After 13 years of Parametric 3D, my opinion...

A lot of what SolidWorks Corp. does, doesn't make much sense because
it's a company that is almost totally driven by it's marketing
department. If one needs to feel the comfort of being with the market
leader at the cost of not having great technology at your fingertips
then SolidWorks is the product to stay with.

VX is a company that barely understands marketing. :>) Maybe one
day....

I believe Impact Soft is based on ACIS.

Catia is not ACIS based although Dassault does own Spatial.

Only a matter of time before CATIA and SolidWorks share the ACIS
kernel. More SolidEdge seats sold will help that and UGS is certainly
moving in the right direction with SolidEdge.

I do like a lot of CATIA's UI. VX would greatly benefit from elements
of it's UI being more like CATIA's. I wouldn't hold your breath.
The UI does not seem to be VX's real priority. I think you will see
better tools for progressive die design and I guess for mold design
(electrodes) and certainly CAM improvements way before you see major UI
redesign in VX. I belive you will see slow but steady progress in VX's
UI but nothing really radical.

I wish we could get more of the people using VX, like Newport Tool and
Die and VX users in the mid-west discussing VX and helping each other.
A lot of VX's very advanced surfacing power needs help being documented
and users could go a long way in helping each other out.

How about a independant VX advanced surfacing book / video being done
by someone ?

I'd be a lot more interested in both of the above than UI improvements
in VX.

No new buzzwords, eh?

 

Probably explains why they have so many seats, right?

 

How so?
YOU don't actually use either. Or ANY at all .....

 

No clues here, eh?

You don't even know what a kernel is or does,
much less anything else.

IF UG uses ParaSolid but ParaSolid cannot ....
LMAO !!!

 

It might make more sense for Catia to port to ParaSolid.

 

IOW Supplying what their customers want & need in addition
to features needed in possible new markets.

Rather than clueless buzzwords & vaporware ....

 

Not that you've ever used it or probably even seen it.

 

Would that be the Catia V4 or Catia V5?

Or are you "thinking" of the import/export stuff?

<Snicker>

So it's not even good enough for Catia to use?

 

Where's that idiot that was claiming that the UI was
all-important and about all that mattered (if the buttons
were the right color)?
Have you met him yet?

He'd like you <G>.

 

Whoa Jon...you quote,"Parasolid is devoid of many of the surfacing
tools that a developer so
badly needs to develop a truly seamless, unified, hybrid modeler."

I have personally used Unigraphics to generate code for 6-axis milling
of turbine blades with not a single glitch.

The proof is is the efficiency numbers kicked out by the turbine
actually making power, not a bench-top simulation.

Parasolid is the most widely used and accepted for a reason, it
withstands the demands.

Whoa Jon...you quote,"Parasolid is devoid of many of the surfacing

I think there are differences in the actual "kernal" functions; what's
native to the kernel, what's fed to it from higher level functions.... at
any rate much in the way of definition / creation isn't done at the kernel
level and we, on the outside, don't really know where to place praise or
blame. I'm not a big fan of ACIS, but I think Autodesk gave the kernel a
bad name; it's largest customer, a ho-hum implementation equals a bad rap?
Also think Parasolid's strength may be that it doesn't try be a "do-all
plug-in" and developers are not limited by it as ACIS based developers are.
(Pure conjecture on my part....)

 

Jon,

http://www.smcsolutions.com/ixpdf/ix_faq.pdf See page 2 item 5.
ImpactXoft uses Catia V5 as its kernel.

You are thinking of the old version of ImpactXoft that used a non-Catia
Kernel.

 

Unigrahpics is an extremely capable system. It's also the only kind of
CAD/CAM system that I think can deal with the kind of real world
modeling tasks that many of us face everyday. IOW, Unigraphics is a
hybrid modeler. So.... what's the problem ? The problem is that
Unigrahpics is not based solely on the Parasolid kernel that is
available to developers. The Parasolid kernel that is sold to
developers does not contain many of the surfacing routines that
Unigrahpics uses. Lets be realistic. UGS is not stupid... they aren't
going to give away the house.

Your best bet is to talk to developers who use ACIS and find out why
they don't choose Parasolid. The answer you will get is that ACIS gives
them the surfacing tool kit that Parasolid does not. Why not E-mail Tim
Olson of Concepts Unlimited and ask Tim (who is the author of Vellum
Solids and Concepts) why he didn't choose Parasolid.

What's Parasolid does contain is excellent. It's what Parasolid doesn't
contain that is the problem.

He's wrong yet again? LOL ....

BTW, Is ImpactXoft V5 perhaps confused with Catia V5?
Looked like it worked with Catia V4, not Catia V5 (from
other data some time back). Sometimes hard to tell how old
things are on the Web ... but it was from their own Web Site IIRC.

Actually, it does not seen to have a kernel of it's own .... it's
an add-on API program just for Catia V4 from the looks of it
and, per your link, works with nothing else.

So he was again wrong it seems.

 

Umm ... 6 axes? Milling? From UG or *ANY* system (directly)?
There are 6 degrees of freedom and the angular rotation of the
spindle uses up one of them ..... that's not usually a positioning
axis ... hence 5 axes is about the max ??

Much of that is the result of the design and the CFD work
that went into it.

BTW, Clue for jb: Those turbine blades are usually non-developable
surfaces ..... IF it's the blade surface that's being machined.
Most are cast and those airfoil surfaces is not later machined
(except to add a few features, perhaps, such as cooling holes ....
which are made with Lasers (used to be EDM).

(Applies to aerospace jet engines.)

 

Your right I was thinking of the old version.

"IX Design V5 is built on the CATIA V5 kernel called CAAV5. It is the
only design solution that is completely and natively interoperable with
CATIA V5."


Anyone else licensing the CATIA V5 kernel that you know of ?

Sure be nice to see a few of the companies using Parasolid dump it and
move to a kernel that gives them the surfacing capabilities that CATIA
has. I wonder if anything gets stripped out ?

A very helpful post... thanks for the heads up.

jon

 

You REALLY are a droolling idiot, right?
They are an addon.

You already have to have CATIA.

Yep. Drooler for sure.
Thinking of UG or SolidWorks?

Ever actually SEEN CATIA?

A huge help to you there at Kinkos is it?

Like your berain out your ears if you know what
any of this was about?

Still no clues.

 

You don't have clue #1, do you?

You don't have clue #2, do you?
