Actually Sketchup is in todays CAD and architecture the most sung program. I think basically all architects use it in some stage of their work. I have been doing so for the past years.
In the beginning I thought Sketchup would develop ever more. Now I feel Sketchup will be as it is for years from now on. Since all now know the power of a surface modeller I see things are changing and many more capable programs are getting it right now too. If Sketchup does not catch up it will not fulfil its promises.
With Revit you build a database by modelling, with Modo you are free in shapes and forms, with Vectorworks you have an excellent tool for making your 2D drawings as well, with Sketchup you have a slow modeller with hardly any data to exchange with others. And the Sketchy edges has fallen out of style since rendering has become mainstream and rather easy.
I use Sketchup daily as well. But I feel the pressure to move on. I wish Sketchup would be sold to a defined CAD company instead of Google abusing it for their 3D world. Sketchup got stuck in their hands. Google hardly invests in the app were the competition does just the opposite.
Well, not to ruin your enthusiam, but you need to be aware that the ease of use comes with a price, unnecesarely so regretfully. I hope somehow the ever growing userbase will turn things around to a more professional Sketchup Pro.
