Topic: Ssget filter for mirrored multileader

[dexus]

Hi all,

I'm trying to select only mirrored multileaders, but I cant seem to get the ssget filter correct.

The normal of a multileader is set in the first appearance of dxf code 11 and if it is mirrored, it is set to (0.0 0.0 -1.0)

But other things like where the leaders are connected are also saved in dxf code 11.

If I try to match it directly it doesn't match anything because not all the 11's are the same:

Code - Auto/Visual Lisp: [Select]

1. (ssget '((0 . "MULTILEADER") (11 0.0 0.0 -1.0)))

If I try to find all the non default normals it matches non-mirrored multileaders as well, because it matches the second 11 as non default:

Code - Auto/Visual Lisp: [Select]

1. (ssget '((-4 . "<and") (0 . "MULTILEADER") (-4 . "!=") (11 0.0 0.0 1.0) (-4 . "and>")))

Is it possible to set an ssget filter for only the first appearance of 11?
Or is there another way to do this?

Try this :

Code - Auto/Visual Lisp: [Select]

1. (setq ss (ssget (list (cons 0 "MULTILEADER") (list 11 0.0 0.0 -1.0) (cons -4 "<or") (list 11 -1.0 0.0 0.0) (list 11 1.0 0.0 0.0) (cons -4 "or>"))))

Yes, I found it. Thank you!
I did have to add the first 11 to the <or set as well:

Code - Auto/Visual Lisp: [Select]

1. (ssget
2.   '(
3.     (0 . "MULTILEADER")
4.     (-4 . "<or")
5.       (11 -1.0  0.0  0.0)
6.       (11  0.0 -1.0  0.0)
7.       (11  0.0  0.0 -1.0)
8.     (-4 . "or>")
9.   )
10. )

10. )

I think you are making mistake with this... There should be one 11 with positive 1.0... Look careful in my example...

You were right, my previous code was incorrect.
It selected only a mleader with the arrow on a specific side.

You're code selects nothing for me.
I attached an example drawing for more testing.

[ribarm]

Try with this :

Code - Auto/Visual Lisp: [Select]

1. (setq ss (ssget (list (cons 0 "MULTILEADER") (list 11 0.0 0.0 -1.0) (cons -4 "<or") (cons -4 "<or") (list 11 -1.0 0.0 0.0) (list 11 1.0 0.0 0.0) (cons -4 "or>") (cons -4 "<or") (list 13 -1.0 0.0 0.0) (list 13 1.0 0.0 0.0) (cons -4 "or>") (cons -4 "or>"))))

Doesn't work in my version of AutoCAD, it is not able to select any mleader, does it work for you?
I'm using AuotCAD 2015.

Yes, you are right - it's not selecting in AutoCAD - I have 2022 version, but in BricsCAD it selects just what should - all of them from the right side - I have V23 where I tested, but on other PC I have V24 and I suppose it'll work and there...

This works for me on your sample drawing.

Code - Auto/Visual Lisp: [Select]

1. (sssetfirst nil (ssget "_X" '((0 . "MULTILEADER") (13 -1.0 0.0 0.0))))

[ribarm]

Correct...
It selects in AutoCAD 2022 on my Laptop...

1. (sssetfirst nil (ssget "_X" '((0 . "MULTILEADER") (13 -1.0 0.0 0.0))))

Thanks ronjonp! This does work on my version of AutoCAD.
So switching to 13 instead of 11 does the trick, I guess since there is only one occurrence of this number it doesn't have any problems.

And ribarm, thanks for your input as well

It should be noted that Mleaders which use a block instead of Mtext do not have the DXF 13 code.
