I am thinking of purchasing 3Ds for use in Rendering Architectural Interiors. I have been in construction for a number of years and found that most of my customers can not visualize Kitchens, baths etc. I am currently using Generic 3d to generate perspectives and furniture renderings for clients and find it very helpful and the customers love it. I have seen a demonstration of 3ds and it is very impressive. I would like to use so I may put color in my drawings and also offer it as a service to several Architects I work with in place of models. My first concern is development time. Would the rendering of a Kitchen, for example take more time than it is worth? Could it be done in say 10 hours? Also, perhaps there is another way I could get color and surfaces into Generic 3D drawings, say with Corel Draw which I have. Any input would be helpful. Thanks Don
