New Interface - LITESTAR 4D has a new interface which has been studied to be particularly powerful and simple to use, and able to perform highly complex operations in just a few seconds. The interface is based on essentials, to avoid having a packed screen, and ergonomic, in order to simplify even the most complex operations Drag&Drop - all operations regarding the choice of the different objects (luminaires, furniture, DXF - 3DS - OBJ files….) can now be performed by using the Drag&Drop function which is extremely handy and dynamic OXL - LITESTAR 4D introduces a new data exchange format, called OXL, fully developed by OxyTech, which is just the natural evolution of Eulumdat and IES format files. The OXL file allows the management of the 3D file of the luminaires together with the corresponding photometries, all within a single file. There is a single OXL file for each luminaire and each OXL file can either be linked to the corresponding product in the Liswin catalog or be used separately Project-saving with photometric measurements - LITESTAR 4D allows to save projects including all the data regarding the products that have been used in it, including the photometric measurements of the luminaires. This consents the transfer of projects even to different programs without having to transfer separately the photometric file Disappearance of Fotom.FDB - the use of the FDB database, which was the photometric data management system of luminaires, has come to an end and will give way to the new OXL format and Liswin catalog to which the OXL files will from now on be linked Compatibility Windows 7 - LITESTAR 4D is now compatible not only with Windows 7 but with Windows Vista, Windows XP and Windows NT too. It can no longer be used with Windows 2000 New Licenses - the launch of LITESTAR 4D entails a series of changes in the Licenses for the use of the program as stated in the following options: Freeware License (free of charge) of LITESTAR Open: this is the LITESTAR Open License that can be downloaded from the Software/Download area of WebOxy (www.oxytech.it).
