Subject: [Acis-alliance] Get the "Sequence Number"
Message-ID: <Pine.A41.4.21.0507211402320.41632-100000@delos>

Dear subscribers,

There is an optional parameter written to the sat files, at the first row,
which is called "Sequence Number". It relates unambiguously to the entity
defined in that line, and is used in attribute statementes by the
"attrib" methods, for example. 

How could I get this for a sat file, if it is loaded with acis-hoops
bridge in a GUI?

There are several method to convert entities from the hoops database to
the acis database, but I found no method that returs the "Sequence
Number" for a given hoops key, or entity pointer.

Thank you in advance, 
Edilson Gr?nheidt Borges

Hello,

I am looking for a function that lets me check if a certain point lies 
on an EDGE/curve. Any clues?

Thanks,

Stefan

hi,
 
for curve there are two member-functions:
test_point(...)
test_point_tol(...) (for a given precision)

for edge there is an api:
api_edent_rel(...) which determines the relationship between an edge and an
entity (in this case Point).

best regards,
alex

The function referred below works!
and if you need any work around, there is a lot of information in the
PDF/INTR/04FN.PDF
file in your ACIS help folder...
for some reason, the PDFs tend to give more information than the online
help...

Hi,
I got the manuals somewhere (I forgot its url and name...), and they are
instaled at 
~/online/refman/generated/refman/MethodIdx.htm
directory in my computer.
There are lots of references to the 'lies' term:

test_point method in class surface
    Determines whether a point lies on this surface to the system
precision.

test_point_tol method in class sphere
    Tests whether a point lies on the surface, to user-supplied precision.

test_point_tol method in class VBL_SURF
    Tests whether a given point lies on the surface to within a given fit
tolerance. 

test_point_tol method in class straight
    Tests a point on the curve, returning the parameter value if it is
required. 

test_point_tol method in class plane
    Tests whether a point lies on the surface, to user-supplied precision. 

test_point_tol method in class cone
    Tests if a point lies on the surface to user-supplied precision. 

test_point_tol method in class torus
    Determines whether a point lies on this surface to the given
tolerance. 

test_point_tol method in class spline
    Tests whether a point lies on the surface, to user-defined tolerance. 

test_point_tol method in class ellipse
    Tests point-on-curve to given precision, returning its parameter value
as well if requested. 

test_point_tol method in class intcurve
    Tests if a point lies on the curve to a given precision. 

test_point_tol method in class surface
    Determines whether a point lies on this surface to the given
tolerance.

body_coedge method in class ATTRIB_INTCOED
    Points to the coedge linking the edge to the face if the start vertex
of this coedge lies on an edge of the face.

face method in class ATTRIB_INTCOED
    Returns the face of the body on which this coedge lies.

etc...

Are these some kind of clue? I do not undertand at full the meaning of the
word 'clue'... :-)

Subject: [Acis-alliance] How can I build one body by faces?
References: <[e-mail]>
Message-ID: <[e-mail]>

Hi,

I'm trying to build a body by using 6 faces, to produce a cube. Up to now, I
just found the functon 'api_make_solid_from_faces', which returns just six
new shells instead of one body. 
Would be glad for any help.

hi, you should use the stitch functions to do so. If you are making body 
through a series of faces, the body will be of multiple shells. 
in ACIS r13, the following words in the help document may explain what we 
should do in this situation 
"The Stitch Component (STITCH), provides a way to stitch - or sew - 
separate faces together to make a sheet or solid body that is topologically 
complete. Stitching essentially involves replacing coincident groups of 
edges or vertices in the data with a single edge or vertex.  
"
api_stitch is the main function of this module. You can look into it for 
more details.
Cheers
