Complex surface / volume shape

3D Design
1

Hi all! :D

I have a 3D printer and I am also passionate about designing and flying drones. That's good! I can print drone chassis as a result! :)

In short, there are tons and tons of models on the internet that can be printed very easily, except that I would like to customize the chassis as I want etc.

To make the chassis etc, it's okay because they are rather simple volumes (because straight) except that for the "canopy"  

(That's what's in the picture, it's used to protect the immersion camera as well as the electronics), that's another story!

Here's what I managed  to do with my basics in Solidworks... Not very similar indeed! :D

There you have it... If anyone has the strength to help me (I'll do my best), contact me or put your ideas on this post please:)

 

Thank you very much, have a great day

Hello

Think in 3D printing and not as a SW draftsman!!

You don't have to reproduce exactly the model you have!!

your volumes with your 3D printer will not be easy to reproduce, so simplify your life and design your part according to the capabilities of your printer (printing volume, deposit of wire or resin etc ..)

All shapes are possible

See with the possibilities of creating the room 

A piece that goes with others must be created as a whole for good harmony 

after a detail

Hello

If you want someone to help you,  the best thing to do is to think like in aeronautics.

We start from each feature if they are known, otherwise build reserved areas. These areas are empty volumes that more or less accurately represent the space that will be occupied by a particular feature. So the other partners can build their piece without ever knowing the other pieces.

That said, I don't see how someone from a third party could help you with relatively simple models such as drones.
Here it's to help on SW itself and on features but not to do co-design.

On the other hand, if you can't model a part and you give a model, even freehand and with the main dimensions, then we can help you on how to go about it.


For example, your canopy is a free form made by surface deformation by pulling on it (like Rhino or ketchup) or it's surface and it's not quite within the reach of the beginner AMHA.

As for making proposals without knowing anything about all the components, then I'm drying  up ;-)

Kind regards

Thank you all for your answers.

To answer you, I based myself on the chassis of the drone with the location of the camera. I used this assembly: 

I have tried to work by revolution, which gives me a rather satisfactory result, although I have no idea how I am going to link the two revolts.

Otherwise, I'm thinking of starting to create a surface, it would help me a lot for these complex shapes.

 

What do you think?

Hello

It may not be as difficult as you think, start by imagining your piece in photos without the holidays and you will arrive on more cubic shapes.

Design in volume and then when you are satisfied with it make a shell function.

I also think that the opening for the camera should  be at the end.

It's just a way of thinking to reproduce what already exists.

Hoping to give you a guide on the "how to do"

I think you go into too much detail. (see my post which was validated late but which is at the very top)

Yes, I just saw it appear. 

The function is super interesting, I'll give it a try.

So if I understand correctly, I make this cubic shape and then I proceed by extruding matter in revolution?

The leave function should suffice.

C also a solution 

Knowing that the surface is a little more complex than the volume 

Good course

HS: Is it me where we lost the forum?? "

Otherwise to come back to the problem here is what I was able to do in the meantime: (not obliged to do the same but it illustrates my 1st post)

Nice @FUZ3D

Here is a part for a gyroscope ;-)

Kind regards

Well done! I love it, it's exactly what I would like to do, but less "square". So I'm going to take inspiration from your model by making a bigger chamfer. It's perfect, thank you!

Here's a simpler version:

I'm going to take the second option instead, so I struggled too much with the first :D

Thank you!

Just a question that will get a thorn out of my side, how do you do your chamfer from step 1 to 2?

Good evening fgg67

"Just a question that will get a thorn out of my side, how do you do your chamfer from step 1 to 2? "

Stripped down extrusion, I guess.

18

Exactly as Sylk says with an angle of 28° in my example.

19

So @fgg67 are you doing? they want to see us :)

Sorry, I stopped last night because I couldn't do it:D

Come on, I'm going for it with the stripped extrusion chamfer! Thank you
