It's very easy for non-technical persons like me or my customer/client friends who want their homes built in Australia! The software is intuitive as well even without technical background knowledge of building construction industry (like myself).
There are few things that I dislike but this doesn't matter much because it may be resolved by them quickly if you provide your feedback via support email address provided within website at any time they wish; no need complain about something which cannot get fixed easily. We have used many different softwares so far over last 5 years including 3D modelling tools etc., all were expensive plus required more skill than we needed from our end users i think - too complexed system where only highly skilled person could operate those complicated systems properly & understand what was going wrong when using these kind products previously before coming across 'canibu'lty'.
