Help for reproducing a part

3D Design Surface Modeling
1

Hi all

I want to reproduce this part on Solidworks. Given its complex shape, I have watched several tutorials on the surface but I can't understand where to start building it or what are the "right" tools that would allow me to achieve my goal.

I've been looking at it for several days, without really getting a satisfactory result.

I thought that a possible method was to first make the complex shape, i.e. the "cap"  of the part (the lower part on the 1st photo).

But I don't really see how and I must admit that everything is confusing in my mind.

I hope you can help me move forward.

Thank you in advance.

Hello

 give us some ratings

put a ruler on the photos (photo 4 to know at least the diameter)

the thickness of the canvas, the depth of the recesses, etc

for this piece I will leave for my part +

on half a piece since there is symmetry

and on the flat part in solid 

and will end up in surface

for the hat part as you say

Show us what you've already done

post your file

Thanks for the answer GT22.

I enclose the file 

I'm at this point:

I first made a volume body that represents the overall shape.

I then tried to make two projected curves to try to make the complex shape ("the hat"), a spline and a circle, one of them is only half drawn.

I'm a bit stuck at this level because I can't fill these two curves to form a surface and connect it to the volume shape I drew in the first place.

What functions should I use? Filled surface, border surface?

I am attaching a few sides of the object in order to give you an idea.

Thank you for helping me to see clearly because the time I spend on this piece is becoming quite delusional...

Hello

Personally, I have little knowledge about Solidworks...

But to reproduce an existing part, the best in my opinion would be to switch to dedicated software (for example, Geomagic Design X, which benefits from gateways to Solidworks)

A plug-in for SW exsiste too.

Thank you Rodalord.

Your solution requires a 3d scan, which seems to me to be a heavy artillery compared to this part. I'm sure that this one is not that complicated to model for someone who has a good knowledge of surface (which is not my case).

Above all, the part reproduced must not be completely exact to the original part. There is therefore a possible margin of interpretation.

I submit a .sldprt file where I finally managed to get two surfaces that make up the hat. However, I'm a little stuck with these two surfaces. I can't fill the space between them. Nor to convert it as a volume.

A little thumb cut that could make me move forward?

Thank you.

No one? :(

Otherwise, rather than ruining your life, why don't you create an easier room to perform the same function??? Instead of looking for a solution to your problem, see if you can't get around it! (e.g. see if you can remove the recesses and if you can reduce or even remove the delicate sides!?)

Kind regards

Having worked a little on your piece it seems to me that there are some inconsistencies between the blue and green parts

when you take over your file ditto

Here is the image of the volume profile via the extruded surfaces via the Surface Intersection tool

as well as an extrusion boss to fill the void of your surfaces
