[mpfusion]

Problem description

The function “Add cosmetic line through 2 points” presents two sets of radio buttons “2d point” and “3d point”. However, one is able to (de)select each button individually. This is unexpected UI.

Radio buttons offer a selection to pick one out of many. If multiple or none of the options should be selectable, then checkboxes is the correct UI element. However, this dialogue offers radio buttons with individually selectable choices.

Furthermore, I suppose the Z field should not be visible if a 2D point is selected.
