It was extra work, but I exported my PCB file as PADS ASCII (Not Protel
ASCII, this didn't fix the problem), then imported it back in. I received a
message that 4 entities could not be converted. This must have REALLY
worked, because the autorouter has run fine since then.
It seems that a majority of you are doing some very dense, high-speed
layouts with 4-6 layers being quite a common occurrence. I'm just wondering
how much you typically route by hand, and how much you let the auto-router
whack away at.
I usually find that if Protel has got into this sort of routine, then it's
time to re-boot the PC (often needing power-cycling, just to make sure).
The same applies with Windows 2000, although it's not needed nearly as often
as with 95!

The Protel ASCII database is self-documenting (which is why it can be a
*huge* file), but it can be very handy for dealing with obscure problems.
All Protel users should be aware that it is possible to directly edit the
i had the same problem with Win95 some time ago. Protel did not liked the
Microsoft fax printer driver (Exchange) that time. After deinstalling the
fax driver protel printed ok.
Best way is to deinstall all your printer drivers and reinstall them one by
one, checking which of them is the

I am a circuit/system designer who is is self-taught on PCB design. I
design my own pcb's because I design portable electronics and the
flexibility of placing the components at the time I'm designing the
electronic package, etc. gives me some incredibly efficient packaging
results. I only
Rooms is a shining light among Protel's features. I lament Altium's dearth
of information about its workings, which no doubt leaves many Protel users
unaware of its capability. I recall that the few posts I've seen on the
subject were positive. Clearly, Mr Lomax appreciates Rooms, and I

The basic procedure is to select
components in Schematic, then use the Tool pulldown to select the same PCB

Rooms and assign the appropriate Classes to them.
A very good website that deals with high speed design is
www.signalintegrity.com. It is
hosted by Dr Howard Johnston and has articles on specific aspects of PCB design
terminations, bypassing, planes, routing impedance etc.
This email is to inform you of the release of a new version of the
Protel/AutoCAD 3D modeler.
New features include:
Support for remote operation - ie uses an AutoCAD licence across the
User definable outlines for auto created 3D parts
Normally I only route the boards by hand (4 6 layers) , my expierence with
autorouting utillities (not only Protel) is that you still want to change
tracks which you don't like so you will wind up re routing the whole board
The only thing i sometimes use the autorouter for is
