The solid modeling library sgCore (http://www.geometros.com/sgcore/review.htm) is undergoing active development. We have recently released a Mac version of the library and are now working on its iOS counterpart. We are also adding new features and actions – bending, twisting, corner and edges rounding, as well as import and export to various formats. Since our library was released 6 years ago, users have created around 30 CAD-like programs and 3D editors. We would love to know the opinions of our users – what should be added in the upcoming versions of sgCore, what other object creation and editing tools do you need?
