CAD. 456 From 1. Aplikasi Gudang Gratis Full. Autodesk created versions of Auto. CAD which wrote no fewer than 1. DWG file format,7 none of which is publicly documented. The DWG format is probably the most widely used format for CAD drawings. Autodesk estimates that in 1. DWG files in existence. There are several claims to control of the DWG format. As the biggest and most influential creator of DWG files it is Autodesk who designs, defines, and iterates the DWG format as the native format for their CAD applications. Autodesk sells a readwrite library, called Real. DWG,1. 0 under selective licensing terms for use in non competitive applications. Several companies have attempted to reverse engineer Autodesks DWG format, and offer software libraries to read and write Autodesk DWG files. The most successful is Open Design Alliance,1. Autodesk, released a readwriteview library called the Open. DWG Toolkit, which was based on the Mar. Comp AUTODIRECT libraries. ODA has since rewritten and updated that code. In 1. Autodesk added file verification to Auto. CAD R1. 4. 0. 1, through a function called DWGCHECK. This function was supported by an encrypted checksum and product code called a watermark by Autodesk, written into DWG files created by the program. In 2. 00. 6 Autodesk modified Auto. CAD 2. 00. 7, to include Trusted. DWG technology, a function which would embed a text string within DWG files written by the program Autodesk DWG. This file is a Trusted DWG last saved by an Autodesk application or Autodesk licensed application. This helped Autodesk software users ensure that the files they were opening were created by an Autodesk, or Real. DWG application, reducing risk of incompatibilities. Auto. CAD would pop up a message, warning of potential stability problems, if a user opened a 2. DWG file which did not include this text string. In 2. 00. 8 the Free Software Foundation asserted the need for an open replacement for the DWG format, as neither Real. DWG1. 0 nor DWGdirect are licensed on terms that are compatible with free software license like the GNU GPL. Therefore, the FSF placed the goal Replacement for Open. DWG libraries in 1. High Priority Free Software Projects list. Created in late 2. GNULibre. DWG1. 8 is a free software library released under the terms of the GNU GPLv. Despite being currently under development, it can read most parts of DWG files from version R1. Also in 2. 00. 8 Autodesk and Bentley Systems agreed on exchange of software libraries, including Autodesk Real. DWG, to improve the ability to read and write the companies respective DWG and DGN formats in mixed environments with greater fidelity. In addition, the two companies will facilitate work process interoperability between their AEC applications through supporting the reciprocal use of available Application Programming Interfaces APIs. Autodesk trademarkeditOn 1. November 2. 00. 6, Autodesk sued the Open Design Alliance alleging that its DWGdirect libraries infringed Autodesks trademark for the word Autodesk, by writing the Trusted. DWG watermark including the word Auto. CAD into DWG files it created. Nine days later, Autodesks attorneys won a broad and deep temporary restraining order against the Open Design Alliance. In April 2. 00. 7, the suit was settled, essentially on Autodesks terms, with Autodesk modifying the warning message in Auto. CAD 2. 00. 8 to make it somewhat less alarming, and the Open Design Alliance removing support for writing the Trusted. DWG watermark from its DWGdirect libraries. The effect of the temporary restraining order and subsequent consent decree was to render the Open Design Alliances DWGdirect libraries, from one point of view, incapable of creating DWG files that are 1. Auto. CAD. Others point out that the failure of 1. Auto. CAD. 2. 2In 2. Autodesk applied for registration of US trademarks on DWG,2. DWG EXTREME,2. 5 DWG TRUECONVERT,2. REALDWG,2. 7 DWGX,2. DWG TRUEVIEW. 2. As early as 1. Autodesk has disclaimed exclusive use of the DWG mark in US trademark filings. Out of these applications, only TRUSTEDDWG has been registered as a trademark by the USPTO. The REALDWG and DWGX registrations were opposed by Solid. Works. The DWG EXTREME, DWG TRUECONVERT, and DWG TRUEVIEW trademark registration applications all received substantial resistance, with the USPTO examining attorney requiring Autodesk to disclaim exclusive use of DWG as a condition for their registration. In a non final action in May, 2. USPTO examining attorney refused to register the two DWG marks, as they are merely descriptive of the use of DWG as a file format name. In September, 2. 00. Autodesk responded, claiming that DWG has gained a secondary meaning, separate from its use as a generic file format name. As of June 2. 2, 2. Autodesks DWG related trademark registration proceedings were suspended by the USPTO, pending disposition of trademark opposition and cancellation petitions Autodesk had filed against the Open Design Alliance and Dassault Systmes Solid. Works Corporation. The USPTO office actions notifying Autodesk of this noted that Autodesk was not the exclusive source of files with the format name DWG, and Autodesk does not control the use of DWG by others, either as a trademark or as a file format name, among other points. In 2. 00. 6, Autodesk filed an opposition with the USPTO to the trademark registration of DWGGATEWAY by Solid. Works. 3. 3 Autodesk subsequently filed a petition for cancellation of Solid. Works trademark registration for DWGEDITOR. In both cases, Autodesks basis was that they had been using the DWG name with its CAD software products since at least as early as 1. The opposition and cancellation actions were consolidated, and suspended pending disposition of Autodesks US District Court suit against Solid. Works. 3. 5In early 2. Download VBA VB code for Auto.
