AutoCAD history

AutoCAD was first introduced in December 1982. The AutoCAD, DWG, DWF, DWX, DWO, DWI and DWF applications were all developed by the same people at the same time, based on a new graphical user interface (GUI) from the company Graphisoft. These new GUI-based apps were released by Autodesk in 1983. The original price of AutoCAD, which did not include the DWG or DWF applications, was US$1,995. The price for the first Autodesk DWG or DWF products was $1,495, and was reduced to $995 in the late 1990s.

Languages AutoCAD is available in English, Japanese, Chinese, Korean, Arabic, Russian, French, German, Italian, Spanish, Portuguese, and Dutch.

The first version of AutoCAD was a crude draft program that only included two dimensions, with the first version being used in a few companies. By 1987, AutoCAD was already available on mainframes, minicomputers, and microcomputers, and many new features were added, such as toolbars, drafting tables, the ability to draw and edit 2-D and 3-D elements and 2-D, 3-D, and freeform surfaces, 2-D and 3-D dialog boxes, 2-D and 3-D views, the ability to drag and drop objects, and the ability to draw and edit text, symbols, and images. In addition to the graphical objects and elements, AutoCAD also allowed the creation and editing of style-based formats (data interchange format) that were stored in a memory disk, or in the hard drive.

Note: It is also possible to combine data from one file with data from another file in AutoCAD. The method for doing so is known as file linking, and this feature can be used to create complex drawings that contain multiple files.

Graphisoft had started development on AutoCAD in 1980, but it was not until 1983, after Autodesk bought Graphisoft, that it could be developed and released to the public.

For AutoCAD to function, the computer system had to have a

A developmental study of sodium chloride reabsorption in the rat proximal tubule using anti-anionic sites antibody.
The developmental changes in the immunoreactivity of epithelial anionic sites (AS) and the sodium reabsorption from the proximal tubule were studied by immunoperoxidase labelling of peroxidase-antiperoxidase complexes and by the in vivo experiments on Wistar rats aged 1 to 70 days. Immunoreactivity of AS was significantly lower in the early postnatal period and then it increased with the age to reach the adult value at postnatal day 40. The in vivo experiments demonstrated that the Na reabsorption from proximal tubule is significantly lower in the neonate as compared to the adult. The reabsorption and Na secretion in the early postnatal period might be required for the neonate to meet the energy and salt requirements for the maintenance of body fluids and the blood volume.Revision as of 20:37, 15 October 2010


Unconfirmed Story Rumors

There have been several unconfirmed rumors about story arcs that have been developed and need to be officially confirmed in an upcoming storyline. Some of these rumors have already been revealed, and some have yet to be discovered. You can read more about these in the Show/Show Wiki.

These rumors are not set in stone. They are only discussed in the Rumor articles.


If you want to contribute to the game, or have a particular idea for a character, post it here and a developer will either confirm or deny it. If it’s already in the game, you’ll be given credit for it. Also, don’t be afraid to post again if a developer has forgotten about something or something they need to clear up.


“I’ve got a new idea for a story arc. It’s really cool, I think.”

“It’s the best idea I’ve ever had!”

“I know, I know, it’s the same plot as we’ve been running in the current story arc.”

Markup Assistant

Import existing markup to gain access to others or transfer the feedback. Based on your previous drawings, select a part of the drawing or type the text to your own system. The part is selected or typed automatically and the text is inserted in the drawing.

Lookup Table and Radial Chart:

Rapidly create new objects by combining other objects. With the newly developed Lookup Table, create a look-up table based on an existing drawing. Combine and change parts of the look-up table.

2D and 3D Intersection:

Compare two drawings and intersect them. With the new 2D and 3D intersection tool, you can compare two drawings and view the results.

You can also use it to find other 2D and 3D objects and intersect them. The results of the 2D and 3D intersections are displayed in a rich hierarchy view.

Find or filter for objects and text in your drawing. Find an object, create a new shape or select a part of a shape. Use the filter to find parts of your drawings.


Add a fillet or round to your object or text in your drawing. Choose an existing round or fillet or apply a predefined pattern. Apply a set of settings for your round or fillet.

Key frame:

Use time-lapse editing in 2D and 3D drawings. Record and edit changes to a drawing in a drawing session. The recorded changes are integrated into the drawing and are called a key frame.

Drawing overview:

Quickly and easily access the Drawings and Items menu in any drawing session. View the overall settings of the drawing and quickly access the drawing status.

Advanced search with filter:

Searches for drawings that meet your search criteria with the new Filter to find. The search finds drawings that include other objects.

Search in any drawing or directly in the Find tool with the Search in All Objects tool.
