I have this leader lisp I would like to modify but not sure how to make it work. The code below, asks the user to select the text they want to add a leader to. I then asks for the location where the user want the arrowhead then the location for the endpoint of the tail. The code sets the other end of the tail at the specified distance provided in the code.

 

What I would like it to do is once the arrowhead location has been established, the code will set the remaining two points based on the following criteria:

  1. The first end of the tail is .04 from the insertion point of the text (Currently the code is set to 0.00)
  2. The second point is 0.06 from the last point or 0.10 from the insertion point of the selected text.

Here is the entire code so you can see how thins works...

Never said I wrote the code, I just want to customize it a bit to meet our needs. I found the routine this morning and thought it was great. It is an excellent routine by the way. Just need help in tweaking it a bit

 

Have any suggestions?

I'd suggest that you read and add the following to the code

 

That is added. I just didn't post all of the code and since Timothy posted his original code there really isn't a need. Just trying to save some space is all.

 

NOTICE TO ALL

 

The code I posted was wrtten by:

 

Timothy G. Spangler

Copyright © August, 2007

 

if you want a copy then see his post above.

 

Satisfied? gezz lighten up.

 

Now can we actually get back to the original idea here. Can that code be tweaked to allow for the criteria set in my first post? I will give BILLBOARD CREDIT for the fix cuz I really don't care about that. Just would like a routine that can do this.

Zen,

 

I am just trying to maintain the integrity of the code that's all. If you leave the header in tact it will make it that much easier to find the original owner when you need it modified.....If you downloaded the code without a header let me know where you got it from. Please.

 

 

As for modifying the code...I am at home know but when i get to work tomorrow i'll give it a look and post back.

 

P.S. If you get use out of it, great, let me know so i know that my efforts are wasted on myself alone.

I am sure I will get use out of it because I was having trouble with my users making leaders of all size tails; small, long, none at all, it was very frustrating. I even made a block of the leaders to comy and just copy, move rotate then just move the arrowhead to the entity they were noting. They still did their own thing. Your code will ensure that all they have to do is select the text and point to the item they are noting. Done deal.

 

I look forward to seeing your code. I am going to be a AU all next week but once I am back in the office I will let you know how the users like it.

Nice.

It's been here since 18th Sep 2006, at the start of the forum thread list.

A sticky even.

Sounds like it is something important to me.

I can't believe he's even changed the syntax to make it look different... poor Tim - all that work, and no credit when credit's due.
