Winding function

3D Design Volume Model
1

Hello!

I can't wrap my sketch around my shape... I have an error message that tells me that it is not an extruded solid body (I used the Thicken Surface function). How can I fix the problem?

Instead, do it via a sketch projected from an offset plane

It seems to me that you are trying to model a cosmetic bottle

go for 1/4 of the shape why not 

as the sight of your screenshot shows will the winding

you have your shape on the straight part but not on the narrowing and the neck

Question and why in surface

since I think but I could be wrong

that after your projected curve you're going to do a sweep ;-)

So the appropriate tool is a projected curve

@+ ;-)

The projected curve doesn't work because I want to keep exactly the same dimensions as on my sketch and the projected curve distorts it... I really want to wrap this sketch around my shape:)

4

And no, I'm not going to do any sweeping! I just have this shape, I have to wrap my sketch around it:)

Hello

Indeed, the projected tool distorts the sketch used, unlike the winding tool. But the winding tool only works on a single surface obtained by revolution, and yours is made up of several smoothed surfaces put end to end and then volumized with the thicken function. So it can't work,  but I think you have to go further back in your design and ask yourself what you want to do. Your approach doesn't seem to be optimized. There are a lot of illegitimate 3d sketches and functions with ambiguities of contours in particular.

As you rightly note, gt22  You should work on a quarter of your part, it seems to be symmetrical. This is the only way it can be, but when I took a closer look at your design, I realized that it is not. Not by much, but it is not.

The winding function is very specific and limiting. It should not be used for the proper design of a volume, with some exceptions. Rather, it is used to finalize a finished volume with a relief or marking detail. Normally, more universal tools should make it much easier for you to get what you want.

Put in black and white the geometric, aesthetic characteristics... of the product you want to get and from there it will be much easier for you to determine the path to follow to get there.

Send this to us and I will try, modestly, to help you

Kind regards

Hello

Another way to look at the problem:

- Copy of the volume body

- Surface projection on volume

-Intersection

- 3D Sketch --> convert entities (selection of the contour of the rebounded density)

7

Oops I forgot, circular surface revolution of the sketch to be projected along an axis tangent to the volume body

so take the decal function

I attach a word document with images, it will be easier to understand

Of course, but the solution recommended by A. Leblanc distorts the sketch because it operates according to the normal to the sketch plane and not to the surface that must be crossed. In any case, a plane sketch can never be applied to a left surface (therefore not adjusted) without deformation.

I still think that we need to review the problem further upstream and find out why this limitation is necessary. Is this sketch, sketch1, the projection of a silhouette? Where does it come from, it does not appear in the tree. What is the desired outcome?

In addition, there are the deformation or bending functions that can be interesting, make the cut flat and then bend. With the right settings, there will be no distortion;

 

Kind regards

Indeed, you will never get a projection without distortion of your 2D sketch on a 3D surface profile (left surface).

The solution I propose starts from a circular revolution with respect to an axis tangent to the surfaces of your part, which necessarily results in a slight shift.

Pierre Mihailovic, I don't think it's possible to realize this problem with these functions on this part, at least not without distorting the sketch. If you succeed, I will be curious to see the result of your method. However, rethinking the tree structure may be a possible solution.

gt22, the idea is good, but is it possible to use this (appearance) function with a sketch? It seems to me that this only works with images.

Hello

I think I've found the solution to your problem. You have your development and your form of arrival. If you create a tool to stamp your part, it should work. You will need to extrude your sketch that you want to roll up. I could only try it tonight.

Hello, if you shift the axis of revolution by 5 mm in relation to the volume body, the intersection is practically on the segment of the coiled part. Of course, it's not ideal, but it can help.

I try to find a solution but I can't do it... How did you find the dimensions of your flattening (Sketch1)????

16

In my opinion it's impossible because you have a PB with your devellopé... it is much smaller than your formed part... 1 or 1.5 mm ok but now it's still more than 5mm.... I find a dev of ±151.15

Well done @ AC Cobra

First of all, define this sketch which because of the support is not at the price

which of + is it seems that the 1/4 of this bottle is not very successful

I can't see symmetries

for the horizontal symmetry ok although see  the fitting

But the vertical symmetry leaves me perplexed..... doubtful ;-(

question already asked ;-).............. but what is the purpose of this sketch?
