Selects everything that touches pre-selected objects

June 15

Hello friends,

I have such a lisp, it works even if the selected objects is few,

but when the selected objects are to much it wastes a lot of time and sometimes gives an error.

How can we make this better?

Not sure what your exactly after, is it getting intersection points of objects touching the red pline ? If so use a ssget "F" to get objects. Note it also selects the pline object.

(defun c:test ( / plent co-ord ss ss1 ss2 x y)
(prompt "Select plines")
(setq ss (ssget '((0 . "LWPOLYLINE")(8 . "WALL"))))
(setq ss2 (ssadd))
(repeat (setq x (sslength ss))
  (setq plent (ssname ss (setq x (1- x))))
  (if plent (setq co-ord (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget plent)))))
  (setq co-ord (cons (last co-ord) co-ord))
  (setq ss1 (ssget "F" co-ord (list (cons 0 "LINE,LWPOLYLINE,ARC,CIRCLE,POINT,TEXT,MTEXT,insert"))))
  (repeat (setq Y (sslength ss1))
   (setq ss2 (ssadd (ssname ss1 (setq y (1- y))) ss2))
  )
)
(princ (sslength ss2))
(princ)
)

Good day Mr. Bigal,

Please see attached foto and video

1.Select object or objects
2.Command test
3. Touched objects are automatically selected

When the selected object(Red Pline) is few(1 or 2 pcs.), it works normally,

but when the selected objects (Red Pline) are too much(100pcs.),

Process takes too much time or error.

I updated code above and got 1189 objects. Instantly.

OK the dumb question why do it ? What is end goal.

Hi BIGAL,

its possible select the text layer(it contains multiple mtext) first, select the overlapping polylines and move them to different?

June 17

just add this line

(sssetfirst nil ss2)

below of this line

(princ (sslength ss2))

you will get this

and then

you want to select multileader too,

edit this line

(setq ss1 (ssget "F" co-ord (list (cons 0 "LINE,LWPOLYLINE,ARC,CIRCLE,POINT,TEXT,MTEXT,insert"))))

(setq ss1 (ssget "F" co-ord (list (cons 0 "LINE,LWPOLYLINE,ARC,CIRCLE,POINT,TEXT,MTEXT,INSERT,MULTILEADER"))))

Mr. Exceed Good day,

The first selected objects are: "not only LWPOLYLINE, need (ALL objects) Is it possible this?
(setq ss (ssget '((0 . "*****here ALL objects****"))))
(setq ss1 (ssget "F" co-ord (list (cons 0 "*****here ALL objects****"))))

Also is it possible no need the layer? without layer. (8 . "WALL"))))

June 18

if you need all object

you cad do it with just delete '((0 . ~~~))

(setq ss (ssget '((0 . "LWPOLYLINE")(8 . "WALL"))))

(setq ss (ssget '((8 . "WALL"))))

or you want all of layer

(setq ss (ssget))

and also ss1

(setq ss1 (ssget "F" co-ord (list (cons 0 "LINE,LWPOLYLINE,ARC,CIRCLE,POINT,TEXT,MTEXT,insert"))))

(setq ss1 (ssget "F" co-ord))

If you want to exclude wall layer from the selected objects

(setq ss1 (ssget "F" co-ord '((-4 . "<NOT") (8 . "WALL") (-4 . "NOT>"))))

June 18

Mr. Exceed Good day,

for all of layer and all of objects

I tried but didn't happen.

Cloud you please check?

I have attached the dwg file.

(defun c:test2 ( / plent co-ord ss ss1 ss2 x y)
(prompt "Select plines")
(setq ss (ssget))
(setq ss2 (ssadd))
(repeat (setq x (sslength ss))
  (setq plent (ssname ss (setq x (1- x))))
  (if plent (setq co-ord (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget plent)))))
  (setq co-ord (cons (last co-ord) co-ord))
  (setq ss1 (ssget "F" co-ord))
  (repeat (setq Y (sslength ss1))
   (setq ss2 (ssadd (ssname ss1 (setq y (1- y))) ss2))
  )
)
(princ (sslength ss2))
(sssetfirst nil ss2)
(princ)
)

Tried removing '((0.~~~~)).

But not working.

Could you please update the code

June 19

because, all objects were selected in ssget by deleting that

but in later process (collecting dxf 10) is only works for polylines.

The process of obtaining borders for all objects is not as easy as you might think.

Depending on your purpose, if you only want the accuracy of the rectangle containing the shape,

using vla-getboundingbox to get the lowest and lowest points,

change the last ssget to "c" and use it.

If you need exactly the border,

you can use Lee Mac's Outline Object https://www.lee-mac.com/outlineobjects.html

to obtain the border polyline and then use that polyline.

In this process, you must also consider how to handle inside closed lines, like donuts inside the block

and how to handle cases such as lines and arcs that do not create an area.

I don't know what the purpose of this is,

but if there are a lot of target objects and the type of border cannot even be specified,

It is better to separate the layers. Or, it is more appropriate to select using QSELECT.

i have small polylines and DW text on it. so i want select those polylines and change those pl into another layer.

all polylines are in same layer so, i have this text to select the overlapping objects.

June 19

@srikanth_0126 Mr, if you need a different lisp, please open a new topic.

My topic is to select other objects that touch the selected objects.

June 19

Hi @macros55,

its a same thing but, i select text objects to select touching polylines.

June 19

@Exceed Mr, I need to select other objects that touch the selected objects. But not only selected Pline, sometimes " 3dpolyline, line, block, circle text, mtext, etc."

Mr Tsuky, Good day, It's good to see you again. how are you?

I tried some object (circle, line, arc)working ,but other (pline, block, point, text,revcloud, etc.) not working.

I need for all of objects

Please see attached test ss3.dwg file.

test ss3.dwg

June 21

I fixed my code, please reload it from my previous post.
This works for any curvilinear entity.
It can also work for a block if it is made up of nested curvilinear objects.

On the other hand, for other objects such as texts, it is much more complicated because it would be necessary to take into account the justification of the text, its rotation, possibly the UCS used, or that the text is contained in a block (with again : an insertion point, a rotation, an insertion, a scale) to obtain a selection path (_FENCE) from the function (textbox). So really a headache for transforming coordinates...

June 21

Mr. Tsuky, I tried the code , I think it can make selections one by one.

Is it possible to select more than one object at the same time? for example, I need to select all object(not only pline) which are touching my all objects(not only pline) in one time

Edited June 21 by macros55

June 21

It's doable, but in this case I can no longer use the blocks as a source.
You can use _QSELECT (or SELECTSIMILAR) or nothing at all for manual selection before using the code.
