As I mentioned before I have no clue where these phrases are used.
Crowdin context tells us they were obtained from the the Sketcher .ts file:
Key.Command[‘Add xxx constraint’]
Command
…
File: Sketcher.ts
Replace xxx with one of the following:
lock, ‘Distance to origin’, Distance, Symmetry, Horizontal, Vertical, Block, Angle, Equality, Radius, arc angle, concentric and length, DistanceX, DistanceY, point to circle, horizontal, vertical, ‘Lock’, relative ‘Lock’, fixed, ‘Block’, block, coincident, distance from horizontal axis, distance from vertical axis, point to point distance, point to line Distance, circle to circle distance, circle to line distance, length, point on object, point to point horizontal distance, fixed x-coordinate, point to point vertical distance, fixed y-coordinate, parallel, perpendicular, perpendicularity, tangent, radius, diameter, radiam, angle, equality, symmetric, Snell’s law, auto,
Some are in plural, Add xxx constraints:
‘Horizontal’, ‘Vertical’, Symmetry, Distance, Equality,
And one odd: Add tangent constraint point
I am trying to proof-read the translations and to find them in the GUI. If the translation seems to fit well in the location where I found it I’ll mark it as approved. But it is quite useless to approve entries that cannot be found anywhere.
It is useless as well to translate phrases that are not used, which seems to be the case here.
