midpoint line

[structurednewstore-rgb]

Add a Midpoint Line Tool in Sketch Mode, similar to the functionality available in Onshape and other parametric CAD programs.

Suggested functionality:

Center-Point Line: Select the midpoint first, then drag outward to create a line extending equally in both directions.

Automatic Midpoint Constraint: Maintain equal lengths on either side of the center point when resizing.

Midpoint Snapping: Automatically detect and snap to the midpoint of existing lines and edges.

Construction Line Support: Allow midpoint lines to be used as construction geometry for alignment and reference.

Dimension Control: Allow precise entry of the line's total length and angle.

This would significantly improve sketching efficiency, particularly when creating symmetrical geometry, centering holes, aligning objects, and establishing reference geometry.

I think it was said early on that @henmedia did not want this to become a parametric modeler, but these enhancements would be very, very beneficial. And since the sketching feature is on the 'advanced' side of Layerling, I don't feel they would intrude on the beginner's learning curve at all.

i do not disagree and i have been working on getting basic sketch tools: referencing the original sketch, mirror and construction lines, adding points as measurement dialogues etc. I dont want to replicate onshape, fusion etc but we can get to 60% which will make many kids and other users lives much easier

we also need the center of a circle /hole

if we want to attract new 3d printer owners, we have to provide a way to allow the users to edit a STL file they find online and need to edit slightly.

@structurednewstore-rgb @RobbieKnobbie @BigToyBox A point in the sketch now snaps to the middle of a line, to the center of a circle and to the middles of the sides of a body underneath. There is also a new button "Line from the middle" in the Draw group: click the middle first, then the end, and the line runs the same length to the other side. It is not a constraint, the two halves stay independent after you draw them.

@structurednewstore-rgb @RobbieKnobbie @BigToyBox this is out in 1.93.0: a point in the sketch snaps to the middle of a line and the centre of a circle, and there is a new tool, Line from the middle. Reload the page to get it; the installed app needs a restart.
