青蛙和蛤蟆的区别:关于linux系统上的CAD软件

AutoCAD R13在Unix平台上的一些问题
当Autodesk停止开发支持Unix平台的应用程序时，Unix的硬件和软件还在继续发展。在没有被测试的操作系统上运行AutoCAD或其他应用程序的负面影响有时很小，但有时也会导致灾难。至于R13 for Unix遇到的最大问题是关于mole模式的数字化仪和图形的驱动程序。这里就是一些我们已知的问题：
在R13C4问世不久后由SGI公司发布的IRIX 6 系统现在已经成为SGI系统上的主导操作系统。AutoCAD被开发测试的IRIX版本是5.3。如果尝试在一个安装了IRIX6的64位SGI系统上安装AutoCAD Mole模式驱动程序，操作系统就会严重崩溃，以致于损失启动盘上的所有数据。
至于HPUX 10.2系统，mole模式驱动程序不能在其上运行。R13c4是在HPUX 10.01上测试发布的。现在惠普公司正在发布HPUX 11系统。
R13c4 IBM 端口版本是基于4.1.2系统上发布的。在4.1.3系统上，所有程序都运行的很好。但在4.1.4系统上许可管理程序显示出不正常，冗余许可服务特征被拒绝在其上运行。IBM现在正在进行发放AIX4.2系统。
在Solaris 2.5.1系统上AutoCAD在运行“Save as”命令覆盖文件时就会崩溃。R13c4是在2.5.0系统上发布的。
下面，我们列出R13 所支持的Unix平台操作系统，
操作系统 最小支持版本 最后测试版本
AIX 4.1.2 4.1.2
HP-UX 9.01 10.1

AutoCAD is a CAD (Computer Aided Design or Computer Aided Drafting) software application for 2D and 3D design and drafting, developed and sold by Autodesk, Inc. Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers.
In earlier releases, AutoCAD used primitive entities — such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools. With the release of AutoCAD 2007 came improved 3D modeling functionality, which meant better navigation when working in 3D. Moreover, it became easier to edit 3D models. The mental ray engine was included in rendering, it was now possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and mesh modeling.
AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.
AutoCAD currently runs exclusively on Microsoft Windows desktop operating systems. Versions for Unix and Mac OS were released in the 1980s and 1990s, but these were later dropped. AutoCAD can run on an emulator or compatibility layer like VMware Workstation or Wine, albeit subject to various performance issues that can often arise when working with 3D objects or large drawings.
AutoCAD and AutoCAD LT are available for English,German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified, Chinese Traditional, Russian, Czech, Polish, Hungarian, Brazilian Portuguese, Danish, Dutch, Swedish, Finnish, Norwegian and Vietnamese. The extent of localization varies from full translation of the product to documentation only.
Autodesk, Inc. (NASDAQ: ADSK) is an American multinational corporation that focuses on 2D and 3D design software for use in architecture, engineering and building construction, manufacturing, and media and entertainment. Autodesk was founded in 1982 by John Walker, a coauthor of early versions of the company's flagship CAD software product AutoCAD, and twelve others. It is headquartered in San Rafael, California.
Autodesk has arguably become best-known due to its flagship computer-aided design software AutoCAD. Today, Autodesk is the world's largest design software company, with more than 9 million users throughout the world, and the company was recently named number 25 on Fast Company's list of "The World's 50 Most Innovative Companies."
Autodesk has developed a broad portfolio of digital prototyping solutions to help users visualize, simulate, and analyze real-world performance throughout the design process. The company also provides digital media creation and management software across all media and entertainment disciplines, from film and television visual effects, color grading, and editing to animation, game development, and design visualization。

I'm trying to find out if it's possible to install Autodesk (AutoCAD) Inventor 10 on a Mac via UNIX. I need to use the 3-D modeling CAD software for work, but I would really like to run it on a new Intel powered 20" iMac. Autodesk does not currently make the software for Mac, so when I asked the "Gurus" at my local Apple store they said it's possible if I knew how to compile the software to run on OSX's version of UNIX.
Does anyone know if this really is possible, and if so how would I go about doing it?
I appreciate any advice.

It seems to me that AutoDesk Inventor is a commercial product and as such, it is not available in source code form. I guess the people you asked about this didn't realize that you were asking about a commercial product.
According to this AutoDesk page, it only runs on Windows:
http://usa.autodesk.com/adsk/servlet...112&id=5182483
You should contact AutoDesk to see if they plan to make an OS X version.
Of course, you could try running it under Virtual PC, but that likely will be too slow.

yeh.... Autocad is Windoze only.... and that is kinda that...
Vectorwork is a GREAT alternative and is cross platform.... it integrates pretty seamlessly with AC too...
if you have to run AC check out this website..... http://www.macwindows.com/... it has alot of users using it under VPC or RDC and will give you a few pointers
  
how Autodesk's AutoCADwas made to run on a GNU/Linuxmachine ---怎样让AutoCAD在LINUX上运行

Look Ma ...
No Windows!!!
Many architects believe that they cannot migrate their IT systems away fromMicrosoft(tm) Windows(R) and embrace GNU/Linux like all other professions are free to do.
A small practice in Johannesburg, South Africa, is doing it without Windows. We interviewed the senior partner to find out why and how Autodesk's AutoCADwas made to run on a GNU/Linuxmachine .
Read on ...

There is a small architectural practice in Melville, Johannesburg, that has done the unthinkable: removed all Microsoft software from their machines and replaced it with Free and Open Source alternatives.  The only proprietary software which they still run are old AutoCAD R14 licenses built for the Microsoft Windows platform - and they run it inside GNU/Linux.
This is a transcript of an interview conducted by Architect Africa and the practice's senior partner, with the questions excluded for brevity.
"We didn't do it so save money. That's a common misunderstanding about Free Software. We did it because it offers us a better solution all round. The fact that it has saved us some money is a bonus.
The practice has been running on dual systems (Windows and GNU) for some years but the majority of the desktops and CAD workstations were Windows machines because we are very fond of AutoCad and AutoCad has only ever been released for the Windows operating system. That was the only stumbling block in crossing over to the Unix camp...
We like AutoCAD R14 because it's paid for, because we are used to it and because we can use it effectively and productively. I've been using AutoCAD for over 10 years and wouldn't dream of changing now. Why? For us it is a drafting tool, nothing more. It works. Our 14's are as good as your common garden variety 2000's or whatevers; we've added on our own commands and modules over the years and nothing we could buy now would improve on our system... Quite the opposite.
We don't run 3D software. That's for people who have a problem drawing with a pencil and a piece of paper. The computer has a very long way to go before it can replace the architect's hand. In our practice we do our 3D's and models by hand in the physical world. It works better for us that way and being from the old school, we can draw ... which helps.
But that too is set to change in the next two or three years when Autodesk hopefully releases a GNU/Linux version of Revit. We would buy that. But we wont be holding our breath. Revit is ahead of my time and needs its edges tweeked a bit. We can wait, or maybe something similar pops up at a quarter of the price before that...
We're not exactly happy about running old Acads - it's an interim measure. We've been looking at a German GNU/Linux clone of AutoCAD which is quite impressive and very cheap. Maybe we will go that route. For now AutoCad R14 is what keeps our office in business.
It was decided in 2002 that we would run both operating systems in the practice until we had tested and liked a GNU/Linux AutoCad clone that made economic sense and could improve on the old R14's.
Then, a couple of months ago, I got a call from a very brash lady who claimed to be calling from Microsoft South Africa. I didn't like her attitude or her veiled threats to invade my office and confiscate my computers - which she assured me she had the legal right to do.
I asked her to send me a letter explaining her company's position, which she did. That letter together with theBusiness Software Alliance adverts on TV made me realise how vulnerable my practice had become to external mercenary threats and the willy nilly policies of American corporations. I was being called a pirate and they were behaving like bounty hunters. It was ugly, I thought.
We had a variety of MS-Office packages running on all the AutoCAD workstations and all our admin machines on Open Office and the odd Star Office as well. We also had a large cardboard box with years' worth of licenses and certificates. It would have taken us weeks to go through all those pages and pages of legal mumbo jumbo. It was easier to delete all MS-Office installations and replace them with Open Office. Which we did.
To compound the problem we knew that the part time students that we employ are forever installing their own (usually pirated) software on our machines. Other CADs, graphics software, etc. We could have a ton of illegal software on the network, not know about it and still get fined for it.
That particular concern got us going and we decided to go all the way and get rid of the operating systems as well and then burn the cardboard box full of licenses. To do that we needed to find a way of running R14 in Debian GNU/Linux.
We thought this would be a stumbling block but it turned out to be the opposite - not only did we get AutoCad R14 running on Debian GNU/Linux within 24 hours but it actually ran faster! Can you believe that?
The advantages are astronomical and the savings substantial. With a GNU/Linux backbone we have great stability, uniformity, control and scalability. The security aspect is also greatly enhanced and we are now immune to viruses which are mostly geared towards attacking Microsoft operating systems. That's a big plus for us as our CAD workstations are equipped with email and FTP to ship off drawings and documents through the Net. That meant that we suffered regular virus attacks ... often with serious consequences and long periods of down time.
Another great plus is that our student workers can't install their illegal stuff on our machines and put us at risk. That is over and I feel good about that particular aspect
I can say that this migration has worked well for us because we planned it with time and care. I'm sure it's not for everyone and I don't recommend that you rush to burn your licenses and ditch your software. You can't rush these things. It's like software updates - sometimes they cause more disruption than good. So take your time - but do it.
Our network is our most valuable resource and our most valuable asset. We like to take good care of it and we like to keep outsiders away from it. Now, for the first time ever, we can say that we truly own it and control it. We are proudly a GNU practice - a Free Practice. "
Roll on freedom ...



 How is it done?
A Johannesburg FOSS (Free and Open Source Software) company used the package Wine, tweeked it and installed it on Debian GNU/Linux.
Wine is an Open Source implementation of the Windows API on top of X and Unix.
Think of Wine as a Windows compatibility layer. Wine does not require Microsoft Windows, as it is a completely alternative implementation consisting of 100% Microsoft-free code, but it can optionally use native system DLLs if they are available. Wine provides both a development toolkit (Winelib) for porting Windows sources to Unix and a program loader, allowing many unmodified Windows binaries to run on x86-based Unixes, including Linux, FreeBSD, and Solaris.
More information can be read in the articlesWhy Wine is so important, and Debunking Wine Myths.
The licensing terms are the GNU Lesser General Public License.
If you have no Unix experience you are better off using the commercial counterpartCross Over Office which works off the box. It costs around US$60 per seat. It's an excellent product. Try it for free.
Although we much prefer the Gimp you can also run Photoshop in Wine and CrossOver.

as well as MS-Office and Multi-Media ...

Linux CAD Software
Information about Linux CAD Software. Visit the following links for more information about Linux CAD Software.
Linux CAD
LinuxCAD is today's leading computer aided design and drafting program for The Linux Operating System. LinuxCAD has grown in sales and functionality since its original introduction in 1998. LinuxCAD now represents a complete computer aided design program for Linux ... it is a complete replacement for AutoCAD. For any practical purpose, it implements all major features of AutoCAD in such a way that experienced AutoCAD users do not need additional training to start working with LinuxCAD. Linux users who are new to CAD will find our Users Manual an easy way to learn the CAD trade. There is so much similarity between LinuxCAD and AutoCAD, that while learning LinuxCAD, you will simultaneously learn AutoCAD.

AutoVue is a visualization and collaboration Viewing and Markup software which can natively view over 200 different document formats including Pro/ENGINEER, AutoCAD, MicroStation, CADKEY, CATIA, Inventor, Mechanical Desktop, SolidWorks, SolidDesigner, Solid Edge & STEP. A JAVA thin-client version is available. A fully functional evaluation versions of all programs are available for download.
My CAD Software
EDA: - An EDA application is used for drawing schematics, PC-boards and the like. This list is likely to be undergoing drastic changes in the next while as I revamp my EDA suite. Oregano: - Nice little Linux-based schematic capture and simulation package using spice. Kind of buggy, and has been discontinued in favor of GAEL. Which is sort-of a shame, because GAEL is still very early alpha. KLogic: - KLogic is a cute little Linux-based interactive schematic capture and digital simulation package. Handy, but I don't really use it anymore. TkGate: - TkGate is a much more powerful interactive circuit layout/simulation package. It does basically everything that KLogic does, plus it saves Verilog files and has a much more powerful simulator for complex digital designs. Eagle: - Powerful program for schematic capture and PC-board layout, for both Linux and Windows (I use both interchangably). This has been suggested to me a dozen times, right after I actually started using it. It's a nice program, but it's not exactly free. I'm currently investigating other options.
The GNU/Linux DVD Player Review
Jon takes a look at Xine, VideoLAN Client, MPlayer and Ogle--four GNU/Linux DVD playback applications.
Playing DVDs under GNU/Linux has not had the happiest of histories, what with the DeCSS debacle and subsequent legal battle. So you'd be forgiven for thinking that you will never be able to play your DVDs on your GNU/Linux system. Luckily, this is not the case, and there are several applications available for you to download and use. The issue with DeCSS is still with us but is slowly getting clearer. However, this has left some of the DVD players officially not supporting encrypted DVDs, although unofficially, playback is possible via third-party additions.
CAD/CAM Application
Linux is available in several formats, called distributions. Each distribution has its own set of features and functionality that makes it unique -- some distributions are available for download at no charge, others are provided on CD or floppy disk and have a (usually) nominal charge associated with them. In each section below, you'll find not only a list of applications, tools, and utilities, but links to web sites providing support, reviews, and other useful information.
CAD for Linux
CADforLINUX beta testing period is finished, we want to thanks all people have support us on this development. Next step will be merge new source code (from progeCAD 2006) into Linux project. From a long time, CAD users ask to have a powerful DWG tool on GNU/Linux. With this new product, ProgeSOFT offers a new important, standard application for Linux, the natural complement of other office applications.
CADforLINUX is a powerful and complete 2D/3D CAD environment, 100% compatible with DWG drawing format, developed in order to run on GNU/Linux distributions.
Linux substitutes for "most wanted" Windows-only software
DesktopLinux.com has reported recently on Novell Inc.'s survey of the "most wanted" Windows/MacOS-only applications among Linux users. As a result of over 14,000 votes and comments that have been registered since the beginning of January, some useful suggestions about good Linux substitutes have come to the fore. "All the feedback and participation has been great thus far. As the survey continues, I wanted to share some of the suggestions that people have made regarding the top-requested applications. They have been both impressive and helpful," CoolSolutions site editor Scott Morris said.
Free and cheap CAD
This page is devoted to free or cheap Computer Aided Design software.Many years ago now I worked as a mechanical engineer, using SDRC IDEAS (briefly), Pro-ENGINEER (quite a bit) and AutoCAD (a lot on version 10 in the distant past, and briefly on 12). Now I'm a publisher and just using (mostly 3D) CAD as a hobby. So I developed an interest in (legal) CAD software which is cheap, or, even better, free!When I wrote this page originally, I was looking for software to design bicycles and other human powered vehicles, but should be relevant for many other users too of course. If you are designing bicycles or HPVs on CAD, check out the IHPVA Parts Library and please do contribute anything relevant which you draw.
Linux for CAD
Linux has made big headway in business, but so far almost entirely as a back-room network file-server serving workstations that run Windows. The main problem is that everyone wants to run the 慽ndustry-standard? application programs that require Windows. I decided to use an HP Pavilion 8509. This is a domestic-market PC that runs CAD very well. It has a Pentium-III 450MHz CPU and came with 64 Mb RAM, which I upgraded to 288Mb. It had an 8Gb drive set up as a single C drive and Windows 98SE. I wanted to use this PC to try out Linux while keeping Windows, as many people will want to do that. After much deliberation and asking friends about slide-in drive trays etc, I decided to install Linux on a second hard disk.
Use of Unix CAD software
CAD software is supported for use on the Shackleton building SUN SPARCstations running the Solaris 2 Unix operating system.The software also runs on the ECS department's CAD server, salvador, although not all students are permitted to log onto salvador directly. Some users may feel that the enforced uniformity of the CAD setup cramps their UNIX style. If you are one of these users, you can run CAD tools via the CAD environment called from any terminal window using: ~bim/script/CAD. In this case you will have to run the CAD environment any time that you want to use CAD tools. This method is NOT guaranteed to work since all CAD tools are tested with the standard setup and not with this special CAD environment. Note that you could incorporate commands from the ~bim/script/CAD script in your own startup files to avoid having to remember to type the command every time. In any event if you chose to brand yourself an expert user you will have to take more responsibilty for any problems you encounter. It is usual for problems to be dealt with only after they have been demonstrated on a standard CAD setup.
Linux Invades Hollywood
Shrek was the first major motion picture created primarily using Linux. It won't be the last. Linux is rapidly becoming the professional animator's operating system (OS) of choice, not just at DreamWorks SKG, which produced Shrek, but at top production studios in Hollywood, the Bay Area, and London. An OS that started 10 years ago as a Finnish college student's personal hobby-not even a university research project-is invading film industry servers, renderfarms, and workstations.Film animators are now using Linux versions of Alias|Wavefront's Maya, No thing Real's Shake, Side Effects' Houdini, and Pixar's RenderMan-the leading commercial applications for animation, compositing, special effects, and rendering.
New Betas of CAD Software
General CADD Pro v2.1.37 (and list of fixes) can be downloaded from here. The beta of General CADD Pro v3.0.12 is also available for testing and download. Check out the new user-customizable toolbars, spell checker, and the new GT and OT commands. A discussion forum is here.You can download the beta release of BricsCAD v5 for Linux from here. On the download page, you find a new trial license key for BricsCad V5 for Linux, valid until end of September 2004.BricsCad V5 improves performance, and contains more than 200 fixes -- including numerous fixes and improvements related to running on WINE.
Another Reason for the Linux CAD
There are many, many, reasons for translating information from one language to another, that go way beyond Docs and 揗arketing?. I use them almost every day for many different reasons. But if your argument is that their English 揗arketing? materials should be up to par, than, to be fair, I must though it back to you as well. In the original posting did it mention that this was a computer translation (for which it clearly is), nor any of your arguments about open source software, or anything about the lack of proper 揈nglish? documentation stated most recent post. It only seemed to say: Look how bad this English is, and this is why Linux CAD has not caught on...That is at least how I interpreted your original article and why I asked for clarification, thank you for your clarification.
Compiling PUFF microwave CAD software on Linux
The PUFF software is available for sale together with a book from the California Institute of Technology, and in Europe from UKW-Berichte. Although it is not free, it is quite cheap compared to other software; furthermore, in many cases it comes with with source code written in Turbo Pascal. (Note: since making this web page available, several people have told me that their copy of the floppy disk did not contain the source code. I do not know details, so for the moment I can only advise you explicitly ask for the source code before ordering.) The fact that PUFF comes with source code makes it possible to port it to other systems than the original MS-DOS. Using the Free Pascal compiler, most of the original Turbo Pascal code compiles without problems on Linux.
The SynDEx - System-Level CAD Software
Distributed real-time embedded systems are of crucial importance in application domains such as avionics, automobiles, telecommunication and mobile robotics. Principally based on digital electronics, which includes software, this aspect of the various applications is rapidly growing. Because they must meet constraints on resource distribution and optimization, as well as time, the design of such systems is particularly complex. In order to assist the designers, scientists at INRIA are proposing a methodology called AAA (Algorithm Architecture Adequation) and its associated system-level CAD software called SynDEx. These cover the whole development cycle, from the specification of the application functions, to their implementation running in real time on a distributed architecture composed of processors and specific integrated circuits.

AutoCAD Version
AutoCAD Version Explorer (AVE) is a quick way to check version information on AutoCAD files in an Explorer-like interface. AVE also has the ability to display the preview image from version 13, 14, 2000/2000i/2002 & 2004/2005/2006 files. Features:- 1. Display version (v2.5, 2.6, 9, 10, 11/12, 13, 14, 2000/2000i/2002, 2004/2005/2006) 2. Display preview images (v13, 14, 2000/2000i/2002 & 2004/2005/2006)
3. Output selected files or entire directory to HTML format. 4. Create zip files from selected files or entire directory. 5. Display 3X view and various file management options by right-clicking a file.
About Linux
Linux is a free UNIX like operating system created by Linus Torvalds with the help of developers all around the world. Linux is freely available for everybody thanks to it's GPL licence. You can lurn more about Linux by reading the FAQ, or a more complete introduction to Linux. The best way to install Linux if you have never used it before would be to buy a complete Linux distribution. It includes Linux itself, usefull software, some documentation and generally a 30 days support. You can get these usually for a cheap price (arround 30-40 ). You can buy Red Hat Linux 9.0, or SuSE Linux from Amazon, both are good distributions. Mandrake Linux PowerPack Edition 9.1 is also known to be one of the most simple Linux distributions to install and to use.

A CAD system is a combination of hardware and software that enables engineers and architects to design everything from furniture to airplanes. In addition to the software, CAD systems require a high-quality graphics monitor; a mouse, light pen, or digitizing tablet for drawing; and a special printer or plotter for printing design specifications. Until the mid 1980s, all CAD systems were specially constructed computers. Now, you can buy CAD software that runs on general-purpose workstations and personal computers.
About VUTRAX
VUTRAX (pronounced View-Tracks) is the major professional Electronics schematic and PCB (Printed circuit board) design package in the UK. The product was the first EDA package offered for personal computers, having a pedigree back to 1981 when it was created for use by in-house draughtsmen. This modern product offers similar functionality to formal workstations but at a fraction of the cost. There are now thousands of systems in use worldwide designing boards used from the seabed to satellites.VUTRAX is available now for Windows 95, Windows 98, Windows ME, Windows NT 3.51, Windows NT 4.0, Windows 2000 and Windows XP.
Virtual Reality Visualization of CAD Data
CAD/CAM software plays an integral role in nuclear power plant design. However, CAD/CAM software leaves some major issues in the design process unaddressed. We seek to fill the gap through the use of a virtual reality representation of the plant. Through the use of virtual reality, we plan to investigate the integration of components during construction. Unforeseen problems during construction often require field changes that introduce delays. In addition, virtual reality can be used for the training of plant maintenance personnel. The model we are using for proof-of-concept is a CAD generated model of the AP600 plant. The original AUTOCAD dxf file was passed through a filter to produce a data file compatible with our VR software. We have also developed a methodology for producing virtual models from PRO/E.
