AutoCAD 2002 and the Internet


AutoCAD 2002 includes tools that allow drawings and special plots to be posted to the internet.  These tools make it easy for multiple design companies to collaborate on one set of project files through an internet server rather than relying on dividing project files and sending them by email.

There are three types of files that you can use to transfer AutoCAD data to the internet for other users to see: native DWG files, compressed DWF files, and raster images.

AutoCAD DWG Files
AutoCAD DWG files may easily be saved to a web server for access by other companies.  The AutoCAD OPEN and SAVEAS functions allow drawings to be saved to internet sites and project hosting servers, simply by selecting the appropriate web server from the open/save as dialog box.
Pros Cons
Clients who receive the drawings can look at the data using AutoCAD, ADT, Map and LDD, and use AutoCAD functions for data analysis. Data in DWG files may be edited and plotted.  No data protection mechanism exists.
Drawings may be plotted to scale, and plotting properties may be modified using AutoCAD commands. External References and support files will have to be saved to the web server and managed by mulitple clients.  However, the eTransmit command assists with this task.
i-drop functionality allows drawings to be inserted into AutoCAD applications from web servers. Only clients with AutoCAD products may read DWG files.

Drawing Web Format (DWF) Files
DWF Files are vector files that are compressed versions of DWG files, designed to make transfer and viewing of AutoCAD data through the internet much easier.  Clients who do not have AutoCAD may use their web browsers to look at AutoCAD drawings, zoom and pan around them, turn layers on and off, or even print them to scale.  See the web page Viewing DWF Files for more information on all the features available in the DWF format.

Two software programs are available to view DWF files.  Volo View Express is a free DWF and DWG viewer that can view AutoCAD 2002 drawings in 3D, draft markups on top of the drawing, and plot the drawing to scale.  Volo View Express (VVE) is available from Autodesk's web site free of charge.  Click on the VVE logo on the right to download it.  VVE may also be installed at the time of AutoCAD 2002 installation.  Double-click on a DWF file to view it through VVE, or select a DWF file to view with a web browser to use VVE functionality.   VVE must be installed to look at DWF files created in AutoCAD 2002.

DWF files created in AutoCAD 2000 or 2000i may be viewed through your web browser.  To view a DWF file using your web browser, you need to download and install a driver from Autodesk called Whip! Release 4.0.  The Whip! driver is automatically installed if you have AutoCAD 2000 or 2000i installed on your machine.  Click on the Whip! logo to download the free software.  Once you have installed the Whip! driver, you can go to a page with a DWF file on the internet to look at the drawing.   See the page titled "Viewing DWF Files" to see a sample of how a DWF file appears on the internet.


Pros Cons
Any client with a web browser or Volo View Express (available free of charge) can read DWF files. No AutoCAD functionality.  Inquiry commands such as DISTANCE or AREA are not available.
DWF files may not be edited.  Data sent away from the office is protected from modification by clients. DWF files may not be externally referenced or combined in any way.
With VVE, DWF files may be plotted to scale, and lineweights may be used for plotting.
Layers, views, and hyperlinks may be manipulated in a DWF file. 

Raster Images
Raster images are digital photos of AutoCAD Drawings.  To create raster images, run the PLOT command, and select a PC3 file that plots an image to a file.  Images may be created from model space or any of the layout tabs in a drawing.
Pros Cons
Easy to read from web pages.  JPG and WMF files may be inserted into other applications (word processors, spreadsheets). The raster image is made of pixels, so object information is lost.  Layer settings may not be adjusted.  Inquiry functions not available outside of AutoCAD.
May be inserted into AutoCAD drawings.  AutoCAD vector objects may be drawn over images to create hybrid documents. Images can be edited using CAD Overlay or other image editing software.  Data is not protected.
Images cannot be plotted to an exact scale.  Using AutoCAD, images can be correlated to an approximate scale.
