Re: Dimensions bug and snapping
The length is based on actual pixel precision: when the plan displayed at screen is small, a difference of one pixel can make a difference of centimeters. If the plan displayed at screen is large, the distance between pixels is more accurate when converted to a length.

It is understandable that there is no millimeter precision.
It is always arguable, some users could say that 1 mm is important for them, some others prefer 1 cm precision!
So, I decided to use the rule explained above. It's up to users to decide the method they want:
- zoom in or out when they double click to create dimensions,
- draw precisely dimensions by pressing <enter> key and entering the exact values they want,
- draw dimensions quickly then zoom in and adjust the ends of dimensions
- draw dimensions then adjust their length with dimensions modification dialog box added in version 7.2.
