Subject: [Acis-alliance] STEP 203
Message-ID: <[e-mail]>

hi
as the built in step converter in ACIS wont give me the relationship between
the faces represented in STEP and those in ACIS
i am trying to write my own converter from ACIS to STEP which is much easier
that the other way round.
But, obviously I am not able to find out where my mistake is in the STEP
file.
I have a conical hole in rectangular part.
But, the step file i generated shows cylindrical hole and non manifold
geometry
i have attached the file along.
can anyone tell me what wrong and how do i find out in the future as what's
wrong?

With Regards

Subject: [Acis-alliance] access violation error in api_hook_annotations()
Message-ID: <[e-mail]>

Hello

I keep getting access violations in api_hook_annotations() and have not been
able to get to the bottom of the problem and would like to know if anybody
else has had similar problems and have found what the cause is.

Basically on recalling a model in a new session, the first call to
api_hook_annotations() fails with (result).quant == 1015 which is an access
violation. This gets handled correctly and the failure does not effect the
model in any way. Recalling the model in the same session doesn't suffer the
same problem, it only happens on the first ever call to
api_hook_annotations()  in any modelling session.

To me this sounds like an initialisation problem but I can't see any problem
in our code.

I could ignore this problem as it seems benign but I'm concerned that it is
a symptom of something else that could be more serious so I'd like to solve
it and would really appreciate any comments, suggestions or ideas.

Thanks

Regards
Christian

Here is how we turn annotations on

       {
              // Get acis to create annotations
       outcome result = api_set_int_option("annotations", TRUE);
       UTC_ASSERT(result.ok());

       result = api_set_int_option("unhook_annotations", FALSE);
       UTC_ASSERT(result.ok());

              // hook annotations required for addressing
       result = api_hook_annotations();
       UTC_ASSERT(result.ok());

       m_annotationsAreOn = true;
       }


And here is how we turn them off and reset.

       {
       if (m_annotationsAreOn)
        {
               // unhook annotations required for addressing
        outcome result = api_unhook_annotations();
        UTC_ASSERT(result.ok());

               // Clear annotations required for addressing
        result = api_clear_annotations();
        UTC_ASSERT(result.ok());

        result = api_set_int_option("unhook_annotations", TRUE);
        UTC_ASSERT(result.ok());

               // and switch the option off
        result = api_set_int_option("annotations", FALSE);
        UTC_ASSERT(result.ok());
        }

       m_annotationsAreOn = false;
       }

Subject: [Acis-alliance] Error while evaluating distance from the point to
	the surface 
Message-ID: <[e-mail]>

Hi Friends,
I am getting the following Error while evaluating distance from the point to the surface using  " api_entity_point_distance() " function.
can anybody help me why this error is coming ?. Is the Surface is not proper or any other reason?. I checked the surface continuity , it looks good and maximum (C0) distance is 0.035mm.

Error details:
**********************************************************************

Folks,

Can we develop ACIS based applications on Windows-Cygwin with gcc as
opposed to VC++?

Thanks,

I will be out of the office starting  10/12/2004 and will not return until
10/27/2004.

I will respond to your message when I return (perhaps sooner if the
ethernet gods are kind to me).  Please contact my manager, Linda Lokay, at

I have worked in cygwin, but you still have to use cl instead of gcc due
to differing ABI's.  I think this may be less of an issue with gcc 3,
but I have not tried it.  Also be very careful in building your makefile
to use the same flags that Spatial does or cl can actually give you
incompatible binaries!

Hi,

At this time I am having the exact same problem and it seems It seems
some of the old functionality of gihusk will have to be hand
implemented as the event handling from hoops is quite different. I
just wanted to know if in the mean time you were able advance and, if
so, if could provide me with some guidelines regarding the process.

Message-ID: <[e-mail]>

Hi Pedro,
I'm sorry but, we have postponed the porting to HOOPS.
Instead we have requested the sources of the gl/gi husk from spatial.
So we are able to still use it with ACIS 13 now.

I would suggest to contact spatial support in order to request the sources
too.

If you go the other way and use HOOPS, 
please keep me uptodate with your progress, 
since we still plan to use it later too.

Greetings
Markus
