AutoCAD’s success has been attributed to its ease of use, the simplicity of the user interface, and its cost. It can be purchased at a fairly low price compared to most other CAD software, costing as little as $125 US for the latest editions. It is capable of creating all but the most demanding of architectural drawings with its auto-guidance technology, saving users considerable time and money when designing complex structures. Also, its compatibility with a vast range of peripheral devices and platforms, including Windows, Mac, Linux, the iPad, and Android-based phones and tablets.

Since its inception, AutoCAD has been continually updated and its capabilities have been expanded. In the early years of the 20th century, it was possible to complete a 2D drawing in just a few minutes, but in the 21st century, AutoCAD and its programs have evolved into a full-featured, multi-platform software package. Compared to older and older software, AutoCAD is quite sophisticated.

Another advantage is that AutoCAD is an application that runs on nearly every personal computer in the world.

AutoCAD LT[9] is a less-expensive version of the software that can be used to create 2D drawings.


AutoCAD was developed by a team at 3M’s offices in Minneapolis, MN, known as the AutoCAD Team. The AutoCAD Team was given the task of solving a common problem, the need for quick, efficient drafting. A drawing in this era was a tedious process. An architect would start with a drawing with an accompanying text file, which would be used to generate the design. Once the drawing was completed, any changes would be made and sent back to the architect’s office for approval. The next drawing would be sent back for revisions, with each step potentially taking months to complete. The AutoCAD team was charged with creating a new CAD program that would meet the needs of architects, and ultimately, consumers.

AutoCAD’s rapid productivity was enabled by its ability to automatically generate text based on the lines, arcs and other objects used to make a drawing. The AutoCAD team also included a layout expert to help designers draw a clean, easy to understand design. Another important feature is the team’s continued emphasis on usability and ease of use

3D modeling
AutoCAD includes a full-featured 3D modeler. The interface is similar to Autodesk’s Meshmixer.

AutoCAD’s 3D CAD features are primarily designed for architectural modelling, visualization and documentation. The output format is not the default DWG format, it is Drawing Exchange Format (DXF).

To create a 3D model, users must begin with 2D drawings created in a CAD application. The drawings can be from a Windows bitmap image file, a Microsoft Word document or any text-based program such as Adobe Illustrator. AutoCAD reads in 2D drawings and uses the edges of the drawings to create a 3D model. 3D modelers can take some time to become familiar with their operations. Users who have used AutoCAD’s surface modeling and hatch shading tools may find it easier to quickly generate 3D models. With the release of AutoCAD 2010, AutoCAD’s 3D modeling features were revamped. Now users have a 3D modeling feature-set that offers more control over the modelling process. 3D modeling users can modify and review the 3D model by using a 3D perspective and manipulate and select certain objects using common operations such as moving, rotating, scaling, and deleting. 3D modeling tools are available through the modeling workbench or modeling workspace or through plugins.

A 3D model can be accessed and modified from within any AutoCAD drawing, from a DXF document or from the command line. AutoCAD’s 2D drawing engine can also be used to create additional layers for 3D objects. The 3D modeler offers many standard and advanced 3D modeling features.

AutoCAD supports both top-down and bottom-up modelling techniques. A top-down model consists of a set of multiple 2D layers, which are used to construct 3D objects. Bottom-up modelling is the reverse process. 3D models created using a top-down approach may require some post-modelling cleanup. Many users choose to use bottom-up modelling, because 3D modelling tools provide the ability to rotate the 3D model. Bottom-up models may require more maintenance than top-down models. The 3D modeler allows the user to easily create a 3D model by using a 2D drawing.

Adaptive responses of the thyrotrophin axis to long-term thyroxine treatment in sheep.
The thyroxine (T4) concentration in the circulation decreases rapidly after several weeks of oral T4 treatment, which may have adverse effects on the neuroendocrine control of thyroid function. The aim of this study was to evaluate the acute and long-term effects of long-term T4 treatment on the pituitary-thyroid axis of sheep. Ovariectomized ewes were infused intravenously with either physiological saline (S group, n=4) or T4 at a rate of 1.0 microg/kg body weight per hour (T4 group, n=5) for 24 h. In the second experiment, S and T4 groups were treated for 21 days with physiological saline or T4 at a rate of 1.0 microg/kg body weight per hour. In the third experiment, the pituitary and thyroidal responses to TSH (10 U/kg body weight) were evaluated by measuring TSH, thyroid hormone and TSH receptor mRNA levels at 0, 5, 15, 30, 60, 120 and 240 min after TSH administration. Plasma T4 and triiodothyronine (T3) concentrations were lower in the T4 group after 1 day of treatment, and TSH and TSH receptor mRNA levels were lower at 24 h after infusion. In the second experiment, plasma T4 concentrations decreased to a lesser extent in the T4 group. Plasma TSH increased more rapidly and T3 more rapidly in the T4 group. These data show that a decrease in plasma T4 levels elicits an acute, rapid and transient activation of the pituitary-thyroid axis, possibly as an attempt to maintain T4 concentration within the normal range. In addition, long-term treatment with T4 alters the sensitivity of the thyrotrophs to TSH, suggesting the existence of adaptive mechanisms to limit the deleterious

What’s New In?

You can view, edit and comment on feedback in your drawing. You can save or share feedback to your desktop and keep it up to date. (video: 1:38 min.)

See new Design Notes for each part that you are designing and you can export them for reference at any time.

Creating and editing Dimension styles:

One of the most popular requests from users is to be able to edit dimension styles directly. We’ve made this easier.

In addition to making dimension style changes, we added the ability to set the dimension rule for a dimension style, and we have added support for editing dimensions in the Dimensions dialog. (video: 1:21 min.)

See the Design Notes window for automatic dimension styles and Annotate Geometry with Dimension Comments:

Users love to annotate geometry to support their designs. We’ve improved how you can annotate geometry to the Dimensions window and in design notes.

In the Design Notes window, you can now annotate a list of coordinates. You can also annotate or select a graphic or picture to link to the annotated coordinates. You can export this annotation to a CSV file for further review. (video: 1:50 min.)

Also, we have added support for annotating geometry in design notes and we added an option to create annotation objects from annotation content in the Annotate Geometry dialog. (video: 1:35 min.)

This feature will be even easier to use in the future.

Design Notes:

Users want to link content from their design notes and create lists for searchable content. We’ve expanded the Design Notes interface to make it even easier to link content.

You can link or embed content that exists in AutoCAD such as: text, hyperlinks, graphics, videos, audio files, CAD or spreadsheet tables, and even embedded PostScript (PS) files. (video: 1:48 min.)

You can also link content that exists in your design, including: one or more objects, lists, graphic shapes, block drawings, dimensions, scales, and templates. (video: 1:56 min.)

You can also use the Design Notes window to link to: web pages, PDF documents, images, PostScript files, and annotations. (video: 1:54 min.)

You can embed content from images and you can attach images to a drawing
