I'm new to Viso and want to use Viso to create a floor plan layout. As I the symbols on the symbol to draw various rooms and walls at the dimension that I want by reading off the measurement from the bottom bar where it shows the 'width', 'height' and 'angle'.

Questions
1 - What setting do I need to change s.t. I can set the measurement dimension to ft and inches rather than just ft only ?

2 - How can I have the measurement shows display next to the wall. For example, I have a room of 10' x 15' 5" and would like the measurements display as shown in the following sample diagram.
+--------------------------------+
|^ -------- 15' 5" ---------|
| | |
|10' |
| | |
| v |
+---------------------------------+

Thanks in advance for your assistance.
