Subject: [Acis-alliance] How to import CGR files
Message-ID: <[e-mail]>

Hello,
 
we are working with the latest ACIS releases for Interop and VizExchange. We
are using them for loading CATIA V5 models. However, Inerop does not to seem
to support CGR ( CATIA Graphical Representation ) files. They are sometimes
used in assemblies together with CATPART files. The CATIA5 reader skips
them. 
What is the best way to import the data from CGR files into ACIS?
 
Thanks,
Arne Schilling

Subject: [Acis-alliance] Using api_save_entity_list_with_history
Message-ID: <Pine.A41.4.21.0507121755420.27202-100000@delos>

Dear subscribers,
How could I save the Entity Recorders as a Sequency Number using
api_save_entity_list_with_history? I must retain this information when I
overwrite an existing file. With no options, it saves the entities, 
their attributes, etc, but not the Sequncy Number.
Thanks,

Hello,

  I am looking for an example of how to construct a SHEET in ACIS given
  its contours as EDGES. Thanks.

Hello,

in my code I do:

SPAposition *pPnts = ACIS_NEW SPAposition[numpoints];
//Copy Point data
result = api_make_wire(0,numpoints,pPnts, pWireBody,0);
result = api_cover_wires(pWireBody, *(surface*)0, faceList,0);

... but the faceList is empty. Do I need to pass in a surface (e.g. a 
plane) maybe? And if so how do I create one?

What's the content of your pPnts array?
Are you sure that it defines closed loop(s)?
Have your tried to check pWireBody using api_check_wire_self_iters?
What's the result of api_cover_wire?

In most cases you don't need to pass a surface.

Ok I figured it out. It was a fencing/counting problem as there are n 
points but n-1 egdes. All works now. Thanks a lot.
