Current Auto-generated Layout is inefficient

[Pneumarian]

Continuing the discussion from Idea: New printing option: Coloured overlapping layouts:

@Sue

improve our current layout algorithm

Two problems I can think of,

1. it doesn’t have the option to layout according to grainline

@Douglas

Need to be able to force pieces on grain, allow for 45 or 90 rotation and allow // disallow to rotate 180 for one way fabrics.

2. I know it runs by algorithm, not intelligence, but sometimes it will fit two pieces into a something like ten inch space when allowed two feet, but can’t figure out how to do it when given 14"

• Clicking “Save length of sheet” often has it using more length than leaving it unchecked.

Yup… and that’s why I said for an average jacket and pants I can layout the pieces faster/ better. I’m doing it by what I’ve learned - or intelligence. I also know where I can cheat to fit pieces in… at least in the sense of a cut layout AKA marker.

This is one of those requirements of producing a marker that makes me think a better long term solution is to produce a proper marker section / module, rather than trying to cram more features into the existing layout section that only had printing in mind.

Hi Douglas, I would very much like to help you in the development, but I know little about C++ and I swear I tried to take the code and tried to do so. But to no avail. Is there any initiative to rewrite him in Rust?

Not really. We don’t have another 10 years to rewrite the project in Rust. Qt is natively a C++ based framework, and it’s just more complicated to use Qt & Rust bindings than just learning C++.
