I think that time will tell if that is an advantage but so far I do not see it. There are lots of hobby or limited users (like me) because of free and low cost and the ability to control fine detail but how many people are fully adopting Sketchup to do the entire design in residential?
As a residential designer using a different program currently trying to make the switch is a fairly daunting task because of the lack of a well defined process and the tools needed.
I think that the plugins that you and other developers are creating are certainly headed in the right direction. I think you have really come a long way in the past 3 years and are creating a nice group of useful tools.
Really it is not having a general program and then having industry specific extensions that is the problem. The problem is that creating all of the specific tools needed just for residential design is a huge job. While it is nice that someone has finally developed a pretty good Electrical extension (for example) it is still incomplete. At least now it looks like I won’t have to add electric in the model for show and then add it again in layout for an electric plan.
How many more years will it actually take to get a full suite of tools that is needed and how many separate licensing agreements? How many slightly different processes from the various developers have to be worked through?
I think that this is really holding back wide spread use in residential construction. Just building a library of things needed for residential construction currently is a huge task that would discourage most people considering moving from other industry specific software.
Then also other issues like having to break the model into disjointed chunks to make it manageable (Sonders method) and having to export to Layout, etc…
I can see that with your and others work it becomes a bit more feasible every year.
