Basic BinEdit (The Model Menu) Click the menu bar to goto a page about each section.
Rotate X - Rotate Y - Rotate Z - | This is not the same as the Play feature. This has to do with the model's orientation in the game, not just the view in BinEdit. Use these options if you want to change the direction a truck body faces, for example, or if you want to stand something upside down. You will be prompted to enter the number of degrees for the rotation. Often helpful when converting from wavefront format.
Center X - Center Y - Center Z - Center All - | This will center the model along the axis you choose, or all of them at the same time. Centering a model usually means it will be easier to place in your track. The Y axis is especially important if you want the model to sit properly on the ground. Note, however, that centering is not always wanted. For example, truck bodies don't need to be centered on the Y axis.
Resize - Use this to make your model larger or smaller. You may keep the width, length and height proportionate or not. Translate - Move the model or move selected verticies. Normalize texture - Map all faces with a single texture. You select the texture. Write textures to textfile - This will create a text file list of all the textures used by the model. It can be helpful for creating a lst file for a truck. Make sure you type .txt when prompted for a file name. BinEdit does not create a file extension by default.
