I believe that using PS to present 2D details at a larger scale is a gross
mis-use of the feature. But, if you desire to do so, go to PS available
mode (TILEMODE 0) to set viewport status only, set TILEMODE to ONE to
actually draw the plans sections and details.  Toggling the TILEMODE at
the start of the editting session and back and the end of the session
eleminates the problems you have encountered.
The intent of PS/MS was to show different views of a 3D model, top, front,
side, etc. and to annotate such.  I challenge you to do that WITHOUT
PS/MS.
>I find it surprising that USTN could not make a simple angular dimension.
Usta uses what it calls UOR (Units Of Resolution) sort of like
connect-the-dots. Elements can only start and stop on a dot (UOR).  There
is a maximum number of these dots available (called the drawing plane), so
the finer tou set your UOR the smaller area you have available to use.  A
courser setting for UOR gives a larger drawing plane but drastically
reduces accuracy.
MY PET TEST:
Active Angle = 35
UOR   -  Master Units = 1 ; Sub Units = 12 ; Postional Units = 1000
This translates to 1/1000 of an inch accuracy, total UOR = 12000
Angular display setting of Deg/Min/Sec.
Using ANY Rel. of Usta (incl 95), and using ANY method of placing lines
(incl. ACCUDRAW) place a line 3'-3 5/16" long, from XY=0,0 at 35deg.  Then
place another with AA=0, from XY=0,0.
Then using the DIMENSION ANGLE BETWEEN LINES Tool, dimension the angle
between the two lines.  The resulting dimension changes, depending on
where the lines are selected, and can be off as much as 20-30 sec.  Usta
is INCAPABLE of providing a dimension of 35deg00min00sec. 
Sorry for the length,
Randy

If that is ALL you are using PS for, yuo have missed the point.  PS makes
it possible to show different views of a 3D model on the same drawing.
It can also be used, in conjunction with XREF,to show enlarged areas on
different drawings (e.g. one large plant map model, XREF'ed into several
DWG's, each with a viewport zoomed into a different part of the plant. 
Edit one model, 10 DWG's are changed)

Depending on your TRADE the TRICKS will be different, but, it is usually
'better' to build and edit model with TILEMODE set to 1 and use TILEMODE
set to 0 for setting up viewports and plotting.

Then you lose associativity with the model, updates to the model are not
reflected in your view. Sounds like double editting to me, with twice the

I'm having the same problem with my SummaIII in Acad R13 for Win NT

Hi Dave,
When you say fully justify text, do you mean the text is aligned both
left and 
right, and the spaces between characters increases proportionaly?  If so
I don't
believe it is possible in autocad, because acad dosn't have proportional

Subject: File Locking not working?
From: apt@cix.co.uk (Paul Taylor)
Date: 1 Jan 1997 11:57:24 GMT
We have recently come across an apparent problem whereby one user opening 
a drawing does not get a message to say that the drawing is already in use 
by another user. File locking *is* switched ON on both machines. It only 
seems to happen on one or two particular machines.
These PC's are running R13c4 under NT3.51.
I think I've seen messages about this in the group before, but I think 
that, like others, I believed that the poster hadn't really got file 
locking switched on! Now I have seen it myself, I wonder if it's a problem 
with Autocad.

Subject: Microstation and the MISCONCEPTION of inaccuracy
From: Jerry Walter
Date: Wed, 01 Jan 1997 07:06:46 -0500
TWIMC
    A interesting allegation has been made on this newsgroup (i.e. Not
comp.cad.microstation) that Microstation does not accurately measure,
place, or dimension angles. The allegation is that Microstation uses
a routine the same as a video screen uses to draw, i.e. pixels. The 
claim is if the graphics falls off that pixel, you loose your accuracy.
Let me explain what is really happening here.
    Microstation uses a integer based design plane, I will not dispute
that. What is missing in this allegation, is that Microstation also
uses a concept called "Working Units". These working units defines
the accuracy of the information in the design file.
    An example is in order here. If the working units are set to
	Subunits  = 12
        Pos units = 8000
then the accuracy of the file is 1/(12*8000) or 1/96,000 of a unit
(be it feet, meters, cows, etc.). To dimension, draw, or measure a
angle to the nearest second, you only need a accuracy of 1/3600 (60*60),
therefore you have thirty times the accuracy you need. If you require
more accuracy, then you up the working units. For 1/10,000,000 accuracy
(i.e. 0.00000001) then set the working units accordingly. A seasoned
Microstation user should be able to grasp this concept.
   This anology is the same as a computer works. On a computer we deal
ONLY in 0 and 1. Binary and Hexadecimal numbering is in INTEGER units.
The FPU on your computer and other software routines do the calculation
of the Floating Point number for you. If Microstation was as been
accused, then Microstation uses would not need a Floating Point Unit or
Math Coprocessor on their computer. This is not the case. 
    I DO NOT post this here to convince anyone that Microstation is
better than ACAD. The purpose is to educate a group of people that
might of been told half of the story.
P.S. Maybe the person who made this accusation, would monitor the
     comp.cad.microstation newsgroup also, they would realize that
     their accustations only concern them. I do not see this problem
     on that newsgroup.
Sincerely;
Jerry Walter

Mike,
There are a couple solutions available.
First, I think if you get the R13C4a patch it may fix the problem.
Second, edit the AutoCAD icon in Program Manager.  In the command line
box add a startup drawing name at the end.  Something like the
following,
C:\R13\WIN\ACAD.EXE DRAWING1
Now, when you double click on the icon, AutoCAD loads and titles the
new drawing, "DRAWING1".  This should allow you to use of the most
recently used file list.  You can put anything in place of "DRAWING1".
I think this is what I did at work as a work around.  I may be a
little off, but it should at least point you in the right direction.
Good Luck,
Brian Cranston

It's interesting you use 8000 as a positional unit setting. Out-of-the-box
Msta sets it to 1000. Most people don't have a clue this setting controls
accuracy and don't reset it. The result is thousands of files with a
setting that promotes inaccuracy. Thousands of drawings, cells, and seed
files that must be modified and scaled to a finer resolution.
>> A seasoned Microstation user should be able to grasp this concept.<<
The concept is easily grasped. The question is, why would a $3000 CAD
program lead its users into a built-in INACCURACY? 
>>    I DO NOT post this here to convince anyone that Microstation is
better than ACAD. The purpose is to educate a group of people that

Your half of the story left out the fact that many 3rd party programs
don't understand this built-in flaw either.  Several high-dollar programs
we have reviewed recently, use MU-SU-PU settings of 1-10-100 or 1-12-100
making angular dimensioning impossible.
A quick survey of users at the local Msta Users group showed that most
drop status and edit the error out of the dimension.
>>Maybe the person who made this accusation, would monitor the
comp.cad.microstation newsgroup also, they would realize that

I brought this problem to that newsgroup several weeks ago, hoping to get
some trick or help or something from the Bentley guys (Angular Dimen???).
The result was very disappointing.  Long tiraids on the advantages of
MU-SU-PU ?? and people explaining the connect-the-dot concept, but no REAL
help with existing client stds.
Everyone, incuding you and the Bentley Bros., want to explain away the
problem without admitting it exists. Until a sensible solution is offered
to REPAIR existing files and cells, I continue to bring it up every time
someone on the ACAD N/Gs tells someone to use Microstation.

Subject: Re: FOR SALE Autocad R13C4 and Mech Desktop
From: "Tony Tanzillo"
Date: 2 Jan 1997 01:23:32 GMT
The reason they're doing this is because many people were
able to get R13 at a very low price by purchasing a used
license of an earlier release, and taking advantage of the 
low price to upgrade to R13 from *any* previous release.
Hence, all AutoCAD licenses became an extremely valueable 
commodity, and were in greater demand than the new product.
It got to the point where some were actually making a good
living just purchasing licenses, upgrading them to R13, 
and reselling them for significantly less than what AutoCAD
dealers were getting for new product.
Unfortunately, many people feel that most AutoCAD dealers 
have outlived their usefulness, are incompetent, and of 
little help in solving their problems. 
Most dealers want to sell their customers support services
at a premium, but the sad fact is that most of the 'support' 
services that customers require is a manifestation of the
all of the defects that Autodesk has chosen to leave in the 
product, to save money.

Subject: Re: Handling directory names in AutoLISP
From: "Tony Tanzillo"
Date: 2 Jan 1997 02:52:18 GMT
There's no way to select a directory with AutoCAD proper,
and there's no way to determine if a directory exists without
creating a file in it (but AutoLISP doesn't allow you to
delete the file afterwards).
If you're talking R13 for Windows, then you would probably
want to pick up a copy of Maximizing AutoCAD R13. Included
wih it, is the Maximizing AutoCAD Windows Runtime Extension
which adds AutoLISP functions that will let you access the
the "Browse For Folder" dialog box (the same one that you 
use when you choose "Browse..." button on the Windows95/NT4 
Find: dialog box to select the folder to start searching in).
MAWin.ARX also has a (FileExists) function that allows you
to determine if a directory exists.

Subject: Summa Tablet Win 95 & R12
From: Miller
Date: Wed, 01 Jan 1997 21:28:39 -0600
I recently moved to Windows '95.  I downloaded the updated
program drivers for Summasoft 2.1.  I set up the mouse as Summagraphics
Tablet Proxy Mouse
Driver.  It works fine in all programs as a mouse.  In AutoCAD, I tried
to set it up the same way I had it in Win 3.1, with the Wintab mole
mode.  
	I read in the readme that their program for mole mode requires AutoCAD
R13.  Is there anything that will let me run it all for R12????
        In short I have AutoCAD R12, Win 95 (32 bit FAT), Plenty of hard
disk
space, 24 Mb RAM.
                                                Thanks for the help,
                                                David Miller
                                                quacken@csinet.net
P.S. I did try to ask SummaGraphics, and found that they merged with
Calcomp, so Emailed CalComp.  No Response!

I missed this bit of magic on my first pass thru your note. And basically
it is not true.
Try this:
   Using any version of Msta
   MU-SU-PU = 1-12-1000 (1/12000 is a lot finer than 1/3600)
   Active Angle = 35
   Dimension read out in Deg-Min-Sec
   Using ANY method for placing lines; key-in,  ACCUDRAW (snicker)
   Place a line 3 -3 5/15  long, from XY = 0,0
   Repeat with Active Angle = 0
   Using the Dimension Between Lines Tool, dimension the angle between the
lines
   Dimension them several times selecting the lines in different places
