does CATIA stand for?

is a UUID, and how does it affect my Catia work?
researching the web for a generic answer, this is what I found: What is a UUID?
UUID stands for a Universal Unique IDentifier. These are 128 bit numbers
assigned to any object within a DCE cell which is guaranteed to be unique. The
mechanism used to guarantee that UUIDs are Unique is through combinations of
hardware addresses, time stamps and random seeds. There is a reference in the
UUID to the hardware address of the first network card on the host which
generated the UUID - this reference is intended to ensure the UUID will be
unique in space as the MAC address of every network card is assigned by a
single global authority and is guaranteed to be unique. (Alternate addresses
might be a problem here, but the author has not tested creating a UUID on a
machine with an alternate address set) The next component is a timestamp which,
as DCE always moves clocks forward, will be unique in time.Just in case some
part of the above goes wrong, there is a random component placed into the UUID
as a catch-all for uniqueness.The timestamp component though is one of the
reasons why DCE does not react well to clocks going backwards.A UUID may be
generated using the uuidgen command, the following is an example of a generated
UUID:- 58f202ac-22cf-11d1-b12d-002035b29092 This has come from a machine with
the hardware address shown in the output of the command below:- lscfg -vl ent0
DEVICE LOCATION DESCRIPTION ent0 01-01 IBM ISA Ethernet Adapter Network
Address.............002035B29092 From this it may be observed that the Network
address of the ethernet adapter matches the last portion of the uuid. Dassault
has made their applications permanently identified with a UUID by creating
their Interface Definition Language file with the uuidgen command, giving it
the "-i" option. What this means to us is that unless all files
originate from a single point seed file (thus always having the same UUID),
Component Replace and Drawing replace links will always fail.

complete load of the .model file to be viewed. I have not verified it, but
suspect that the Tubing Module in V4 has the same issue when read into V5 due
to it's similar architecture.
do I lose CATDrawing links to Imported CATParts?
Data Migration - When dealing with Cad Data that did not originate in Catia,
and basing CATDrawings on it, many issues will arise. The following workflow
will reduce the number of issues due to STEP and IGES Import methods into V5.
The root of the problem that is experienced while linking CATDrawings to
CATProducts and CATParts of new versions of files is due to an encryption
routine Windows that CATIA utilizes to create a unique identifier for each and
every new CATPart and CATProduct that is created. This encryption routine
creates and embeds an Object called a UUID which stands for Universal Unique
IDentifier. These are 128 bit numbers assigned to any object within a DCE cell
which is guaranteed to be unique. The mechanism used to guarantee that UUIDs
are Unique is through combinations of hardware addresses, time stamps and
random seeds. What that means to you and me is that the File Name that we see
when we save the file or reference it to create a CATProduct or CATDrawing is
NOT the ID that is being referenced by CATIA, and can therefore not simply be
replaced with another file of the same name. Assuming that the Cad data is not
originating in V5, the process for revising a CATPart (non-native) while
maintaining links to CATDrawings is this: 1) Non-V5 Modeling------>2)
STEP/IGES Export/Import------>3) New CATPart with Original UUID------>4)
CATDrawing------>5) Non-V5 Modeling------>6) STEP/IGES
Export/Import------>7) New CATPart with New UUID------>8) Copy/Paste from
New CATPart with New UUID to Existing CATPart with Original UUID------>9)
Open CATDrawing to verify link Basically, the concept is to establish the
relationship from the CATDrawing Child file to it's Parent CATPart or CATProduct
and maintain this relationship by changing the contents of the CATPart or
CATProduct but re-use the original file so that it's UUID remains intact.

sketch as a normal sketch and use Pad/Pocket, scaling or whatever to make it
fit your needs. There is a shockwave viewlet on my website, if you would like
to see this demonstrated.

can describe the specific case.

are V4 Surf2 and V5 Surfacing similar?
is a very broad subject,any surfacing that you were
capable of doing in V4 can be done in V5. Most of the command inputs are the
same, only the Interface and some naming has changed. V5 has capabilities that
V4 never had, but it requires an in-depth study of the tool set.

can create the MID CRV, for a set of generating curves. Also What is TANG INT ,
in SURF2+CRV CRV+TANG INT.
Mid Curve is a curve that is used to control the behavior and shape of a
surface, and is located between and somewhat parallel to the Boundary Curves,
and also are in contact and somewhat perpendicular to the Generating Curves. A
key relationship to be aware of is that the Mid Curves must be in contact with
the generating curves, and that the Spine must be perpendicular to each of the
Generating Curve support planes. The Tangent Intercept curve represents where
the focus of the conic sections of a surface lie. If you extrapolate the
surfaces that you are trying to join until they intersect and create a
Curve1+Intersect curve, you have created a Tangent Intercept. Once you get this
concept down, you can venture into the concept of Conic Surfaces that use this
resultant curve to control the tension of the surface. In a 2d sense, the TI
Curve is the same as a Conic Focal Point. Follow this link to observe an

does the V4 to V5 Batch Migration Utility do?
V4 to V5 Batch Migration Utility does the following: -- Creates a separate
CATPart for each Set in the model. -- Creates a separate CATPart for each
Workspace in the model. -- Creates a CATProduct for each Workspace that contains
Dittos. It then instanciates the CATParts that were created from the respective
Workspaces. If there is only 1 set and/or 1 workspace, no CATProduct is
produced. -- For each solid in each workspace, a separate PartBody is created.
No geometry is placed into PartBody.1 -- Only Geometry in SHOW is migrated. If
a Solid has Parent Geometry, that is brought along as well. All of this
information can be found in the on line documentation. Jim Strawn Cessna

is the difference in Knowledge Management and Knowledge Engineering?
Management is the discipline of extracting, storing and balancing Intellectual
Property in a parseable database. The act of leveraging this IP with
Applications and Processes is Knowledge Engineering. In the simplest form, the
use of a standards document by a designer is Knowledge Engineering. I reserve
the term 'Knowledge Engineering' for the act of developing Software
Applications leveraging Database Knowledge in order to compress design cycles
by providing new efficiencies.

are the Best Practices for Power Copies?
a PowerCopy As far as possible, minimize the number of elements making up the
PowerCopy. When defining PowerCopies including sketches, use profiles
constrained with respect to edges or faces rather than to planes. Additionally,
set the option Create geometrical constraints off before sketching. Generally
speaking, it is always preferable to use profiles both rigid and mobile. It is
preferable to constrain elements with respect to external references such as
faces, edges, reference or explicit planes. It is preferable not to use
projections nor intersections in your sketch if you want to use your sketch in
a PowerCopy. Avoid constraints defined with respect to reference planes. Before
creating your PowerCopies, make sure that your sketch is not over-constrained.
Make sure that your sketch is iso-constrained (green color). You can use
non-iso-constrained sketches, but it will be more difficult to understand and
control the result after instantiation. Create sketches on an axis system, in
order to better control the Sketch position. Avoid access to sub-elements.
Formulas are automatically included if you select all the parameters. For
complex design, integrate knowledge rules. Managing inputs: Always rename your
inputs to help the end user understand what he needs to select. A formula is
automatically included in a Power Copy definition when all its parameters are
included. Otherwise, i.e. if at least one parameter is not selected as part of
the Power Copy, select the formula to make it part of the definition. If you do
so, all the formula parameters that have not been explicitly selected, are
considered as inputs of the Power Copy. Note that when including parameters
sets containing hidden parameters in a PowerCopy, the hidden parameters are
automatically instantiated when instantiating the PowerCopy. Preview: In a Part
document, create only on
