diversified sform

[stef_design]

Hey, guys, I have a problem with solid modeling.
typical example of modeling plastic objects.
I have a solid (example a parallelepipedo). I have to shape the inner wall with 1st shape and instead the outer wall with 0° shape (i.e. without).
Plus the solid is radiated.
How to proceed?

i° road:
1-make the solid;
2-I make the sforms and then the rays;
3-the empty.
I get an internally and externally shaped solid. But it is not my goal. what I want is to get a solid, radiated, with 1 st in and 0° out.

ii° road:
1- I make the solid;
2- I put the rays;
3- I empty it.
the problem is that catia does not allow to insert the sforms after the rays.

How can I do that? ?
thanks guys:finger:

Hi. Did you want to get this?

the sform worked even if the solid was radiated (see image) ...
I did 2 degrees only inside... what doesn't work is the inner radius that is not recalculated according to the wall with the sform, but it is cut and therefore not in tangency ... if before making the deform, remove the face and remove the inner radius on the bottom, then do the deform and put the ray back in place...
or do 2 leotards, one for the outside with rays, the other for the inside with the sform + the rays and subtract them.. .
These would be my assumptions... if I understood the question well.

Thanks tvi71it, that's what I meant.

some considerations:
Why did you use the radius function five times?
- the sform function works even if you select the walls + the rays?

Do you think this works with complex mathematics?

ps: Can you tie me the chain file?
Thank you very much:wink:

I don't know if I understand your problem well... but I would solve it in the second way!!!
use "draft reflected line" which is a dot function
for the sforms that end up on the rays.
I'll attach the image and hope I've been helpful.

thank you rich, it was exactly what I was looking for:finger:

according to you, does it also work with complex mathematics?
Get me a curiosity, what do you plan with catia? : bye

 

[inbomba]

complex mathematics with catia is always an unknown.. .
in the sense you have to see what you mean with complex and how the model was struturated with previous features. I can tell you that the command is powerful enough and it also works to deform faces obtained from surfaces.

with catia I worked in the electrodomestic (pordenone zone and rear fanaleria for car. What are you doing?

thank you very rich, hello:finger:

It also works by beaming in one command... I did so... say by habit. . . Since it does not pass day that I should not change something, and it happens, by the law of murphy, the only possibility of modification that I had not foreseen in the construction phase is that which always asks me to do... forcing me sometimes to disassemble what I had done.

the deformed function, when you select one of the inner walls, with the propagation in tangence, highlights all the faces; However, the internal radius is not correct, it always has the problem I told you before.

the inbomb solution, solves the problem of the radius, but attention that at the top is reduced the thickness of the material due to the effect of the surface with the sform that is created starting from the reflex line... But if that's what one wants is correct.

with regard to complex mathematicians, as I am far from expert in using v5, I have always been for simple things, those that allow me to manage any modification, even what I remotely even imagined; each mathematics should be evaluated individually to identify the best solution. . .

I attached the file made with v5r19.

thanks tvi71it...to the next:wink:

I take this discussion to take some doubts about how to proceed in the execution of deformities. what I would like to know is if there is a right strategy to perform the sforms when dealing with models of complex geometries, i.e. it is better to make first all the model without shaping and then to apply them at the end or as you proceed with the modeling go to shape the walls?

thanks for the attention

It's always better to turn and shape the model at the end.
this helps both the calculation phase (increases the speed of regeneration of the model) and any errors (almost always caused by rays and sforms jumping).
Hi.

 

[bboyfab]

only that when dealing with complex geometries you can't almost never or at least I can't.. maybe it's because I make the model like a single body? better design the model as more body, shape them and then assemble them?

Thank you.

Yes, too. Can you attach an image?

Hello, everyone, I'm sorry if I interfere.
I'm doing a tour of the various sections and I've seen this discussion that interests me too.
I often make 'complete' geometries and usually proceed by disforming immediately.
some coast or poppetta maybe I leave it at the end, so also the fittings (not the functional ones though).
a question: radiating on two deformed faces generates a cylindrical blend, shaping the radius with the faces generates a conical blend. I prefer the first, you?
Hi.

Hi.

the conical blend is at the discretion of the designer (for me). I prefer the first.
