AutoCAD is best-known for its ability to create 2D and 3D drawings. Initially, the basic functionality was only available to engineers. In the early 1990s, the need to sell AutoCAD on a broader scale for the architectural and architectural-engineering markets caused the team to re-work the application. The initial architecture was based on the top-down approach, with different tools (2D drawing tools, 3D tools, etc.) being integrated into the application, with each new tool’s interface based on the idea of the previous tool’s interface. The development and marketing of AutoCAD was headed by John Walker (chief architect and original Autodesk employee) and John Simpson (senior product manager).

In 1998, John Walker left the Autodesk management team and John Simpson became the Chief Architect. For the first time, AutoCAD started selling for a home user market. The 2D architecture was revised and re-released as AutoCAD 200. Since 1998, AutoCAD has been integrated with other Autodesk applications, including AutoCAD LT and AutoCAD Architecture.

In 2009, AutoCAD 2010 was released. AutoCAD 2007 was also re-released as AutoCAD LT 2008. This version was mainly focused on simplifying the user interface. AutoCAD 2012 was released on December 22, 2012, with a new user interface and the introduction of many new features.

In 2010, AutoCAD 2013 was released. This version introduced many new tools and architectural features, and many capabilities that were previously only available on AutoCAD LT.

Compound objects, such as compound curves, have their own APIs for manipulating their properties.

Net framework
AutoCAD can interface with third-party Visual Studio projects and Visual Studio libraries by creating.NET assemblies to store and access information.

BIM Modeling Application’s Managed Graphics Class Library was rewritten to run in the.NET framework allowing the development of.NET based applications in AutoCAD. This model was used to allow the functionality of the following applications to be developed and easily integrated into AutoCAD:

AutoCAD XML is a proprietary XML-based programming language developed by Autodesk. It uses a subset of XML called Autodesk Markup Language (AML) and is an object-based notation using complex data structures, though also allowing simple data.

In AutoCAD, “XML” is a macro language. It supports creation of “XML macros” with object capabilities that respond to events in the AutoCAD environment. The XML macros of AutoCAD 2008 run as a “visible component” in the AutoCAD environment. They have their own command-line interface (CLI), and you can “publish” macros from the CLI using the same UI as the CLIs of conventional macros.

AutoCAD 2010 introduces support for XML concepts including XML nodes, node types, and data types. It also supports markup languages such as Web Markup Language (WebML), UML, and Software Manifestation Language (SMAL). It supports an XML stylesheet language based on XML Schema (XSD) such as AutoCAD XML Schema (AXMLS), a subset of XML Schema.

AutoCAD supports a programming interface for users to perform tasks using XML. This interface has been expanded and supports more tasks in AutoCAD 2011.

AutoCAD was first developed by C-Cube Microsystems, and was originally released in 1992 as AutoCAD for Microstation, a product from the company’s CAD/CAM group (later Autodesk) for the Microstation product line of the Thomas Software Corporation (now Siemens PLM Software). In 1996,

How to prevent duplicate inserts on Postgresql?

I’ve got a simple select statement.
I insert data to the table in a loop.
So the data I want to insert looks like this.
insert into table1 (…)

The problem is that every call to my function happens at the same time so i will receive “duplicate key value violates unique constraint” when i run my application.
I know that the easiest solution would be to make my function blocking. Then i will have to check if the data is already inserted in the table with a query, but it makes the function more complicated.
Also I’ve read something about the transaction isolation level. If i set it to serialized, would my data be inserted in a transaction? How?


You can use a DO $$ as a local context, and not worry about transactions or locks:
DO $$
DECLARE insrc cursor for
SELECT * FROM table1;
OPEN insrc;
FETCH NEXT FROM insrc into mydata;
WHILE(FETCH NEXT FROM insrc into mydata) DO
INSERT INTO table1 (… ) VALUES (… );
