SgCore is a powerful geometric modeling engine designed for programmers and engineers who deal with 3D modeling. A user-friendly interface, an abundance of functions to create the most complicated objects and manipulate them, the small size of the library itself, full documentation and 24-hour technical support, all make sgCore a natural choice for any 3D programmer. In the sgCore library, Geometros has realized a great number of 3D solid-state modeling functions. Now programmers can include features of any 3D editor and CAD system into their programs and dynamically model even the most complicated objects. You can also use sgCore as a base to create your own modeling systems. The Geometros Company is developing the SolidGraph CAD system based on the sgCore library. Thus, new geometry and modeling features necessary for CAD system will be constantly added to new versions of sgCore. Additionally, registered users can influence the functionality of the new versions of the library by simply sending a letter describing what features they would like to have. As a registered user, you will also receive a free upgrade to the next version, 24-hour technical support and hot fixes of any discovered bugs within 1-3 days. SgCore with its numerous functions for 3D and 2D modeling and robust algorithms for creating and editing most elaborate objects provides everything you need to develop a fully functional CAD system. The chargeable version of SgCore offers such useful features as loading AutoCAD SHX fonts, creating text and dimensional objects (distant, radial, diametral, angle), saving objects in the user-defined formats and loading objects from a file as well as DXF import/export. The team of Geometros developers is now working on widening the sgCore functionality to the point where it is possible to construct photorealistic scene images.
