Prior to AutoCAD, topographic maps were created using paper drafting and other manual methods. To design and draw topographic maps, a user was required to be familiar with map projection techniques, and have basic understanding of GIS (geographic information systems) concepts such as coordinates, datums, and linear scales. With the introduction of AutoCAD, topographic maps were drawn on screen by virtually placing the user’s mouse over a map scale at any given location, and selecting a point of interest on the map with the computer mouse. The point of interest was subsequently inserted and scaled in relation to the map scale. This feature was revolutionary and enabled users to lay out topographic maps at any scale, or orientation, without the need for a map projection table, map projection software, or any knowledge of map projection.

The AutoCAD application allows a user to draw topographic maps in a very simple manner. The user first maps the area of interest on a large scale map and selects the points of interest in that region, after which the points can be located on smaller scales. For each point selected, the coordinates, elevation, and the scale at which it was drawn are recorded.

A large-scale topographic map, built using the drawing tools in the AutoCAD application, can be printed in color, black and white, or converted into black and white outlines. On small scales, outlines of the topographic features are printed as one-point contour lines with a thickness of 10, 20, 30, and 50 feet (3, 9, 13, 20 meters). The contours are printed as black lines for each chosen thickness, and color is added by using AutoCAD’s color fill and hatch patterns to color the areas outside of the contour lines.

General Data

Key Characteristics

AutoCAD is a commercial 2D CAD program produced and marketed by Autodesk. The application was first released in December 1982, and its first public demonstration was held in September 1983 at the Joint Computer Conference in Atlanta, Georgia. Autodesk released AutoCAD for the first time as a shareware application, with a pay-to-use license for all versions, in 1985.

The original AutoCAD was a desktop application that ran on a microcomputer with an internal graphics controller and could only display the maps within a one-hour time frame. The user could manually enter data into the form, while the computer processes the data and creates a topographic map

A review of the literature on the role of iron in genetic hemochromatosis, the pathophysiology of this disease, and the diagnosis and management of hemochromatosis is presented. Diagnosis of hemochromatosis is based on a high index of suspicion, as patients with iron overload will often be asymptomatic and are at increased risk for morbidity and mortality from the sequelae of iron overload. Although some patients with hemochromatosis develop progressive, symptomatic iron overload, others do not. The HFE gene is responsible for hereditary hemochromatosis in most populations, and HFE mutations are probably responsible for 90% of hereditary hemochromatosis. Non-genetic forms of hemochromatosis also have been identified. The HFE gene is an important determinant of iron absorption and stores. C282Y and H63D mutations in the HFE gene are the most common forms of hereditary hemochromatosis, and most patients with hemochromatosis have at least one of these mutations. The most common non-genetic form of hemochromatosis is idiopathic iron deficiency anemia. Anemia of chronic disease, pregnancy-related anemia, and thalassemia intermedia, including erythrocyte α-thalassemia, are other known causes of iron deficiency anemia. Hemochromatosis is a frequent cause of hepatocellular iron overload. There are no uniformly accepted guidelines for the diagnosis and management of hemochromatosis. Decisions regarding the diagnosis and management of iron overload and hemochromatosis are best made on an individual patient basis.This invention relates generally to non-volatile memories and particularly to electrically erasable and programmable read only memories (EEPR

## Share Autodesk products

Autodesk Share was developed to provide users an easy way to share their CAD drawings and to collaborate with others in their work. In Autodesk Share users can:

Share work drawings with others on their network

Open and edit shared drawings

Save shared drawings for others to open and edit

Create groups

Create and edit content (text, drawings, etc)

**Be aware that once you share a CAD file, it’s very difficult to delete the shared files. Autodesk will not delete any shared files.**

Autodesk Share is part of the Autodesk subscription service and the initial version of the application became available in early 2011.
