Good day.
Is there a way if your drawing is set in inch and you want to measure and or confirm the measurement in metric to have the dimension to show this in metric.

even better if it show both...yes I work with both at the same time lol.

also for instance if you want to edit a line length to convert to mm?

Tnx.
