I like that there is an app where you can upload your drawings to get feedback from other professionals in real time, it's free of charge! Not so much yet but maybe one day (I hope) this would be available as well through 3D printing services or something similar? This could really help with getting more accurate designs when needed. A good tool if used correctly. It helps me create better projects faster by using my CAD system during design/rendering stages instead of drawing everything manually each step at its own pace which might take up too long sometimes especially those who are not very experienced designers / engineers themselves -.- I like the UI, it's very intuitive to use. It is also able to integrate with other software, such as Revit, so that design workflows can be streamlined across multiple disciplines (e.g. Interior Design, Structural Engineering, MEP). We are building an entire house in 3D using this software. It has been very useful to show clients what our vision will look like when finished.
