feature Request – Mirror Sketch Lines, Holes, and Points

[structurednewstore-rgb]

I'd like Layerling to add a simple Mirror tool in Sketch Mode.

Users should be able to select lines, circles, holes, points, and other sketch geometry and mirror them across a selected line or construction line. perhaps even work off origin references x, y lines as well

The mirrored objects should be independent copies, retaining their original dimensions and spacing relative to the mirror axis.

No parametric linking or automatic updating is necessary. Just a straightforward, accurate mirror operation.

This would make symmetrical parts, hole patterns, brackets, and mechanical designs much faster and easier to create without adding unnecessary complexity to Layerling.

In Tinkercad the ability to do this is possible, although not as elegant as you've described. But the same method is not yet implemented in layerling, which I think would be good to add as a bare minimum:

In Tinkercad you create an Extrude Sketch and then duplicate it -- same as in layerling -- but then you can change the dimensions on one side to an equal but negative value, and the shape will flip (or mirror); then it's just a matter of moving the mirrored version until it butts up next to (or even overlaps) the original. It remains two separate objects in Sketch, but it's a single symmetrically-mirrored object upon exiting.

Going back to edit allows control over both objects again, although changes to one does not affect the other... so you need to delete one and repeat the pseudo-mirror process again.

In layerling the positive-to-negative trick doesn't do anything, neither in Sketch or the main Editor. I agree there should be at least a basic way to perform a mirror function in layerling's Sketch -- and perhaps replicating Tinkercad's negative value method would be a good start.

@structurednewstore-rgb, @prmod3d thank you, that was a fair wish and the sketch had no mirror. I added it: select points and lines in the sketch (click, Shift and click, or pull a frame round them) and click Mirror in the bar. Then choose Left-right (across the vertical axis through the middle of the plate), Top-bottom (across the horizontal one), or Across a line and click a straight line of the sketch, for example a construction line.

The copy is added on the other side and the original stays; nothing is linked, so you can change each on its own. Points that lie on the axis are shared, so half an outline whose ends sit on the axis becomes one closed outline: draw half of a bracket, select it, mirror it and make the body. Circles, holes and curves are mirrored too.

@prmod3d the negative value does nothing in layerling because a size is always positive here; Mirror does the flipping instead. The guide has the steps. It comes with the next release.

@structurednewstore-rgb, @prmod3d the mirror in the sketch is out in 1.88.0: select points and lines and click Mirror in the bar, then choose left-right, top-bottom or a straight line of the sketch. The guide has the steps. Reload the page to get it; the installed app needs a restart.

Works great. Thanks!
