I liked how simple the software was and easy it was able to go from absolute beginner to a proficient technical expert on the subject matter. I was then able to train people within my project to use it in their daily work life.
I also produced very advanced technical drawings used my trade workers on my project, it effectively delivered my message to the team each time and was able to use their comments to better myself.
It was a little slow when transferring 3D models to the 2D Layout program, not so slow as it ruined my productivity but when the models got to large it was noticeable. A better computer would alleviate this problem.
Learn how to best used the Scenes feature and how to cut sections in order to transfer over 3D files into the 2D Layout program. This will help you always get consistent 2D drawings.
I was using SketchUp for Design and Drafting of Formwork Systems used in a Hydroelectric Power Plant. I was able to 3D Model the entire structure and once completed that model I was able to design my Formwork around it. I then took that 3D modeled formwork and used Scenes to transfer those 3D images to 2D drawings using SketchUp Layout.
The whole system worked great and once the model was setup you can go back and edit the 3D model and it would automatically transfer over to the 2D drawings.
