Solid flattening from surface

[gfix68]

Hello to all I have to create the scale of which place the model, the mast that you will see at the opening of the file is created with a surface and then I added the thickness... now I should cut the piece but I need to "flatten" of course I can't because I can't create a sheet from that surface... there are other methods to create the piece and then can convert it to sheet and then stretch it?
Thank you.View attachment scala a chiocciola.zip

I can't create a sheet from that surface.View attachment 32989

Of course you can, I'll put the model on you.

 

[gfix68]

Thank you very much!!! I would say perfect... and easier than I imagined. ..unfortunately they are a little back with sheets and surfaces with solidworks!

Just one question, please explain the procedure? did you first create the "crash" then the sheet? or like... thank you!

hi gfix68, it is actually simple. I have created a model with this system from the surface, but I have never realized it.. However it should be 99.9% good.
to realize it is simple. you have to create 2 3d sketches where you go to copy the external (or internal) profile of the surface (command "convert entities") and then create the sheet with "folding with loft". The only catch is that when you do 3d sketches you have to be careful to have only one entity to sketch... after gates or disables or hide the surfaces and the game is made.. .
I personally did not understand how to realize the sheet that seems very large, perhaps of centintura to the bending machine?
If you have any doubts, please contact me.
Bye-bye, Marco.

hi... well I tried on other entities and it works perfectly. .. here things are done a little manually, the sheet has a constant radius... and the workers here "bearing" for the displacement, but now I have to "fly" every single piece of the scale... what do you recommend? Do I have to create 2d designs single and independent from the model for each piece and put in "no show" others or does there exist an alternative method? use solidworks only for a month...unfortunately. . .
Thank you!

 

[PiegatoreSolidworks]

I honestly don't understand what you mean, but I'd say you have to build the steps directly on the model and then maybe copy it or reinsert it on the board if they were all the same. . .

 

[gfix68]

Okay I better explain... the steps are all different... how do I flatten them and "float them" in a drawing? i.e. do I have to make a 2d design separate from the model for each single step? so that if you restore the 3d model then in the 2d do not change the views?
Thank you! !

I'd say you can develop one by one. I would say that you can create a sketch on the extruded steps and then put on the flanges that interest you or directly convert the extruded and turn it into sheet metal (command "converts in sheet" ) giving the thickness that interests you. certainly this last solution, at this point of the model, is ideal.

ok was what I "live" anyway I don't see alternative...thank you so much of everything!

still be quiet, the job is very quick!

Good afternoon bending!

First of all I thank you because using the function described I managed to achieve my development. the only note/comment I would have regarding the number of folds:
depending on the settings I get more or less folds however I believe that with a "conical tie" I should be able to achieve a more homogeneous result. In any case, the result I think is accurate enough, so thank you!

The other question I'd like to ask you, maybe more advice is about this other model. . . https://www.cad3d.it/forum1/threads...-sviluppo-componente-torto.53670/#post-419407substantially is a sheet that follows a curve but at the same time rotates homogeneously tot degrees (torsion). . .

my question would be: is it possible to use this function? or is it better for example to get a surface and use the flattening function?


Thank you so much in advance!

 

[MassiVonWeizen]

Another question I would like to submit, perhaps more' a council is about this other model. . .

if you attach a step you can take a look

 

[Conte91]

massivonweizen,

Here's the step.
I press that I'm working on the 2016 version and the dimensions are in inches.
I should get 3 sheets thickness 1/8" (just over 3mm).

With the method described above, you can't do it because it is, in my opinion, impossible to get a complete 3d sketch consisting of only one element. I tried but the only way would be to use a spline but it is not recognized as acceptable geometry for this function.

with the flattening function of a surface instead works, although when I check the compression and traction chart I remain a little uncertain. .

I think the result is good enough anyway. .
in another part I tried to use the 2 commands and compare the result.. with the bending command with loft I get a sheet of 1/16" longer than that obtained with the surface command.. Which seems strange. . [lamiera laterale della gamba del tavolo]I also attach an image of the finished project.Thank you very much in advance.

 

[MassiVonWeizen]

for flattening you mean that the cut-out piece is made from a sheet that is then folded into a triangle and then cake?
Or do you mean anything else?

 

[Conte91]

flattening refers only to the function "flattening surface

"

in the attached step file there is a body; that body will be obtained by welding 3 sheets, thus composing the sides of the triangle that constitutes the section of the "processed piece"

 

[MassiVonWeizen]

Okay. the fact that you used the sheet and flattened terms made me think about the actual development of a folded sheet and then cake.
So I don't understand, what's your question?

 

[Conte91]

procedure for the construction of this piece.. Also because a double fold like that is in fact possible by our means.

my question would be: is it possible to use this function? or is it better for example to get a surface and use the flattening function?

at the dawn the question was whether it was possible to use the same function as "folding with loft" for this other case I described. (step)
I responded by saying that I couldn't create a single entity in a 3d sketch that could meet the requirements, having only managed to create a single spline that is not acceptable by the function of "folding with loft".

I asked for a comparison between the function "folding with loft" and "flating surface

"
can be used for the same purpose?
I tried to do a test getting a slightly different result and pointing out that, in my opinion, the compression and traction chart provided by the software in the surface flattening function is a bit strange but however the result seems acceptable to me.

So basically I'm asking for confirmation of someone who knows and has worked on similar cases so as to have a constructive point of discussion and, who knows, maybe I'm ignoring some function that suits me.

thanks for the attention.

bending with loft is a function that is part of the modeling of the sheets. with this function you have to give an initial profile and a final and you cannot give guide curves. therefore of its is an impossible function to use to obtain that particular.

instead you can use the normal loft function by giving it the initial profile, final profile and how many guide curves you need, but it still remains an unsuitable function.
as the profile remains constant then use the sweep function using the initial profile and a curve also you can set parameters like the twist. the curve will be created through the spiral propeller command.

sheet metal controls should be used when you want to achieve a plane development of the particular.

the surface flattening function is not present in 2014 so I can not pronounce on it.

 

[Conte91]

In fact I generated the body with a sweep and however I think that if it were not for the 3 elements that constituted the path of the sweep I would have managed to use the function of "folding with loft".

the result I wanted to get was a plan development of the particular however I believe the ambienta sheet in general has some limits for certain unusual folds, like these.. .

for example in the case that I managed to solve with the bending with loft (thanks the bending user) I had a conical displacement, the result with this function was a piece with many folds.... see below

depending on the settings I get more or less folds however I believe that with a "conical tie" I should be able to achieve a more homogeneous result. In any case, I think the development obtained is sufficiently precise, so thank you!

I believe that in these cases we should rely on the surfaces and I am pleased that solidworks has implemented them (while for example inventor has not done so with the same success)

thanks anyway for the collaboration!

 

[MassiVonWeizen]

the 3 elements that constituted the path of the sweep

the sweep asks only two parameters: profile and route

I would have been able to use the function of loft padding

absolutely not to do that solid, because that function does not accept curves guides or other types of path. is then made to allow a flattening of the sheet and therefore does not accept twists.
