2d dimensions on a model

Can you give more explanation? With example model and how it must work?

Hi
You might want to check out the “Custom Image” example project in the App Manager. It’s puzzles for adjusting length and width of the picture frame to the incoming image works nicely without shape keys by just using 2 bones to move the vertex groups at its corners, which you could do with vertex groups at the end of your lines.

I have a debugging x/y coordinates on screen readout for my own use not users that have the letters x: y: as images. But the actual readout letters are blender text objects that every frame updated to an objects x/y coords on the screen. (You can lower the geometry resolution of the numbers in the text data bock for less bloat)

You could work the coord variables into being computed from the bone movement (or whatever UI handle you have constrainted to the bones.
