I was working on creating a few new linetypes for work when I came across this problem:  The linetypes I make work fine for the session of ACAD, but when I come in the next day and try to show them to my boss, they just stop working.  I've gone over the code with a fine-toothed comb, and nothing is different; they just only work for one day.  The linetype I created uses a .shx file that I created using the MKSHAPE command, but the ones that have shapes I wrote myself don't work either.  Please give me a reference or something so my hours of work can seem justified!

ok, new question:  I have a linetype that is made for ditches.  it looks like a dash with an arrow on the end, followed by 3 dots, and it repeats.  It works great except for one thing.  When I draw arcs one way, the arrow keeps on pointing with the line, but when I draw arcs the other way, the arrow flips around and points backwards.  I have read comments about how text orientates itself towards the center of the arc, but I am hoping to make the arrow keep pointing with the line without using the absolute rotation because it looks like crap with the arrows.  Any suggestions?
