AutoTURN Pro generates parametric plan views for custom vehicles based on the part configuration and vehicle dimensions. However, since a generic plan view may not provide an accurate enough representation of the vehicle it is recommended that users create their own drawings for custom vehicles.

General Guidelines

• Orient drawings so that the vehicle points to the right and the front center of the vehicle part is at exactly coordinate 0,0.
• Do not draw wheels - they are drawn automatically by AutoTURN Pro.
• Any amount of detail can be included to represent the vehicle's plan view as long as the vehicle's outline is continuous and goes on its own layer and a wheelbase line is drawn the same length as the wheelbase value of the custom vehicle. The drawing must be drawn full scale.
• Each part of a multi-part custom vehicle must be drawn individually. The first drawing's name is the same as the Name field of the custom vehicle (e.g. the name of the first drawing of a two part vehicle would be: Semi Trailer.dwg). Each subsequent drawing must be named the same as the first drawing with the suffix @ followed by the trailer number (e.g. the second drawing of the two part vehicle would be: Semi Trailer@1.dwg).

Drawing Layers/Levels

Drawings should be created with the following layer/level setup:

Layer/Level	Description
TSOUTLINE	All lines pertaining to the extents of the vehicle
TSDETAILS	All detail lines inside the vehicle (windows, doors, contours, etc.)
TSWHEELBASE	This single line must exactly match the length of the custom vehicle's wheelbase. This line is used to scale the drawing when it is used by AutoTURN Pro.

Creating the Drawing - AutoCAD/BricsCAD/ZWCAD

1. Start a new drawing.
2. Create a new layer named "TSOUTLINE" and draw the extents of the vehicle on this layer.
3. Create a layer named "TSDETAILS". Draw all the details inside the basic outline of the vehicle on this layer. This will improve display performance by allowing AutoTURN Pro to separate the drawing elements and only display the vehicle outline while dragging and running animations.
4. Create a layer named "TSWHEELBASE". Draw a line that exactly matches the wheelbase value of the custom vehicle on this layer. It can be located anywhere in the drawing and will not display in the vehicle preview dialog boxes.
5. Create a folder in the Vehicles User folder to save the drawing to (for information on the location of the user data, see General Installation Notes: Default User Data Location). The folder name must be the same as the Library field of the custom vehicle.
6. Save the drawing to the folder created in step 5.

Creating the Drawing - MicroStation

Note: AutoTURN Pro can use AutoCAD version 2007 (and older) DWG format drawing files in MicroStation V8i. AutoTURN Pro will use cell files if MicroStation users prefer to create them as outlined below.

1. Start a new design file.
2. Create a new level named "TSOUTLINE" and draw the extents of the vehicle on this level.
3. Create a new level named "TSDETAILS". Draw all the details inside the basic outline of the vehicle on this level. This will improve performance by allowing AutoTURN Pro to separate the drawing elements and only display the vehicle outline while dragging and running animations.
4. Create a level named "TSWHEELBASE". Draw a line that exactly matches the wheelbase value of the custom vehicle on this level. It can be located anywhere in the drawing and will not display in the vehicle preview dialog boxes.
5. Create a new cell library named the same as the Name field of the custom vehicle.
6. Create a cell and add it to the new library. The cell can be given any name. There must be only the one cell in this library.
7. Create a folder in the Vehicles User folder to save the drawing to (for information on the location of the user data, see General Installation Notes: Default User Data Location). The folder name must be the same as the Library field of the custom vehicle.
8. Save the cell library to the folder created in step 7.
