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!

Never mind, I figured it out... In case anyone else has this issue, the file name for the .shx file that you use in the code of the linetype works as just "shape name.shx" for the one session, but when you reload, it no longer knows where the file is located by only that name.  If you change the file name to be the total text string ie. x:/standards/linetypes/shape name.shx, the linetype works fine!

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?
Thanks everyone...
