designing a backpack

mi.silva — Tue, 06 Feb 2024 01:54:18 GMT

Hello

One of our students is designing and making a backpack, he already cut the individual patterns and we have them as a fusion sketch.

To get one approximation of a 3d model of the bag what path should we take?

Using the form function? Starting with a cub and developing it further or somehow creating surfaces?

Many thanks

That's a bit hard to tell. How was the sketch created? In another program? Is there a visual reference for their design?

Hi,

As far as I know, the design process works the other way round.
First you model a 3D model and derive the individual sections from it (e.g.) using suitable software.

You can model in Fusion with surfaces and solid elements or with the "form" tools.
However, there may be other applications (Blender) that are more suitable for this purpose.

As an instructor I would not permit a student to select a project for which they have not been trained with the tools to complete. This would not have gotten past the project proposal stage - definitely a bridge too far.

I did traced them on top of a picture from the paper templates the student did.

making it on a cad software is not the main thing here, it would be a bonus though! The important was generating ideas, testing materials, develop the patterns, cutting the individual parts and sawing them together.

the process of modeling this thing in cad could easily be done as a extension of doing things the old fashioned way- by hand IRL. could be an interesting learning experience that would inform how the next project might be approached from a computer AIDED design approach. (which this case isn't in a sense. it's more of a pure drafting activity, the design done largely off the computer.)

so if I were expected to sew this together, I would probably aske for some kind of artists drawing of what it should look like, and/or a very good and detailed diagram of how the pieces go together.

can you get those things and post them?

The student modeled in 3D (physically) from hand drawing sketch and mock ups. and from there derived the individual parts.

It's exciting! I really went through a similar process when I designed my Louis Vuiton navy blue backpack using 3D design software for 12 O'Clock Club.

Here is the approach that did the best work for me:

To obtain an exact 3D model of the bag, the most effective path is to create surfaces from the existing pattern, instead of a cube or a solid start.

Suggested Road:

Import or track 2D patterns to software.

Use the surface modeling tool to add and shape the figure.

When all the surface is formed, you can include or sew them together to create a full 3D structure in the bag.

Finally, use thickness and details using the form or fixed tool.
