What is the purpose
of thick surface in CATIA V5?
The purpose of a
Thick Surface is to model a solid to represent a constant thickness of material
from a given contour. This can be used to model sheet-metal, plastic, or even a
machined part that needs to mate with a defined surface.
Do we have layer
concept in CATIA V5 like what we have in unigraphics and Pro-e?
Yes, however, the
Layers have to be created before they can be applied to the geometry. Do not
expect filters to function as they did in Catia V4. You can write a script to
sort geometry into geometric sets based on layer attribute.
What is a UUID, and
how does it affect my Catia work?
After 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.
Why can't I snap a
DMU section to a plane in V5R12sp3?
This is a Catia
regression. Create a small extruded surface and use the plane as the support.
You will then be able to use this surface as your Geometrical Target.
My Assembly will not
load or functions update.
Full Memory issue and
V5 Parm Synch issue. Load and Update a few of the larger Products individually,
and then the Top level Product. Create a Top level Parm and fx to drive the
lower level parameters via KWA Parm Explorer.
How does a Power Copy
work, and how do I create them?
A Power Copy allows
you to create a feature, imbed rules and dependencies and then copy all of this
information into a part as a single unit. For UG users, this is a 'Wave' and
for V4 Users, this is similar to a 'Ditto'. There are a few rules to live by
such as 1) Never reference H or V in sketches 2) Isolate indexing planes before
using them to support a sketch 3) Provide isolated geometries that can lock the
degrees of freedom down when copied into a part file 4) design the PC from the
Users perspective (to fit their design process) 5) Emulate Best Practices and
Decision Criteria with Rules and Checks 6) Chat with CatiaV5Dr on AOL AIM for
additional Help.
How do you switch
sketches on a part design?

First, check to see
if you have the proper license checked out. Now, make sure that the Parts
and/or Products are in Design Mode. This can be done Globally by unchecking the
Work in Cache Mode option or by switching the desired data to Design Mode via
the Right Click Contextual Menu.

I am unable to read V4 Data that contains E3D
Logical lines.
Deselect the radio
button in Tools+Options+Compatibility+V4 Data Reading that says 'Open In Light
Mode'. E3D has strong links to the Drafting views in V4 that require a 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.
Why do I lose CATDrawing links to Imported
CATParts?
Non-Catia 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.

Copy/Paste the lines into a sketch plane. From there, treat the 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.

What is the difference in Knowledge Management
and Knowledge Engineering?
Knowledge 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.

What are the Best Practices for Power Copies?
Creating 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

I am working on a
large tool,and need other designers to complete project on time. How do I work
1 tool with 3 designers? Merging seems to create more problems. Possiblly a PPR
Hub, or does collaborative design work this way?
Your best bet is to
sub-divide the work in the old fashioned way. Dassault has not provided a
working collaboration toolset that I am aware of that allows multiple designers
to work on different pieces of the Product structure. If you discover a way,
share it with us all.
1. I
have generated a fitting simulation video, but I need to reverse it. Manually
re-sequencing all of the tracks will take me about 3 hours to reverse it so it
assembles instead of dis-assembles. What video software do you use to edit
these videos? I am hoping it may have a reversal feature.

Try Photoshop Premiere, or another

available any more). Those are the only two software packages that I remember
having the inverse play/record function. I can run your file through DV Editor
if you would like to ftp it to me.

2. What is Fitting Simulation?
As the name implies, a user can create a
step by step video sequence using the Compass that describes how components can
be assembled or disassembled while analyzing Clash and Clearance. The resultant
simulation can also be used to generate an AVI file. If there is interest, I
can record a demonstration and post it on my Web site. The general concept is
to create a Shuttle to use as a container for parts that travel as a unit, and
record key frames in the form of Tracks as you move them relative to each
other. This is different than Kinematics because no Joints are required.
