2000. This marked the introduction of the AutoLISP programming language. Also included with AutoCAD 2000 was the introduction of associative arrays, a feature not included in earlier releases. AutoCAD 2002 came with many new features, including the introduction of the architecture line symbol.

AutoCAD 2004 brought the introduction of several new features, including AutoCAD Architecture and AutoCAD Electrical. The next major update, AutoCAD 2005, included the introduction of AutoCAD Structural Drawings, a variation on traditional AutoCAD architecture. AutoCAD 2010 introduced AutoCAD Civil 3D, and AutoCAD 2011 introduced the architectural section symbol, which represents a square-based building that can be rotated and oriented in any direction.

AutoCAD 2014, released in October 2013, introduced several new features, including a revised user interface and a new section symbol. With AutoCAD 2016, the legacy line symbol, which was a little cone-like shape

AutoCAD Crack +

Open the Autocad application and click File -> New.

On the New dialog, select CAD Archivist then click OK.

On the NewArchivist dialog, select Advanced and click OK.

On the Save As dialog, select a location to save the Autocad Archive and click Save.

Next open the Archive and click Open.

In the Archive window, select a CAD file and click Open.

In the Open window, double-click the file you want to use.

In the Open dialog, double-click the file you want to open.

Click Open and the file will be opened in Autocad.

Save the file by clicking File -> Save.

There’s also a CAD/BIM Wiki where you can get more information about Autocad Archivist, including how to get the password.


If you have access to a site called BrowserScape (a ‘free’ search tool), this will find the information you want.
Note: You need to have an ‘active’ Autocad license to install BIM Archivist on your machine.

In my experience, as I’m very new to this software, it does work, but there is a catch. I had to make the Archive folder a different location to the original one (easier to re-install) so I could load the file into Archivist.
(In the file options, there is an area to tell Archivist where to save the file. I chose a different place.)


What is the maximum size of a pinhole camera

Suppose I am taking a picture with a pinhole camera and all the light is blocked except for a small amount that is admitted to the back of the lens. Let the area of the pinhole be $p$.
Now, if $p$ is larger than $p_{max}$ then no photons can get through. So does it mean that the maximum size of the pinhole should be $p_{max}$?


Your reasoning is correct, as a matter of fact for any aperture less than the equivalent diameter of the lens (that is, any aperture smaller than the entire diameter of the lens), there will always be enough light that entering the lens to provide a finite amount of exposure.
But there is

What’s New In?

Working in Draw Objects:

Drawing features are delivered through the feature window, where features automatically persist when the drawing is opened from other applications. (video: 1:14 min.)

All-new Layer and Layers:

Layers and the ability to work with them are now easier to use than ever before.

Layer Manager (video: 3:03 min.)

Layers in a project are now displayed in a detailed overlay, and the ability to filter, sort, and group layers is now far simpler and faster.

Layer Delete (video: 2:43 min.)

To help keep your drawings organized, you can now delete individual layers from their layer group.

Layer Settings and Layers Per Project:

You can now configure how layers and their groups are displayed in your project, and control how many layers you use in a project.

Layer Properties:

Designing and creating layers of the same type (line, circle, arc,…) is now a snap.

Each time you create a shape with the same type as an existing shape in the drawing, it will automatically inherit its properties.

Designing and creating complex shapes (curves, splines,…) is now a snap.

On top of that, shapes that have been duplicated on a layer are now automatically positioned correctly.

Creating project documents with layers:

Projects and project files are a great way to keep your designs and models organized.

Project management is now even easier and faster.


New model: Drafting with the updated 3D Drafting tool.

New 3D View: The new 3D view is a great tool for designing models.


Trace lines and curves more quickly and accurately with the new M-Trace command, and you can even trace shapes that are too small for you to easily select.

New settings, such as the ability to set the thickness of the contour line, make tracing drawings even faster and easier.

Model Display:

Show draft models on the screen:

The Drafting tool automatically recognizes and displays selected models in the drawing, so that you can follow them from drawing to drawing.

You can now see which models are currently selected in a drawing, so that you can select multiple models in the same drawing and trace them.
