To solve this issue I normally do the following:
- calculate the model (all lines)
- annotate the model
- create new directory "Drawing models"
- copy the calculated model and rename it to show line ID
- do the copying as many times as I have lines (Do not use Save As from CAESAR II)
- Open each model and using list delete all elements not belonging to the line
- Iso the lines. Because the model name is line name it is good description for the drawing. I also include the model revision number into the name.
