Solid Works Kernel

Hi,

I heard from many friends working with Works that UGS is thinking about
canceling the contract with DS. What will happen with Works without the
parasolid kernel. Does somebody know if there are migration strategies for
our files?

regards

buko

 

Can you tell us more about where you heard this and what exactly was
said?

 

The best thing that could ever happen to SolidWorks development into a
true seamless, unified, hybrid modeler is dumping Parasolid. I have
said exactly this in this newsgroup for a long time.

That's because you are a total idiot without a clue.
Not one.
Been popping kernels much lately?


BTW, UG uses the ParaSolid kernel.

 

There are kernels (topology engines) and there's the Applications
Software ... which SW in this case provides (or the user may have
third party software or have written some themselves) that works
with what SW has provided already (or any other vendor).

SW Could probably switch kernels with a bit of effort & cost ...
but it should then look almost exactly the same to the user. Except
for all the new added bugs.

Poor jb's totally clueless. As always.
After all, it's all just buzzwords ....

 

Just who are these friends and where do they get their information?
We're all engineering professionals, right? Shouldn't we be checking
the validity of our sources?

I doubt there is much truth to the rumor as you state it. Parasolid is
a product on the open market. It is openly advertised by UGS for
licensing for use in CAD systems.

UGS is not going to unilaterally "cancel" its license to DS and just
walk away from one of its best customer's money.

 

Hey, that was my question. Given that buko has never posted before, has
not responded and has a hotmail account this is probably some lurking
marketeer from the competition trying to spread FUD.

And what the heck, AutoDesk switched kernels in midstream with no
change in performance. So why couldn't SW? And then there are all the
really good hybrid modelers out there running multiple kernals
successfully (TIC).

 

Well, there's always that.

Probably not.
They'd have to know *something* at least, right?

AutoCad's capabilities may be limited.

Ummmmmm ... I don't really think so.
Doing translations of data between them perhaps.
But using multiple ones as their core topology data structure?

That would be about like every time you open or file a part
you use a SW part on disk & an AutoCad part.

In addition, even with using translation, only data structures
that are 100% common between them can be bidirectionally
translated.

 

....... AutoDesk switched kernels in midstream

Shape Manager?
They bought ACIS 7 code and changed the name.

Just curious:
Which are the "really good" ones?

 

It may very well be that it's FUD but it's only a matter of time before
ACIS does become the main modeling kernel for SolidWorks. When it does
occur it will be the best thing to happen to SolidWorks since the
SolidWorks database was rewritten to support disjoint solids.

Why would AutoDesk see any change in performance as all Autodesk did
was purchase the ACIS source code and rename it Shape Manager ?

You are correct that IronCAD does run both Parasolid and ACIS and that
this approach does have some advantages.

All your clueless posts?

More of your endless lies & clueless BS?

He**, you don't even have clue #1 what a kernel does.
Just another buzzword .....

You don't even have clue 0, do you?
What was that about kernels again?

Removing capabilities almost always increases speed <G>.

You just don't have any clues.

Nope. It can only use one.

But you are a flaming idiot, right?

As has been so well noted in the past:

Hey, folks, OVER 3,000 hits so far !!!!

HTH

 

I wouldn't worry about it. I have been told by several SolidWorks
Mangers on different occaisions, in different parts of the U.S. that
SolidWorks has a working up to date version running on ACIS. So if
Parasolid did dump SolidWorks (which would be a shock if it did)
SolidWorks is ready.

Ken M.

 

I do believe what you wrote above is true with the exception of it
being a shock. It would be no shock and probably would have happened by
now if ACIS was as robust as Parasolid for solid modeling operations.
My understanding is that ACIS is much closer than it has ever been in
this area.

If PTC, VX and think can start cranking up sales at SolidWorks expense
it would help speed the process of moving to ACIS.

Because a blithering idiot said so?

Planting many kernels next spring?

 

But the poor confused idiot wrote in response to:
"Did you say that Solid Works uses ACIS routines?"

Confused idiot:

"Yes. As SolidWorks has continued to develop more and more
ACIS DLL's appear when SolidWorks gets installed."

Solid Edge was ACIS based up until version 5 at which time they switched to
Parasolid. The switch was fairly painless (open and save all files in the
new version) and resulted in a more powerful, faster and reliable modeler.

Ken

 

All true. However, lets jump forward to today:

ACIS has greatly improved.

ACIS offers surfacing functionality that is not included in the
ParaSolid kernel.

Solid Edge relatively new surfacing functionality Rapid Blue is not
part of Parasolid.

No one besides UGS has built a seamless, unified, hybrid modeler using
Parasolid.

One of the major reason companies like Cimatron, Concepts Unlimited,
Kubotech, etc. go with ACIS is because of the surface functionality
that is a part of ACIS that is not a part of Parasolid.

http://www.spatial.com/components/acis/

"ACIS features an open, object-oriented C++ architecture that enables
robust, 3D modeling capabilities. ACIS is ideal for constructing
applications with hybrid modeling features, since it integrates
wireframe, surface, and solid modeling functionality with both manifold
and non-manifold topology, and a rich set of geometric operations. With
ACIS, you get a sound base of 3D modeling functionality, plus the
flexibility to meet individual application requirements."

So it's got problems, in your opine. What else is new?

NURBS is NURBS, right?

LOL .... not a clue.

What do you think a kernel is?

Idiots with buzzwords could not.
What's ParaSolid? What's a kernel? What's NURBS? What's a surface?
A solid?
What's inside a solid? Little red & blue frogs?

You never have a clue, do you?
Not once, in all these years.

So what? It's a sales blurb, right? Where you get buzzwords from?
