continuty of a surface

[bsvk]

Hello all,

I have created a survace in Catia V5 using "Multi-section surface". The splines that I have used are of order 5. Now I want to know what is the continuty of the surface.

What is the command that I have to use to check the order and continuty of a curves and surfaces. Any help would be thankfull.

Warm Regards,
bsvk

Try the Connect Checker.

Even better for determining order of surfes and surfaic curves, is the "converter wizard" in FreeStyle, if you have it. The default values should be the order. (and you can modify it, if you know what you're doing)

You can also use FreeStyle to extract ordered pairs using the "curve on surface" function, which can be individually analyzed. I generally prefer this method, for best results. (easier to interpret, but takes more time)

Just one more way, of course...

Thanks solid7.
I'll try your method. But is there any other way to to check with part design and generative shape design licence? we have very limited free style licence and getting licence is difficult.

Just the below questions poped up as I'm new to Catia.
-> What is the default order/degree of a surface created by Multi-section surface?
-> Is there any command like "information" like in UG?

Warm Regards,

Yes - there is. It's called "geometric analysis," and it's under the same tool palette as curve and surface analysis. It's got a question mark on it.

This will tell you the following information:

Type of geometry
if it's trimmed or not
number of components in U and V (ordered pairs)
Ordered patch/arc in U and V

It should be everything that you need to know about your geometry.

I don't think there's a "default" order to surfaces created by Multi-Section. A very apt explanation can be found at:

http://mathworld.wolfram.com/SurfaceOrder.html

Or, for the short of patience, I quote:

"The order n of an algebraic surface is the order of the polynomial defining a surface, which can be geometrically interpreted as the maximum number of points in which a line meets the surface"


I hope that helps.
