There're a few things you can use to change the settings.
1. There's a View Option to show Length/Width of an object:
2. There're operations in the right-click menu to set Length/Width of an object (work for multiple objects):
3. There's an option in the System Setting to auto set the longer edge of an object as length:
For now please let the user turn off the "Take Longer Edge as Length" option in the System Setting, then the issue should be fixed.
(The "Set Longer Edge as Length" feature is a legacy problem inherited from the "StoneCut Web embedded" old versions where we need to export StoneCut Template then upload it to StoneCut Web to get the cutting results, we'll remove it in the next release)
