Each piece of the model should adhere to agreed upon guidelines so that they all go together. We have agreed that the origin of the model is along the edge of the floor and the front wall at the center of the screen. The Y axis points up, and the Z axis points perpendicular to the front wall out into the room. One unit is one meter. Selection of the origin is very important to enable easy positioning and rotation with subsequent tranformations.
Units are meters.
Describe logically different objects in different files, and use Inlines to combine them. DEF statements even if they are not instanced again with a USE stmt. So, please help each other as much as possible. For instance, if you find a particularly effective way to perform a modeling task, please post a message to the news group so that others can benefit from your wisdom. Likewise, if you get a digital camera to take pictures for textures, let others know so that you can both take pictures at the same time.
