GstarCAD8 is a brand new CAD platform developed over 3 years. This platform is powered by a completely new engine and a number of innovative technologies to make its graphic speed and user operation 3-5 times faster while the memory usage is around 40%-50% less than previous GstarCAD versions. The new software structure also gives big room for further performance and improvement in the future, possibly making GstarCAD the fastest CAD platform in the world. At July 3rd 2014, Gstarsoft has launched a new GstarCAD8 patch version highlighted by the new 64-bit architecture support, which means the more data that can be processed at once, the faster the system can operate. There are several other advantages to a 64-bit system as well, most practically the ability to use significantly greater amounts of physical memory. In this patch version also has been added new functions related to annotative objects as well as important options within FIELD command and new custom hatch patterns and Linetypes. About improvements, it has mainly modified some important defects about CUI, FIND, Dimension, PLOT and so other commands. Accuracy and stability are guaranteed in this patch version.
