As you know, Cubicasa requires you to scan the whole property in order to produce the floor plan. It need to be a unique scan but you can resume a scan that wasn't yet sent for processing.
You can resume any scan from where you stopped (remember there's no problem scanning multiple time a space). This allow you to tackle issue and organize your work.
When to use it
You completed your scan, but then realize you didn't capture the basement or a specific room, you can now add those areas without completely redoing the scan.
There's separate garage, it's raining and you want to do it at the end after leaving the house.
You want to work one storey at a time taking all the pictures and scanning it.
How to use it

Click on Continue scan
Press the record button, an instruction screen to relocate will appear
Press the relocate button, the image of where you stopped the scan is displayed
