locking in sketch

[structurednewstore-rgb]

When selecting an object, such as a circle, rectangle, or other sketch geometry, it would be useful to have the option to lock its proportions so that resizing maintains the original aspect ratio. I'd also like the ability to lock the object's dimensions entirely, similar to how we can lock objects in 3D Mode. Ideally, locking its position would be a separate option.

Again, my interest in Layerling is to help develop a lightweight CAD program that is approachable for youth and everyday makers, while still being accurate and functional enough for serious 3D printing and design.

I'm not looking to turn Layerling into Fusion 360 or Onshape. I think there's a real opportunity for something much simpler that still offers the essential tools people need to design accurately.

With the construction lines, snapping, midpoint tools, and other Sketch Mode improvements, I think we're getting very close.

The goal should be precision without complexity. Someone who's 12 years old should be able to pick this up and start designing, while an adult should still find it capable enough to create practical parts.

I think these simple locking features would be another good step in that direction.

@structurednewstore-rgb two of the three are built now and come with the next release. When you select an outline in the sketch, the bar that appears has Keep proportions: the frame's corners and sides then stretch both ways alike, and a width or height you type changes the other one too, without holding Shift. Next to it is Lock (or the key L): a locked outline can no longer be moved, resized, turned or edited, its lines turn paler and the frame loses its handles, and you can still start new lines at its corners. Unlock or L again frees it.

I kept it to one lock, as for bodies in the 3D editor, rather than a separate one for the position: two kinds of lock would be one more thing to understand for someone just starting out, which is the very group you have in mind.

@structurednewstore-rgb locking a sketch outline (Lock in the bar, or the key L) and "Keep proportions" are out in 1.95.0: https://github.com/henmedia/layerling/releases/tag/v1.95.0 – a reload of the page brings them.
