How about a workbench dedicated to clothes pattern drafting ?

Have some feature requests, feedback, cool stuff to share, or want to know where FreeCAD is going? This is the place.

How about a workbench dedicated to clothes pattern drafting ?

Postby maxagaz » Thu May 03, 2018 10:53 am

I'm dreaming of a workbench dedicated to clothes pattern drafting, a bit like the Valentina project here:
https://bitbucket.org/dismine/valentina

Is it something FreeCAD could possibly go for ? I'm curious to hear opinions about it.

Who knows maybe indeed Valentina workbench will be created someday? :idea:

Clothing pattern design such as done in Valentina is typically 2D work. What would be the advantage of adding this functionality to FreeCAD? Why can't you use Valentina?

I've had some experience in the past few months using a 2D pattern making program (we're not using it for clothing but for furniture). I can say that it is a totally different mindset and workflow to CAD. All geometry elements are B-splines (or Bézier curves, I'm not sure which).

We did look at a different solution, a pattern making module for SolidWorks called ExactFlat (which creates flattened patterns from a 3D solid). My analysis after comparing with truly dedicated pattern design programs was that a mechanical CAD program is not really well suited for such a task, notably regarding grading.

I tend to agree with NormandC, here. Unless there's a licensing advantage (Valentina is GPL3), I don't seem much value it would provide.

That said, Sketcher is obviously well-suited to this sort of task. I know that @microelly2 has been looking at better curve support in Sketcher, so this sort of use isn't far afield of the work he's been doing. Nevermind the fact that the academic exercise alone seems valuable. It's a very different use for FreeCAD, which presents itself as a general purpose modeler. Is the need really too far afield of FC's scope? Do the needed features require substantial core development?

Seems like this would have value in other areas as well. Might be worth investigating, at very least.

Ohhh, well. 2D and 3D... Maybe you shouldn't be so strict about the distance between both fields...
I have seen cloth designs with 3D printing... and 3D software for 2D animation...

Sure, FreeCAD has a priority list of features waiting... and limited manpower. But how people can use and get benefits from a tool is something that only imagination and creativity can see.

No doubt. I've been watching the Blender 2.8 features like a hawk. I love what they're doing with the grease pencil tool. This is another example of how Blender's ahead of their proprietary competition... Maya, 3ds Max, and Houdini have scrambled to keep up on a couple of occasions (like the fracture modifier that's also made it into the 2.8 release).

Anyway, I personally think it's worth exploring. It's just a question of whether or not it's a valuable addition to the FreeCAD ecosystem, especially since a specialized open source tool exists which already meets the need. The value (to me), would be identifying other potential applications for that workflow, or at least identifying missing features which could prove useful in other domains as well.

2D drawing of cloth patches and cut optimization is a 2D task, but the more interesting task is the way to fold the patches back to 3D and optimize designs for 3D. there is a lot of papers how to optimize cloth design (for example for sportswear).
I see here a project when our shoe design projects is completed.
There are many similarities between a shoe and cloth design. Only pockets and umbrellas are simpler :lol:
here is the link to the shoe thread

I think the 3d ->2d workflow which I try to implement in FreeCAD is suited for more technical cloth-designs. I posted one use-case already.
https://forum.freecadweb.org/viewtopic. ... ck#p217652

2d -> 3d simulation is doable in blender with the cloth simulation.

2d only: Allthough freecad has some tools, I guess it's better to use a specific tool like libre-cad or valentina.

Luckily FreeCAD is modular by design. And therefore making decisions if bringing something to FreeCAD ecosystem or not doesn't require general consensus.
