you are right max in the end depends on the production, and all the speech on the g3 or g4 continuity is nice to see itself graphically but above all it serves catia or alias automotive to sell more.
as for rounds: so I should do surfaces with the basic tools, work on trim and merge, then by the edges that are shaped with variable radius rounds, conicals etc.
Is that right?

Hello everyone

I would like to know if pro/e is able to create class surfaces with continuity c3. example if I put the curvature bond between two splines I get a result as in the image, it doesn't seem like a g2 continuity, it can become if I work on it but so doing I can also become a g3 continuity to the eye. and with the surface the result is even worse. What I wonder is whether the curves created in the isdx module are fake or not.

all your advice or experience and well come.

Thank you.

Hello.
about class surfaces to... I would like to know if there are tutorials, manuals etc because I want to learn well

Hello, everyone.
exists a manual that can be purchased that speaks of class surfaces a, which explains the surfaces for aeronautics and automotive?

I have followed your debate, I am using proe and the isdx module, and I have also referred to the myths of warp continuity. my opinion is that to model details in which perfection and continuity are really needed beyond g2 we must rely on other software. in my opinion alias is unbeatable in this. indepensable according to me model parts of body shop with pro e.

I quote those who say that these "works of art"we will have to produce them, and if you do not have the tools or, worse still, there are no tools to physically obtain the desired geometry, then the g3 continuity becomes useless (and not productive because it loses time in its research).
that I know, the class surfaces a are a diabolical tool invented by catia when only she existed, then the concept with all the other cads that came after.
I think that at the level of mechanical design, a tangency curve well connected with an optimal length and inclination of the tangent is already a lot of stuff, then if we want the works of art (in the limit of possible) we have to go to talk to the cammista and the operator on the machine, putting in mind some screams, disconcerting blasphemies and insults to the mother before they start to take you seriously.
I work in the automotive field and I work in the fanaleria, and without the experience of moulders on the machines, I could do all the g1/2/3 surfaces of the world and would always come a bowl.

Here, I add that for a couple of years I have made the calibers for the details of your industry (if you see my origin, it will not be difficult to understand for those I have worked); for rps dowels that copied the surfaces, I never used the isdx (although I had a floating license), even in cases where I had to rebuild small areas and never had a problem when checking with the customer, even with the long lenses of the new 8 bmw series.
