Abstract

A method and apparatus for manipulating a computer generated model and visualizing a change in projection plane before entering a projection creation command. After selection of a projection plane on the 3-D model, a generative drafting document can be created wherein the projection plane becomes the plane of the screen. The system can display a visualization of the projection of the model in plane with the screen, without generating a fully computed projection. Display of the visualization can provide increased efficiency in processing time as compared to a fully computed projection. The system can also display a graphical manipulator including a circular central region with a button in the middle, wherein clicking on the button can be used as a command to the system requesting creation of the projection. The graphical manipulator software tool can also include quadrants, wherein each quadrant is associated with a direction in relation to an orthogonal axis. The four quadrants can be defined as left, right, up and down: Clicking on a quadrant can cause the projection plane to rotate by 90 degrees, or other predetermined amount, around two orthogonal axes of the model in the projec…
