migration from catia v4 to catia v5 - modules/licences

[dadigno]

Bye to all,
I have to face the passage from v4 to v5 and it seems that the configuration more similar to the add (v4) is the hd2 (v5). someone told me, however, that in the pure hd2 configuration, there are no surface modeling functions and that therefore, most likely, I need to buy apart the fs1 module. Can anyone confirm or deny this?
or, can you tell me if there are other functions/commands in the hd2 that allow me to replace the modeling functions of surfaces present in the add?
Thank you.

Do you need cloud surfaces for your work?

Hi.

hi ferrezio,
Thanks for the answer.
a priori it is a little difficult to know, let's say that if it is a function that I have in v4 I would like to find it also in v5, maybe it will be called in another way, surely it will work differently, what I want to understand is if in the passage from v4 and hd2 of v5 I go to lose something as it could be the function that you tell me.
Thank you.

Hi.

I do not remember the add configuration, but according to me hd2 covers widely the needs related to surface modeling.

coming from v4 the environment of the gsd will seem a little bit thin but it is linked to the fact that most comendi have been grouped.
to give you an example, in v4 the command that relimitated the arches was different from the one used for the surfaces, in the v5 the command is the same.

Perhaps the only thing you might not find is the possibility to create the so-called "higher-order archives", those that normally identify with *ccv, and consequently the surfaces that are derived from these.

all this is now part of the fs1, but normally these are the prerogative of those who make style surfaces, which normally makes industrialization, serve as support to derive lower grade geometries that you realize with gsd.

I hope I've been helpful.

Hi.
I was very helpful and thank you.
a question, for example, is the possibility of changing surfaces through control points possible in v5 with the only hd2 ?
what I did in v4 with patch ctrl point to understand. . .
Thank you.
Bye.

the last time I saw a v4 was 1999 (and I say only seen... unused), so I struggle to remember in detail the function you ask, you should describe the function so that I can trace back to the equivalent command. . Unfortunately I remember only the fundamentals of v4.

hi, we in the company made the passage v4 > v5.
But I wasn't there.
I write to you what my colleagues told me about.

in the passage from the v4 add module to the respective v5 hd2 module, they lost their functionality. Specifically, on surface modeling, to do what was done before with add, now in addition to having hd2, you must have the module fs1 (addon module purchased separately from a hd2) license.

Hi.

Bye to all,
@ fertium
the above command trivially allows to select the surface control points and "throwing them", along a director, modifying the final form, can I do the same with the commands present in the hd2 configuration products?
@ stef_design
That's exactly what I'm talking about. what is not clear to me is if, with other functions/commands present in the hd2, I can cmq get the same final result, obviously without having to make roe or mortal jumps.... a subtle difference that is worth more than a few k of euros.. .
Thank you all.

This is an fs command you do not have an equivalent in gsd.
I find it curious to know that this function is used to keep a surface under control, since you have no sensitivity on the deformation of the surface, unless the point belongs to the surface.
I would like to know a concrete exempt where you used this kind of surface.
However the underlying problem, for those coming from v4, is that the surfaces are modeled explicit mode.
in this mode, for example, the arches that are created to define the surface, once the latter is created, the first have no control over this, so it could be convenient to convert the surface into nurbs, then to deform it in a local area.
in v5, on the contrary, all geometries have a father/son relationship, so you can always mofy geometry, changing contextual paramneters, at this point the need to find shortcuts is less.
the same sketch that exists in v4 (but never used if not for solids), the v5 changes the approach in the construction of the arches.

From my point of view, but maybe it's the habit of v5, I don't see the need to have nurb maths, especially then if you have to deal with industrialization of product, vice versa if you do style, so you are unscrupulous to some rigidity of the work processes, it is convenient to have commands that allow you to pull overfish without direct control.

hi ferrezio,
what you find curious sometimes can become a utility or even a necessity, especially when you find yourself having to handle things that come from other software, so as is.. and you don't need to have to control what you are doing.
The example?
how do I quickly change the trend or banally to tangle two surfaces that come to me not native v5?
I do not know if there is a different way than that of v4 in order to be able to do it in v5 with the tools available to the hd2 configuration, what I want to understand is if I am actually unable to get the same results that I got easily in v4 with what is sold as "add -> hd2".
In addition to the individual example or the single requirement that others may not have, I find a somewhat incorrect policy (and I refer to those who sell ) to say "all you did with the add you can do with the hd2" if then in front of a trivial example like the one above I am asked to buy an additional form.
and I find it equally incorrect to think that in order to do it in another way I have to miss the triple of the time I used with the v4....
I find it incorrect because it would purely have a commercial motivation, should include this default feature in the hd2 configuration if they say that "everything you do with the v4 add you do with the hd2 in v5"
I wanted to understand if it is actually so...
thank you for the attention and for the answers you gave me, I think at this point you have largely confirmed that the v4 add in fact is the hd2+fs1 and not the pure hd2.
greetings

to do this is the "component" function, which does not need the fs1 area.

I think the problem remains only that you have to radically change the approach to work.
but I recognize that this is easier for a non-user v4.

Hi.

 

[dadigno]

interesting..... with the "component" I can get the same result I got with the v4? frankly I tried but I couldn't... (see Annexes )
It's just an example, but it's to make you understand what the needs I could have. .

 

[ferrezio]

or finally some interchange! !

I should still understand from which surfaces start with v4, but to me it simply seems a fitting that you can create with a law or as in the image that I attach you with a connection surface.
the composition serves to close a series of pachs and ensure the tangence on the edges.

Hi.

 

[dadigno]

... let's say it's not exactly the same thing/result (see Annex ) ... in this specific case I may also "displease", but this does not remove the deficit that I cannot manage the control points of a surface as for example if I want to control a flexo or other... or other things about bows etc....
I gather ideas and maybe I'll give you some more targeted examples, work allowing.
for now thanks for the dedicated time.
