My favorite feature - with this, you can easily draw your line in 2D to create complex geometry from simple shapes like box / sphere etc., The material properties are very accurate which was surprising considering how easy it's supposed to be just using this software! It requires good RAM as well but I guess they have now fixed those memory problems by updating with more cores. Sometimes its bit cumbersome when working along side other programs or having some open documents while doing drafting work so try getting everything done together then export them into CAD where all errors will get caught automatically unlike paper work only approach :) We use rhino mainly because we did our masters project, which helped us understand 3d modeling fairly comprehensively even if had no formal background before which helps me whenever i need something related to modelling! The most useful feature of RhinoCAM is the ability to create a part and then save the file to a format that can be used in a CNC machine. The software is easy to use and the interface is very clean and intuitive. I have not found any other features that I dislike. I have used RhinoCAM for creating parts for my CNC machine. I have also used it to create 3D models for my students. The software has been very helpful in my work and has allowed me to complete projects in a timely manner.
