How this can be possible?

How can this be possible, a line in REVIT that measures 7mm

[barthbradley]

Meters? 

[ToanDN]

7 mm distance is entirely possible.

[barthbradley]

Probably got away with it by Trimming the Line back. 

[yes_and_no]

That was not 7mm by the way.

Should be 0.7mm, if my metric system serves me well.

[Darwin33]

I ve heard the limit is 0.8mm

Try modeling something with a sketch line less than 1/32".
