	The problems appear when I want to erase or unhighlight the recently drawn 
point. Deleting or unhighlighting the point it erase the portion of my 
entities in the view where it was drawn. In other word I want to display 
and erase something in such a way that it doesn't affect the view below the 
figure. It should be similar to a mouse cursor: when the cursor moves 
toward the "thing" under the cursor figure doesn't change and there are not 
redrawn. In my opinion there are some binary raster operations that handle 
this but I'm not sure. I tried to set some drawing modes with:
	ActualCDC()->get_view_context().set_drawing_mode(XOR_MODE);
but it doesn't work.

	Please I'm desperately need somebody's help to handle the problem. If I 
wasn't clear enough please drop me an email in particular and I'll provide 
some additional explanations

Subject: [Acis-alliance] creating ACIS object dynamically
Message-ID: <[e-mail]>

Hi,
I am a beginner to ACIS with a limited knowledge of VC-MFC.
 
I have a problem with creating any ACIS object dynamically.
 
There is a class provided for ACIS memory management "ACIS_OBJECT", but I hardly could make use of it to use 'new' and 'delete' overloaded operators to create and destroy objects dynamically.
 
I would appreciate your help in this.
 
I am using ACIS 7.0+VC MFC.
Thanks and regards
Manoj.

Hello everyone,
I was wondering if it was possible to use the "codes" for ACIS written
for UNIX  in Windows. If I can do that, where can I find help as to how
to convert those files ?

Message-ID: <[e-mail]>


I am trying to create a SAT file (ACIS), in order to insert my geometry 
(3D artery) into a MESH generator. Nevertheless, I can not find enough 
documentation in order to understand and create the ACIS (SAT) format.

Could you please provide me with some information? How can I find 
documentation?

Sincerely yours,

Message-ID: <[e-mail]>

ACIS is a solid modeling representation.  It includes both geometric and
topological
entities.  I do not recommend attempting to create a SAT file from scratch
-- it can
be done, but even after roughly 16 years working with it I don't like to
directly
construct one.

There are a number of ways to move forward:
0.  Find a CAD system that works natively in ACIS (e.g. Autodesk Mechanical
Desktop).  Build
your model there, write the SAT file, and move forward.

1.  Find a CAD system that can export to SAT format, or some other format
that your ACIS-enabled
application can read (e.g. IGES, STEP, etc).  Construct your model with the
CAD system, export
to SAT.  Example CAD systems include SolidWorks, Pro/E, Catia.  Some of the
translations from many
of these CAD systems are rather fussy, but can be made to work.

2.  Obtain a copy of ACIS and write software that directly constructs what
you want in ACIS,
via sweeps, booleans, etc.

3.  Find somebody who can do one of the above for you..

Hi,  dear friends,

I am a beginner of ACIS. I am using ACIS 7.0. I want to know exactly the meaning of data in SAT file. 
example:

3 shell $-1 -1 $-1 $-1 $-1 $4 $-1 $1 #
4 face $-1 -1 $-1 $5 $6 $3 $-1 $7 forward single #
5 face $-1 -1 $-1 $8 $9 $3 $-1 $10 reversed single #
6 loop $-1 -1 $-1 $-1 $11 $4 #
7 plane-surface $-1 -1 $-1 0 0 15 0 0 1 1 0 0 forward_v I I I I #

Can anyone kindly explain the meaning of data? Any response is appreciated.

regards
shaohui

Hello everyone. I am trying to build a simple MFC app wizard in VC++ 6.0
for ACIS R12. 
But I cannot figure out how and which wizard to use. 
Is it the 
ATL COM appwizard 
MFCApp wizard (dll)
MFCApp wizard (exe)
 
 
If anyone has a simple MFC created, I'd be happy if u can mail it to me,
if possible

Hi everybody!

    there are some holes in a plane。i want to expand the exterior loop and  minify the inner loop.how can i do this?
how can i judge which place the exterior loop is in link list?the first? the last?or other?
    i look forward to replying.
    thank you!

api_loop_external(LOOP*,logical*);
This api returns TRUE if a given loop is the outermost loop.

Subject: [Acis-alliance] Close gap between Edges
Message-ID: <001401c3b386$df51b790$[e-mail]>

Hello ACIS-Alliance,

I want to construct a loop of several edges. Adjacent edges should share
the same VERTEX. But some of of the edges have small gaps (>SPAresabs).
Does anybody have an idea how to close these gaps?
Can I use api_trim_curve(...)?
If yes, do you know how to construct the entity_with_ray, which is used
in this function?

Your help would be appreciated.

Best Regards,
Alex

The loops in ACIS are generally in no particular order.  There is, in
general, no "exterior" loop in any face.  Consider a cylindrical face, with
two circular loops, one at each "end", as per the cylindrical side of a can.
Neither loop is "outside" -- to remove either makes the face infinite.

In the case of a planar face, and for certain cases of NURBS surface, an
exterior face is possible to consider.  In such case, you have to test the
loops to determine how they bound the surface.  If you removed all the loops
from the surface, then attached one at a time and measured the surface area
of the resultant face, you would find that all but one loop produces a face
of negative area; the loop producing positive area is the "exterior" loop.

But again, please note, this is not a general test, as your question is
ill-posed for non-planar faces.  For the cylindrical case, note that
depending on the location of the loops, it is possible for either or both to
produce positive area.
