    Where is the Dr.? I hope that he's found something for a good Rx
    against these nasty bugs we are seeing at GD.
    
    btw-
    
    I have xferred within Digital to San Diego to work on the GD IMS
    program. My new contact #'s are in ELF.
    
    regards,

	As Hawkeye once said, "More specificity, Frank".  IOW, Steve, could
 you detail some of the bugs?

    Let's start with IGES.                   
    
    Have you any wool? Yessir, yessir 3 bags full...
    
    I think I'm loosing it.
    
    Whatever "it" was?

	Ahh yes...IGES.  We're having many problems with IGES.  Specifically,
 we've tried to output sheet metal parts through IGES to pass along to SMP-81
 for fabrication.  What occurs is, screwy things happen to the scale of the 
 output and certain pieces of the data seem to drop into the bitbucket, i.e.
 the material thicknesses of the contours disappear, while all the radii retain
 their thickness...very strange.  This is not an SMP-81 specific problem, the
 bad data appears when we try to pull the part up in UGII also.

	Matra is aware of the problem and is working on a patch but I don't 
 know if it's out yet.  Maybe Al Lamoureux can jump in here and give us an 
 update....

	So, keep a grip, Steve, it's not just you!  8^)

    We have spent the last week trying to understand IGES and are getting
    closer. Our current goal is to get 3 d wrieforms passed to UG and
    to SMP 81 .
    
    From what we can tell so far there are a whole bunch of output
    switches that can be set to change file formats and other good
    stuff. The lack of documentation is slowing the efforts down.
    
    IGES may well work if we know how to set it up . 
    
    	thanks Charlie

    
    Charlie,
    
    We have done some intial work on understanding what the switches are
    and how it works. Bob Unnold has spent quite a bit of time with it. He
    is putting out a document that will highlight the procedures. 
    
    Also, he did some passing of files between Euclid to DECview3D. The
    findings will also be documented.

    We have succeeded in getting IGES files into SMP-81 and are
    now planning to do actual post processing on the parts and
    get them made in the Mill proto shop.
    
    We are woring on IGES importation into UG and Decview3D next.
    
    When we find all the right magic decoder setting for IGES to
    each of the tools we are interested in we will post it in the
    notes files. We expect there will be different IGES representations
    depending on the tool your are going to. An example is do you
    want a circle as a poly-line or and arc.
                                            
    thanks Charlie

    I hadn't read this note before so I wrote a new note, No. 27, to
    announce the successful fabrication of a sheet metal part from Euclid
    solids geometry, ported via IGES to SMP81 for NC postprocessing.

IT'S BEEN AWHIDE BUT EUCLID IS STILL HERE. I'M RUNNING EUCLID3 ON A ALPHA OSF
3000-300 AND IT IS FAST AND WORKING GREAT. 
EUCLID3 HAS A LOT MAJOR IMPROVEMENTS;

				CHANGING SHEET METAL MATERIALS
				STRETCHING SHEET METAL PARTS
				ADAPTIVE SURFACES (LIKE SOLIDS)
				B-REP EVALUATOR (SOLID TO SURFACE)
