    Development History of gCAD3D

    What gCAD3D can and cannot do

    It can

      Import and display data from Iges, Step, wire frame and solid objects
      Create and modify wire frame elements
      Create surfaces
      Create simple solid bodies
      Assemble user-created ancillary programmes
      Export wire frame elements as Dxf and Iges
      Export surfaces as Vrml-1, Vrml-2, obj, tw Iges

    It cannot yet

      Create or modify complex solid bodies

    Multi-model support
    A model can consist of multiple models (sub-models) -

    Functions for creation / use of subModels:
    internal subModel
    external subModel
    CatalogPart

    Function to activate subModel:
     - only in VWR or CAD:
     - select modelname in browser-window with right mousebutton;
       - select "activate"

    Function to rename subModel:
     - only in CAD:
     - only the active subModel can be renamed
     - select modelname in browser-window with right mousebutton;
       - select "rename"
      NOTE: all external models, where subModel will be renamed, become changed
         into internal subModels.

    Function to remove subModel:
     - only in CAD:
     - only the active subModel can be removed
     - select modelname in browser-window with right mousebutton;
       - select "remove"
      NOTE: all external models, where subModel will be removed, become changed
         into internal subModels.

    Functions for documentation

      - Display of 2D drawings, 3D models and images in the same display space.
      - drawings/ models can be generated by scripts / templates
      - all display objects can be combined with interactions
