6. 1 1 Introduction What Is CADDSHADE II What Is CADDSHADE II CADDSHADE II provides advanced rendering capabilities supplementing the Basic Shading functions provided by the single window rendering environment Basic Shading is included with all base packages of CADDS 5 Basic shading allows you to render model data in a view s in either shaded or hidden line removed modes The rendered views can also be dynamically manipulated by mouse or spaceball type devices The advanced capabilities provided by CADDSHADE II include the ability to work interactively within the single window rendering environment any view can rendered in either shaded hidden line removed or wireframe modes You can overlay drawing mode information e g drawing annotation frames etc over either shaded or hidden line removed views or apply translucency to entities or components depending whether in the active part or CAMU instance it is also possible to have different rendered representations within a view that is some entities shaded others in wireframe You can the save the resultant image to a graphics file for downstream use using PLOT DOT You can use CADDSHADE II on surfaces and solids created with these PTC software applications e Explicit Solid Modeler e NURBS e Advanced Surface Design e AEC Structural modelling and routed systems applications You can also use CADDSHADE II on a model created in the Parametric environment when you activate it
