User experience on adjusting building element - Door

[nthGH1030]

• Scrolling action
  Since there are multiple properties to adjust for door elements, user will need to scroll to locate a property. However the slider's value change event activates with a hover + scroll, user will experience unintentional adjustment to the slider value while trying to scroll through the properties.
  I would suggest disabling the "hover + scroll action", and replace it with 'click 1 time to select + scroll to adjust'.

• Measurement accuracy
  As for the sliding action, it would feel better to have the dots to represent 0.1m and align with the actual value, and represent 1m with a bigger dot.
