The following only applies to FS98™ and CFS™. FS2000™
uses a new viewer that makes useless the seals and the associated JUMP PLANE/PLANE
instruction pair. When you design for FS2000™, you just need to build the sub-assies, assign them a color or a texture
and make them move
. That's it !
What is a seal...
is a chain of vertices defining a plane that is used to sort the different parts of the 3D model during the viewing
process. Parts of the 3D model can be either sub-assies, sets of sub-assies, or sets of polygons.
Let us assume a given seal interfaces the sub-assy "A" with the sub-assy "B". Depending upon the position of the virtual observer with respect to the seal, he will see "A" in front of "B", or behind it. Thus, the viewer must draw "A" after "B" or before it... The choice of appropriate seals is very important in the design of a model.
The seals are used in the Model Editor (instruction JUMP PLANE
) but they must be declared in the Graphic Editor. To do that, you just have to select an existing chain or a template and add it to the seal list which is maintained by Aircraft Designer 2000
. The plane of the seal is defined by three points of the supporting chain or template.
The seals may be displayed in the Graphic window or hidden. The show seals
option of the Utilities menu
controls the display of the seals.
