reversing direction of arrow linetype

[clicker]

Hello,

I am using a custom arrow linetype, which is defined by the following code in my acad.lin support file:

 

*ARROW,Arrow1 > > > > > > >

A,.000001,-3,["\U+25BA",Standard,S=3,R=0,X=-1.35,Y=-1.35],.000001,-4

 

It works great, but I need to figure out a way to create another linetype which is similar but with the arrowheads pointing in the reverse direction. Does anyone know how to modify the code to get this result? Or is there a simpler way to reverse the orientation of the arrows?

 

I am working in acad 2008. I think there is a command in acad 2010 (RVRSLINE) which does what I want, but I don't have that version...

Please help!

much thanks,

clicker

Check this link out and the code offered by alanjt and CAB, perhaps might help.

Or perhaps you could make another linetype using "U+25C4" instead of "U+25BA"

Isn't there a lisp that will do this (reverse a linetype)?

Why don't you just rotate the line at the mid point?

OK here ya go -

 

*ARROW2,Arrow2

A,.000001,-3,["\U+25BA",Standard,S=3,R=180,X=-1.35,Y=-1.35],.000001,-4

 

notice the red stuff I changed.

 

I know this isn't a command to automatically change the direction, but at least it's another option besides rotating the line.

Another Reverse Direction lisp routine by alanjt is included in this thread:

the lisp worked great, thanks all!

Ryder- yes, I could rotate the line, but that would be more time consuming, I was looking for a quicker way...
