Confirmed here with latest 0.18 under Windows 7.
This behavior exists :
- Whatever is the base unit selected => You can enter -1'4" value when working in mKs, you'll get the same result
- Whatever is the unit used in the value => You can enter -1m500mm and get same kind of result
The only way at now is entering -1'-4" but doesn't sound very natural.
@metatheorem : as a sidenote, you can read from this thread
if you'd like to compile with Qt5 and OCCT7+
