Uses and Available Formats

AutoCAD files are proprietary and typically only natively supported by AutoCAD and other AutoCAD-compatible products. Users have created a number of.dwg or.dxf extensions of the native AutoCAD format for various file types.

Structure

AutoCAD is a vector-based CAD program with similar functionality to other CAD programs such as AutoCAD LT. AutoCAD is based on the graphic rasterizer paradigm. Vector data is used to model and represent geometric shapes, whereas rasterized data is used to represent drawing and text.

Paragraph

A ‘paragraph’ is a section of a drawing containing one or more shapes. A paragraph contains all the geometry that is represented by the shapes in the paragraph. A single shape can also contain multiple paragraphs.

Shapes

A shape is a 2D block of geometry. Each shape is a collection of lines, polygons, arcs, and/or freeform lines and polygons, and may be textured. Shapes can be stacked, which means that one shape can overlap one or more shapes in a different layer.

Layers

A layer is a grouping of shapes, arranged from the bottom up, and can be stacked over one another.

Composite

A composite is a 2D entity that contains all the shapes, layouts, and text that are contained in a drawing.

Layouts

A layout is an arrangement of shapes and layers in a 2D plane.

Layers and layouts are used to organize the drawing into separate areas that are grouped in a logical manner. A user can make selections based on the layers and layouts in the drawing. The shape order in the document and layer names will determine the order that layers and layouts appear in a selection dialog.

Drawing

A drawing is a collection of objects, and a number of drawings can be grouped into a drawing set. A drawing set is a collection of one or more drawings that can be named and organized. A shape can only belong to one drawing. A shape can be in any number of drawings.

Layers

Layer 1

Layer 2

Some use the programming language and systems of AutoLISP, others use VBA (Visual Basic for Applications) or use the higher-level object-oriented.NET framework.

A graphics-oriented scripting language named MathScript was developed for AutoCAD in 2002. It was discontinued in 2006.

Users are also able to create additional applications using Visual LISP.

AutoCAD may be used to create scientific graphics, such as two-dimensional flow visualization and turbulence simulation.

As of AutoCAD 2012, users can also use MSN Live to view AutoCAD models online.

Original program by Yu JiangQ:

Simple, Surjective, Open map. Surjective implies Open?

Let $f : X \to Y$ be a surjective open map. Then, is $f$ necessarily open?

A:

The answer to your question is “no”. To see that this is so, suppose there exists a non-open $f$. Then, $f$ has an open pre-image. Note, however, that the pre-image of an open set need not be open. The easiest example of this is the case of $f: [0,1] \to \mathbb{R}$ given by $f(x) = x^2$. Note that $f^{ -1}(0) = [0,1)$ is not open, but it is an open pre-image of the open interval $(0,1)$.

A:

Surjectivity isn’t enough to ensure openness. Consider $f: [0,1]\to\mathbb R$ given by $f(x) = \sqrt x$. Then $f$ is surjective but not open.
I guess that it might be helpful to take a look at the proof of the inverse mapping theorem.

Q:

Speed up a query for a dataset of a million records

Is there a way I can speed up my SELECT query which is running on a dataset of around a million records?
My SELECT query is taking almost 2 minutes to complete.
I have tried using temp table and Index. The temp table helped in speeding it up by around 5 minutes but this still doesn’t seem good enough.
SELECT
[ID] AS [ID],
[A] AS [A],
[B] AS [B],
[C] AS [C],
[D] AS [D

New draw order control: Start drawings with the new “New” command, so you can easily generate new design data as needed.

Increased precision with the Automatic Grid and Grid Snap

AutoCAD 2023 features a new locking mechanism that will lock the Grid and Grid Snap on any object.

AutoCAD 2023 also includes the ability to directly select points, lines and arcs. This will allow a more precise editing of existing objects. In addition, AutoCAD 2023 introduces new commands for intelligent editing of the Snap System.

Enhanced editing with the new Snap System:

Add and change Dimensions while editing text.

Quickly change the x- and y-axes of a selected Dimension.

Design data from AutoCAD 200 can be easily placed on different coordinate systems.

Add a tabular function to the Dimensions command.

Import and export EESIS files.

Color choice is now included within the Dimension command.

Quickly copy objects and use them as temporary geometry for further editing.

The New command is used in addition to existing commands.

The Ribbon:

The Ribbon is now separated into three sections: Standard, Legacy and Utilities. Each Ribbon section can be displayed and hidden separately.

With the new ribbon interface, you can easily manage and switch between your drawing and toolbars.

Draw tools are now grouped in a separate category. This makes it easier to select them.

Toolbars can be hidden and displayed individually.

A toolbar can also be turned off and set to display only certain commands, for example the Polygon command only.

The Layout and the Layout Manager have been revised to make them more dynamic.

Go to symbol is now available in the View menu.

The new “New View” feature makes it possible to easily define a custom view on the current drawing.

A new dialog window makes it easy to define the custom view properties on a scale of 1:1, 1:100 or 100:1.

New features in the menu commands and ribbon:

Data management: Export and Import of objects
