The Disadvantages of CAD

A couple of issues ago, Jamie Wilkes asked for help in learning about the disadvantages of implementing CAD. Says Jamie: "I received a good response. From the information received I have compiled a questionnaire at: http://members.tripod.co.uk/jswilkes/questionnaire.html "

Here are some of the responses that Jamie received:

"I'd like to offer a list that, for the most part, are a direct result of giving up "hand drafting" (or draughting <wink>, as I am a displaced Englishman) from a 16-year veteran:

         - Paul Freeman

"I think the biggest disadvantage of CAD is the loss of spontaneity. With a pencil and paper, you can scribble as fast as you can move your hand while your mind is processing the ideas that are hidden in the scribbles. This allows for many more design related thoughts before a single hard line is put to paper. This process is vastly slowed down with CAD. Due to the easy ability to 'snap' endpoints, etc., CAD almost forces you to a level of detail that paper and pencil save till the presentation or construction documents require."
         - Robert Visser,

"One that's common to most CAD operators is that they seem to be using CAD (expensive here in Malaysia until the introduction of AutoCAD LT and IntelliCAD) as a "copying machine": line, trim, extend, erase -- the way these commands are used is mimicking the manual drafting. There are drawings completed with multi-color and in a single layer! The drafting department does not implement strict CAD layering and procedures.
         "What engineers and architects want out of the CAD operators are the plotted 2D drawings - the purpose? To submit for authorities approval. If only the authorities insist on the DWG file! Do you know that over here in Malaysia, most CAD operators find it very difficult to continue even his/her neighbour's drawings? Because the lines and text are not organized, they rather start over again, and plotting will even be easier!"

Update on VersaCAD

Tom Lazear writes: "We are still madly working on a Windows version of VersaCAD. It turned out that the existing, debugged source code would not compile on today's compilers: lots of syntax rules had changed in the six years since VersaCAD was last compiled. That set us back a couple of months, since VersaCAD is on towards 1,000,000 lines of C.

"That is behind us now, and we are actually beginning to see results. We hope to have a beta this month.

"Our biggest marketing effort is still to find existing VersaCAD users. We find four or five new ones every day. We have found over 1,000 entities still using VersaCAD. They come from Germany, Switzerland, France, Asia, South America, and all over the USA. Many say they purchased other CAD, but always come back to VersaCAD when the crunch comes to get the drawings out.

"We are still hopeful that we will have enough existing users willing to pay a maintenance fee that we will get enough revenue to pay to keep VersaCAD up to date. We already have 80 companies that have paid "on the come" for the new Windows version, and we have 500 email addresses of others who said they will be interested when we are actually shipping.
 The fee for maintenance is US$595 per year for the first seat, and US$100 per year per seat for additional seats. We are looking forward to updating them to the Windows version. The Mac version is looking good."


ITC Developer Conference

The IntelliCAD Technology Consortium last month hosted a  developer conference for ITC commercial members. Developers from ten companies met with the Visio developers who had worked on IntelliCAD. Topics covered included VBA, TrueType fonts, Boundary Hatching, MTEXT, and low-level issues such as threading, the entity database, graphics display, and geometric utilities.

Also discussed were immediate plans and future directions which include hiring a team of programmers to work on further development.  Martin Waardenburg of Bricsnet announced his companies desire to manage the development project. It is expected that commercial versions of IntelliCAD 2000 should be ready by the end of January 2000.


LandXML

Autodesk and Intergraph are working with several agencies and consulting firms to develop LandXML for software involved in land planning, civil engineering, and surveying.

LandXML is based on the EAS-E (short for "Engineering and Survey - Exchange") Initiative, which defines an ASCII data format for highway design projects.

Technical details on the LandXML Schema are found at http://www.biztalk.org/Library/SchemaDetail.asp?SchemaID=532902%20  [I wonder why Autodesk didn't do MechXML -- or has someone already? - Ed.]

In the meantime, the aecXML initiative (started by Bentley Systems) has merged with the IAI.

Life with Linux, Part II:

Installing the Software -- the Theory

From my experience with OS/2 and Unix in the late 80s, I knew that installing a second operating system is tricky. The computer's hard disk needs to be partitioned (sort of like adding a dividing wall to a room); partitioning erases all data from the drive. Needless to say, I was not looking forward to this. I decide to wait a day to think about which computer to install Linux.

Wed 6 Jan -
I finally receive an email reply from corel@techwave.com: "We are not currently showing a charge against your credit card for an order placed today nor can we find any order information." They seem disinterested in the bug I found on their Web site that prevented the order from going through.

I spend the morning reading the User Guide. I spend the most time reading and re-reading pages 22-28, which describe the four installation options:

Options 1 and 2: Install Linux as the only operating system. Option 1 is for when no operating system exits; option 2 replaces the existing operating system by reformatting the drive.

Options 3 and 4: Add Linux to an existing operating system. Option 3 requires the hard drive to have at least two partitions; option 4 allows co-existence without a partition.

After spending all morning mulling over the options, I decide option 4 is for me. Trouble is, the other three options warn of full and complete data loss; option 4 fails to make it clear that it involves no data loss. Option 4 is the best if you just want to experiment with Linux.

The manual fails to make clear what I later found out: option 4 installs Linux in a subdirectory called CDL. Among other files, the directory contains a pair of IMG files (root and swap), which I assume simulate a drive partition for Linux. To start Linux, you first start Windows; exit to DOS; then start a batch file that launches Linux. To remove Linux, you simply erase the CDL directory.

From my experience, these are the steps I took to install Corel Linux using option #4:

Step 1. Confirm that my computer meets the hardware requirements. These include a Pentium CPU, PCI graphics, minimum 500MB free disk space (a couple of GB is better). Check for hardware compatibility: Corel has a 55-page list of compatible hardware products at http://linux.corel.com/products/linux_os/hardware.htm . While Corel Linux works with most common hardware out there, it does not boot with some important drives, such as PC Card drives, parallel-port CD-ROM drives, and ultra DMA 66 hard drives (the UDMA 66 can be used as a non-booting drive with Linux).

Step 2. Decide if Linux will replace Windows or co-exist with Windows. Back up all data on the hard drive.

Step 3. Use ScanDisk to remove any errors from the hard drive.

Step 4. Use Disk Defragmenter to defrag the hard drive. For a multi-GB hard drive, this can take several hours.

Step 5. Reboot the computer, pressing DEL to access the BIOS setup:

Step 6. Insert the Linux CD-ROM, and reboot the computer. The Corel Linux installation takes over. Choose the type of installation (as per Step 2), and select the hard drive for booting Linux.

That's how installation would work in a perfect world. Next week, in part III, I describe how the installation went for me. For example, I found the progress meter unreliable. If it appears that installation has stalled, it hasn't: somewhere between 10% and 50%, nothing may appear to happen for as long as a half-hour. But eventually, installation is completed.
