Thoughts about the use of the !CMDLINE metacommand.

The !CMDLINE metacommand do have at present only one purpose: define the color that this part has under normal circumstances. Saying that all parts that have been produced only in one color should carry that metacommand. The syntax of this metacommand is simple. Example: !CMDLINE -c19 The '-c' is the parameter for colouring of the part and the number following (without whitespace) is the color number from LDConfig.ldr.

Origin on Train Track Points

Train Track Points should have its origin on the middle (each direction) of the straight track portion. By doing this it is easy to substitude one Train Track Point by another one. Also the main subparts should follow this origin.

Correction of identical vertices

Identical vertices can occur by using applications in part authoring process or by error if typing by hand. Possibilities for correction:

• Linetype 2: If vertices 1 and 2 are identical - just delete that line
• Linetype 3: If vertices 1 and 2 or 1 and 3 are identical - just delete that line
• Linetype 4: If vertices 1 and 2 identical but 3 and 4 not identical and 1 and 3 not identical - change to triangle (linetype 3). If the quad can not be transformed to a valid triangle (there are 4 possible ways!) then delete that line
• Linetype 5: If vertices 1 and 2 identical then delete that line

All other identical vertices should be inspected by human as it might be only an error in defining the vertices.
