Is it possible to fold a body around another body?

Hi everyone,

it's been a while since I came here. I need your help to let me know if my project can be done with Fusion 360.

Here is my hand scketch to explain my project. It is not perfect, I just want to give you an idea.lampe plan.jpg

I would like to create a wood lampshade that would be attached to this old IKEA lamp. I need to create a sketch that will be readable by the laser cutter. But I also wish, if it possible, to create a visual with Fusion 360.

 

Is it possible to take the body that will be generate by my sketch and folded around another body or maybe a spine? I looked for the metal sheet but, I'm not sure I'll be able to create what I want with this function.

 

If not, I will need to trick my lampshade so I can extrude an empty square and them create holes that will represent the wood hinges on each corner.

 

Hope my whole post is clear enough. In my head it is clear but sometimes I find it diffuclt to translate my thoughts even more in English.

 

Thanks in advance for your answers.

Here's my attempt using sheet metal.  Is this close to what your trying to do?

Well thank you for your quick reply, Laughingcreek!

Yes that looks like what I want. But if I understand, in this case, the file can only show the result for this lampshade, but it can not be sent on a laser cutter as a sketch.

You did a great job, I'm trying to understand the storyline (don't remember the right name).

 

If it is the only way it can be done, well that's ok. I will do the sketch for the laser cutter on another software. Or maybe I can to it anyway on Fusion.

That's one of the primary uses of the Sheet Metal workspace.  You just need to Unfold the design, then create a sketch on its face.  Project the body to the sketch. Save the sketch as dxf.  Send to laser.

In the sheet metal space you can select flat pattern, and export a flattened version of the shape to  a DXF file.

If this general approach looks like it might work for you, I would suggest reading up on some threads using sheet metal to wrap around things.  There are quite a few.  Here's a good thread that (I think) kicked off the whole craze of using sheetmetal to wrap things.  A good read-

A side note.  Since this is intended for sheet metal, it takes into account the fact that sheetmetal stretches and/or compresses when it is bent in a brake.  So the flat pattern may have slightly different lengths at the bent regions to allow the metal to stretch.  You may have to fiddle with the material settings to get things to work out right.

You got a thumbs up from me, because you went through some effort to explain the problem at hand and also created a hand sketch to explain the problem in brilliant clarity.

 

This is very rare these days!

Thank you so much for your explanations, Laughingcreek!

I will definitely check how the metal sheet works and how I can create a sketch based on the unfold sheet.

 

Thanks to your intervention, I will go a step further with my knowledge of Fusion 360.

I really appreciated!

You might do well to compare the product of the Sheetmetal workflow with exporting the Body to Meshmixer for using it's Unwrap process.   Alternatively, given the wood will be compressed and stretched, that this pattern is uniform in cross section, you might Inspect the inside and outside Edge measurements, add them together and divide by 2 to produce an approximation of value.   Or you could just Sketch the tube profile and Offset the center path to find the same vale.   Or you might do a search for laser kerf bending, as this challenge has been previously confronted and automated processes created- as I recall, there are several free applications for producing patterns for both kerf bent forms and related joints.

Or ... you leave the CAD design as is and just make the part.

Then take a few measurements from the physical artifact and change the design of the pieces it interfaces with and then make those.

 

No need to overthink this!

In fact, that seems to be the must simple solution.

I can create a prototype, test it on my lamp wire and then make the modifications if needed. But I wanted also to have the 3D Model. And since it can be a project that someone would like to create, I just want to be able to explain the process to achieve this kind of project.

 

I might work on this project durint Christmas vacation. So as soon as I will finish thie lampshade, I will post the result here!

 

Thanks again to all of you!

It's been a while but I did not thank you for your comment! And I just want to say I appreciated!

I need to create hand sketch when I'm creating project. Otherwise I might not be able to see all the different possibility how to fabricate the object. And I know that it is the better way to explain it to someone when needed.

Is it possible to fold a body around another body? Yes. Yes it is.

 

Oh...you mean in Fusion 360?
