SolidWorks 2005 Surface Tangency

http://www.caddigest.com/subjects/solidworks/select/cadcamnet_proe_vs_solidw
orks.htm

"Although SolidWorks enables adjacent lofted surfaces to be tangent,
it can't assure continuous curvature (C2) between two surfaces"

Is this fixed in SolidWorks 2005 ?

No problem making faces tangent continuous in VX.

Jon:

I just can't let this one slide. Against my better judgment, I'm going
to ask you if you understand the difference between C0 ,C1, and C2
continuity.

"No problem making faces tangent continuous in VX." only accounts for
the C1 condition.

Everyone else:
Let's just quietly wait and see if he can actually give a coherent
answer.
Cliff:
Stay out of this for the moment. I want to here his answer.

I have already gotten a few e-mails asking for an explanation of what
C2 surfacing is and what the hell is it needed for. :>)


I like this simple definition:


http://www.cadserver.co.uk/common/viewer/archive/2000/Aug/10/feature3...


"Surfaces are classified in three different ways: C0, C1 and C2 according to
the degree of contin-uity (smoothness) of the surface.


A C0 surface has one or more breaks in its continuity. A break in continuity
of a surface is an abrupt change in surface direction. For example two flat
sheets of metal joined at right angles have an abrupt change in continuity
at the right angle. They form a C0 surface.


A C1 surface has one or more changes in curvature that could cause serious
problems to the cutter of a machine tool. For example, the cutter could
gouge into the metal surface when the curvature changes. You might ask what'
s the difference then between a C0 and a C1 surface. Well, a C0 surface has
no tangency at the discontinuity, whereas a C1 surface does have tangency.
For example, a C1 surface could be made by joining a flat sheet of metal to
a curved sheet of metal, such that the flat and the curve are tangential
across the joint. Gouging can still occur where the sheets join, especially
if the curvature is too much for the machine tool.


C2 surfaces are, as you have probably guessed, the bee's knees. C2 surfaces
have continuous curvature."


jon

 

Not bad. Better than I expected.

Now, can you find the C0 dicontinuities in the logic of your original
post?

 

I'm really not concerned with living up to your expectations.

I will say this latest charade of yours, where you got blown out of the
water once again, shows why I have such low expectations of you.

"The Virus" will be along any minute so you can suckle.

As explained by Joe Greco:


"C0, C1 and C2 Surface Conditions


Generally, there are three kinds of boundary
conditions in a surface model. C0 refers to surfaces
that are just touching but could potentially have a
shape corner or crease; possible manufacturing
problems can result. C1 refers to a tangent (smooth)
condition, and C2 to a consistent continuous tangent
curvature. With C2, the boundary is imperceptible to
the eye-you can't see were one surface begins and
where on ends."


jon

 

"Tangent continuous" means C1 continuity.

How does VX's ability to handle C1 continuity compete with SW's
shortcomings in handling C2 continuity?

I'm going to end this now. Go ahead and get the last word in. I'm
going to go gas myself in the garage now because I've learned you have
low expectations of me. Truly a mortal injury to my fragile psyche.

 

I forgot to add my dying words...
"No, this doesn't mean I'm taking sides with Cliff."

 

C2 means that the tangent direction and the curvature of the surfaces are
the same and like I said... VX can do this. Apparently SolidWorks still
can't.

Any reason you can't download VX and see for yourself ?

jon

 

Ok, I have to ask, why all of the bad feeling here??
I don't take sides, just curious

 

Just by you repyling to him makes you part of the VX team clique brah.

GO TEAM VX!

And keep going all the way down the road clutching yer free demo's.

OK, last time I checked this was a SolidWorks NG, people posting questions
about how to work with SolidWorks and all its inherent limitations. JON,
**** OFF with all your uniseamed inbred modelling software If VX is sooooo
gooood why the **** do you need to poach solidworks users from this NG?

VX a "uniform inbred modelling solution" date yer daughter...

Solidworks is great, I love it. I dont give a shit about VX or VD or
whatever you are pushing, I want to listen to knowedgeable solidworks users
and benefit from their knowledge, if you had at least the slighest fucking
clue you would listen quietly and develop your second rate software so it
might stand a chance of competing in the MCAD market, last i checked VX was
a dot on the horizon compared to SWX or IV.

OK, now listen up. I don't like to take sides -- especially JBs side --
but what he did here was to give us a shot at trying out something else
at no risk to us. That's not a slap in the face (well, maybe a little
slap, but a harmless one). Yeh, maybe his yammering gets on my nerves,
too, but I can't say I like the tone that the whole newsgroup is taking
about his posts. Even though I've poked him myself a time or two lately
(and enjoyed it) I think it's better just to observe the adage:
"Don't feed the trolls"

Stooping to a low level doesn't help anyone.

Hey Mark.

Did they have those machine screws ??? I never got around to checking

Mark

 

Tell him to show me results then.

Somehow I dont see anything other than bolstering

Lame attempt as well.

Bing

 

Was that long enough?
He had no clue. Not a one. As usual.

 

It was just a copied bit from someone else and missed entirely the
question about "faces tangent continuous in VX" & C1 <G>.

 

No clues from jb <G>.

 

Two things I believe in, is free speech and not sticking my head in the
sand.
I thought you had those views in the USA, too?
If replying to Jon makes me part of the VX team, so be it!
Strange thing is, a free demo, was what got me in solid works!
Free demos of Inventor and ProE convinced me, that they were not for me.

 

Uh, I thought I was exercising my right of free speech.

Well, good for you.
Only demo I ever got for a CAD system was from Dink3.

Oh, you must be talkin bout those other demo's
