CHANGE PROJECTION

Purpose:

This function is used to change the projection of a user-indicated model view.

Instructions:

1. In the Tools menu, click Model View, then Change Projection.

2. Indicate model view to be changed. The next possibilities for defining the projection are shown in the window Choose option:

   • Same As View
     Indicate an existing view in the drawing, and the projection will be the same as in the indicated view.

   • Point Vector
     Indicate a point in the projection plane, and a vector defining the normal to that plane.

   • Three Points
     Indicate a point in the projection plane, and two vectors defining the U-axis and the V-axis of the projection plane.

   • Two Cursor Positions
     Two cursor indications in an existing view define the U-axis of the new projection; the V-vector is the same as the normal to the projection indicated. A third cursor indication defines the normal, and thereby the observer side, of the new projection plane.

   • 3D Rotate

   • Starting from an existing view, the user defines the new projection by rotating around the co-ordinate axes. This can be done either in predefined steps, or in arbitrary steps via keyboard input. The resulting projection is shown with a small coordinate system and can be applied to the view by Operation complete.

   • Predefined Projection
     There is a possibility to define 5 standard projections in the default handling, and each of these is displayed and is accessible as a direct choice.

3. Select either one of the ways to define projection or predefined projection.

4. If the drawing is an Assembly ADP drawing (a drawing generated by the Assembly ADP utility) the system will ask you if you want to re-run tasks. This will regenerate the labels and the bounding box that was created by the Assembly ADP.

   Please note that these tasks are a part of the Assembly ADP application and they will only work if you are in Marine Drafting. It will not work in Hull Design.

Options:

None.

Result:

The selected view changes its projection as per User’s choice.
