I think something might be wrong with your file.
In this file I cannot get it to work.
But if I extract this Marker object from the Embedded Library into a folder in the hard drive, then:
1. Do a New & Reset (CTRL+ALT+N).
2. Load the Marker object into the Embedded Library.
3. Set it for the Section Marker and place the Section Line.
then it works perfectly.
There must be something between the file and the MUL2 command in the object. If I comment the MUL2 line in the 2D Script then it works fine. But in that case it will not be resizable. (In that case you can resize it in the 2D Symbol to be the size you need.)
