An interior design software package written for MS-DOS micros from the Osnabruck-based DVC DatenverarbeitungsContor GmbH has won heavyweight backing from the direction of Paderborn. The product is to be marketed in Germany by Nixdorf Computer AG on its MS-DOS machines under the name Nixas Raumplan 3D. Aimed at designers of shops, banks, offices and exhibitions, the package allows users to key in details of office fittings, which it then stores to form a basic designer inventory. Designers can then experiment by programming the system to combine any number of the fittings in a pre-specified amount of space, and, once presented with the results, can use the screen to indicate alternative positions from which they wish to view the proposed interior. Results of this rearranging of the furniture and the decor arrive on screen in under a minute, and can be printed out, together with a detailed list of the fittings used.
